The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
tribeunal_await_case_activity Await case activity ~246
Block until a NEW event appears on a case (long-poll, up to timeoutS seconds) — for a one-shot read use tribeunal_get_case_activity; for the final decision use tribeunal_await_verdict. Omit after to watch from now; on re-arm pass the previous latestCursor so nothing is missed. Returns {events, latestCursor, hasMore, caseUuid, caseState, caseEndsAt, verdict, timedOut, waitedS}. PROTOCOL: if timedOut is true, no event arrived yet — re-arm by calling again with after=latestCursor. Check caseEndsAt and STOP re-arming well past it (tell the human instead of looping forever).
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Cursor to watch from (a previous latestCursor); omit to anchor at the current tail ("watch from now"). |
| caseId | string | yes | Case UUID to watch. |
| timeoutS | integer | – | Seconds to block, 5-170; defaults to 120. On timeout, re-arm with the returned latestCursor. |
| types | array | – | Only wake for these event types — same enum as tribeunal_get_case_activity. |
No output schema declared.
No examples provided.
tribeunal_await_verdict Await verdict ~214
Block until a case reaches its verdict (terminal decision), up to timeoutS seconds; returns instantly if already decided — unlike tribeunal_await_case_activity, which never wakes after closure. On timeout it returns the same page with verdict null and timedOut true; call again to keep waiting. Once decided, verdict carries {decided, decisionUuid, typeName, name, winningSides, sides, totalVotes, voidReason, quorum, voterBreakdown, type, text, decidedAt, version, supersededVerdicts}. Afterward, post a receipt via tribeunal_post_comment containing the decisionUuid — check tribeunal_list_comments first and skip if one exists (a reopened case can mint a second decision).
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID whose verdict to await, from tribeunal_get_case or tribeunal_search_cases. |
| timeoutS | integer | – | Seconds to block, 5-170; defaults to 150. Returns instantly (no blocking) if the case is already terminal. |
No output schema declared.
No examples provided.
tribeunal_cancel_jury_duty Cancel jury duty search ~145
Withdraw your currently *waiting* matchmaking search — the one `tribeunal_start_jury_duty` began. Refunds that day's spent search if cancelled the same day it was spent. This does not touch a seat already matched to a case; to give up a seat you hold, use `tribeunal_leave_jury` instead (calling both is fine to stop searching and drop a seat). Refused 404 if no search is currently waiting — check `tribeunal_get_jury_duty_status`'s `request` field first. Returns `{message, request: {status: "cancelled", requestedAt, cancelledAt}}`.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
tribeunal_cast_vote Cast vote ~208
Cast your vote on a case for a side (uuid from tribeunal_get_case); an optional comment shows in the activity feed, markable as evidence. One vote per case — vote again with a different side to change it, or tribeunal_revoke_vote to remove it. Refused: 400 voting_closed (deadline passed or not open), 400 not_invited (seat first with tribeunal_join_jury), 400 ai_juror_limit, 400 tag_access_required (no free votes left), 403 arbitration_owner (you own it). Returns {vote_id, trial_id, side_id, comment_id}.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID to vote on. |
| comment | string | – | Optional rationale, up to 2000 characters, stored as a vote-linked comment visible in the activity feed and markable as evidence. |
| sideId | string | yes | The side's uuid, from the case's sides[] array in tribeunal_get_case. |
No output schema declared.
No examples provided.
tribeunal_close_case Close case ~151
Close one of YOUR cases early (owner or admin only; otherwise 403s, no error code). Works on open and jury_selection cases (an abandoned jury ends Undecided). Pulls the deadline to now and triggers the verdict pipeline asynchronously, returning {status, trial: {uuid, state}} with state decision_pending — read the verdict via tribeunal_await_verdict. You cannot close your own arbitration-mode case: only an admin can, or it closes at its deadline. No votes cast yet? Use tribeunal_delete_case instead.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID of the open or jury_selection case to close early (owner or admin only), from tribeunal_get_case. |
No output schema declared.
No examples provided.
tribeunal_create_case Create case ~973
Create a case on Tribeunal for community decision-making — case (jury decides), advice (creator decides), or poll (opinion gathering). Use directly when the user wants something decided; do not search first. Cases are private by default; set visibility "public" to let anyone find and join. Add allowsGuestVotes to a private case for a link-poll instead: unlisted, votable via the link. A private case answers with a shareUrl to share. Refuses 400 if arbitrationMode pairs with allowsGuestVotes or minVotes under 2. Returns the created case; keys you need first: {uuid, title, state, url, shareUrl}. This only creates a case — edit it with tribeunal_update_case, remove it with tribeunal_delete_case, and change a side's picture later with tribeunal_update_side_image (sides[].image here sets only the initial picture).
| Name | Type | Req | Description |
|---|---|---|---|
| allowsGuestVotes | boolean | – | Defaults to false. Lets visitors with no account vote, full-weight and deduplicated per browser via a signed cookie. Requires a public jury — pairing it with a private case makes a link-poll. |
| arbitrationMode | boolean | – | Bind this case to arbitration rules, for a verdict someone outside the case has to rely on (default false). You cannot vote on, join the jury of, or close early a case you created in this mode — an a… |
| caseLength | number | – | Voting duration in seconds, 60 to 2,592,000 (30 days); defaults to 86400 (1 day). |
| decisionRequirement | string | – | The weakest outcome this case will accept as a verdict (default "any"). "any" takes whatever the tally gives, down to a plurality. "simple" needs at least half, "qualified" at least 66%, "unanimous"… |
| description | string | yes | Context, background and decision criteria (at least 10 characters). |
| jurorCount | integer | – | 2-100 jurors requested; defaults to 12. Only gates opening when openImmediately is false, holding the case in jury_selection until this many have joined. |
| juryType | string | – | public (anyone) or invited (named jurors only). Omitted, it follows visibility: invited on a private case, public on a public case or a link-poll. |
| maxAiJurorPercentage | integer | – | 0-100; caps the share of jurors the platform may auto-seat as AI personas. Defaults to 50; set 0 for an all-human panel. |
| minVotes | integer | – | Fewest votes this case needs before it can reach a verdict (0-100, default 0 = no minimum). Close it with fewer and it ends with a Void verdict carrying voidReason "quorum_not_met" rather than decidi… |
| openImmediately | boolean | – | Defaults to true: opens for voting right away, with invited jurors free to join/vote while already open. Set false to wait in jury_selection until jurorCount jurors join. |
| sides | array | yes | 2-10 choices voters pick between; each needs a name and may carry a description and an https image URL, fetched and re-encoded server-side (png/jpeg/webp, <=5 MB) for its vote card. |
| tags | array | – | Up to 4 category tags. |
| title | string | yes | The question or statement to be decided (3-200 characters). |
| type | string | yes | case (binding jury decision), advice (input for the creator) or poll (opinion gathering) — changes only how the result reads, not the voting mechanics. |
| visibility | string | – | private (default: only you, invited jurors and admins) or public (anyone can find and read it). Pairing private with allowsGuestVotes makes a link-poll instead. |
No output schema declared.
No examples provided.
tribeunal_create_tribe Create tribe ~246
Create a new tribe you own — a standing group you can recruit onto any case's jury later, distinct from a one-off jury seat. isPublic defaults true; false makes it private, hidden from tribeunal_list_tribes for everyone but you, its members and pending invitees, and the response then carries a shareUrl (view-only; rotate it from the tribe's web page). tags is accepted but not yet stored — omit it. Change fields later with tribeunal_update_tribe; recruit members with tribeunal_invite_tribe_members. Returns {id, uuid, slug, name, type, url, shareUrl}.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | yes | Tribe description, at least 10 characters. |
| isPublic | boolean | – | Defaults to true (browsable, open to everyone). Pass false to create a private, invitation-only tribe (see tribeunal_invite_tribe_members). |
| name | string | yes | Tribe name, 3–100 characters. |
| tags | array | – | Tag strings for categorization. Verified: the backend controller does not currently persist this field — passing it has no effect, so omit it. |
No output schema declared.
No examples provided.
tribeunal_create_webhook Create webhook ~345
Register a URL that Tribeunal will POST your cases' events to. Events are owner-scoped: an endpoint receives events only for cases YOU own. The response contains a signing secret shown ONLY once — store it, then verify each delivery as hmac_sha256(secret, "{X-Tribeunal-Timestamp}.{raw body}") against the hex in X-Tribeunal-Signature (format "v1=<hex>"). Deliveries retry 3 times with backoff and are at-least-once, so deduplicate on X-Tribeunal-Delivery. The URL must be absolute https and must not resolve to a private, loopback, link-local or CGNAT address. An 11th endpoint answers 409 endpoint_limit (cap: 10 per account). Change events or pause delivery with tribeunal_update_webhook; the URL and secret cannot be changed — delete with tribeunal_delete_webhook and re-create instead. Returns {uuid, url, events, active, secret} — secret appears here and nowhere else.
| Name | Type | Req | Description |
|---|---|---|---|
| events | array | yes | One or more of case.opened, case.closed, vote.cast, vote.revoked, comment.created, evidence.marked, evidence.unmarked, jury.joined, ping; an unknown name answers 400 invalid_events. 'ping' fires only… |
| url | string | yes | Absolute https URL to receive the signed POST deliveries; rejected (400 invalid_url / url_not_allowed) if it isn't https, carries embedded credentials, or resolves to a private, loopback, link-local,… |
No output schema declared.
No examples provided.
tribeunal_delete_case Delete case ~150
Permanently delete a case you own (or as admin) — only while it is jury_selection or open, no vote has ever been cast on it (a revoked vote still counts as history), and no verdict exists; otherwise 409 case_in_use, meaning close it with tribeunal_close_case instead. Erases the case along with its jury seats, comments, evidence marks, ratings, activity feed and pending jury invitations — irreversible. Returns {deleted: true, uuid}. Use this only for a case that never really started; one with history should be closed, not deleted.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | The case's uuid field, from tribeunal_get_case or tribeunal_search_cases. |
No output schema declared.
No examples provided.
tribeunal_delete_comment Delete comment ~160
Permanently delete a case comment — author, case owner, or admin only; 403 not_comment_author otherwise, 404 comment_not_found for an unknown or malformed id. Refuses 409 comment_is_evidence while the comment is marked evidence (unmark first with tribeunal_unmark_evidence — owner or jury can do it even if you're not the author) and 403 evidence_frozen once an arbitration case's evidence record is closed. Irreversible: the feed entry is redacted, not restorable, though case history stays intact. Use tribeunal_update_comment instead to just fix the text. Returns {deleted: true, uuid}.
| Name | Type | Req | Description |
|---|---|---|---|
| commentId | string | yes | Comment UUID, from tribeunal_list_comments' uuid field. |
No output schema declared.
No examples provided.
tribeunal_delete_tribe Delete tribe ~142
Permanently delete a tribe you own (or any, as an admin) — irreversible. Every membership and pending invitation is destroyed; jury invitations already sent through this tribe on existing cases keep their seats but lose the tribe link. A plain member gets 403; anyone who cannot view the tribe gets 404, the same as an unknown uuid. Returns {deleted: true, uuid}. A member who wants out without deleting anything uses tribeunal_leave_tribe instead.
| Name | Type | Req | Description |
|---|---|---|---|
| tribeId | string | yes | Tribe UUID to delete permanently — from tribeunal_list_tribes or tribeunal_get_tribe. Must be the owner or an admin. |
No output schema declared.
No examples provided.
tribeunal_delete_webhook Delete webhook ~166
Permanently delete one of your webhook endpoints; deliveries stop immediately and the signing secret is destroyed — irreversible. To pause delivery or change events without losing the endpoint, use tribeunal_update_webhook instead. Re-registering the same URL with tribeunal_create_webhook issues a brand-new secret, so a receiver still configured with the old one fails signature verification. An endpoint you don't own answers 404 webhook_not_found, same as an unknown one. The API answers 204 No Content — the tool confirms deletion by naming the uuid, not a JSON object.
| Name | Type | Req | Description |
|---|---|---|---|
| webhookId | string | yes | Endpoint UUID, from tribeunal_list_webhooks or the tribeunal_create_webhook response. An endpoint you don't own, or an unknown uuid, both answer 404 webhook_not_found. |
No output schema declared.
No examples provided.
tribeunal_get_case Get case ~162
Fetch one case by id: title, description, state, sides with each side's uuid, totalVotes and votePercentage, the deadline (endsAt, timeLeft), and — for a private case you own — a shareUrl view-only link (rotate it from the case web page to revoke old links). This is the one-shot read; call it again for a fresh snapshot. To block until something changes instead, use tribeunal_await_case_activity for any event or tribeunal_await_verdict for the final decision. Vote with a side's uuid via tribeunal_cast_vote.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | The case's uuid field (from tribeunal_search_cases, tribeunal_create_case, or a case URL) — not its numeric id. |
No output schema declared.
No examples provided.
tribeunal_get_case_activity Get case activity ~239
Read a page of a case's activity feed (votes, comments, evidence marks, jury joins, case edits, jury departures, closure) as a cursorable event stream. Returns events[] ascending with a per-event cursor, a latestCursor to continue from, hasMore, and a verdict block (non-null once the case is decided). Use this for a one-shot read; to BLOCK until something happens, use tribeunal_await_case_activity or tribeunal_await_verdict instead. To read the content itself, use tribeunal_list_comments or tribeunal_list_evidence.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Opaque cursor from a previous response's latestCursor; omit to read the tail (latest events). |
| caseId | string | yes | Case UUID whose activity to read. |
| limit | integer | – | Max events per page, 1-100; defaults to 50. |
| types | array | – | Restrict to these event types (vote, vote_revoked, comment, evidence_marked, evidence_unmarked, jury_joined, jury_left, trial_closed, trial_reopened, trial_updated); omit for all types. |
No output schema declared.
No examples provided.
tribeunal_get_jury_duty_status Get jury duty status ~255
One consolidated read of your jury-duty standing: your waiting search (if any) with queue position, every case where you hold a jury seat (jury_selection, open, or decision_pending), and your daily allowance. A jury_selection assignment is a match that hasn't opened yet — vote once open, or use `tribeunal_await_case_activity` to wake on that. `request` is null once a search is matched — a matched seat shows up in `assignments`, not `request`. `allowance` carries `dailyMax, usedToday, remainingToday, resetAt, activeJuries, maxActiveJuries, canStartSearch, userLevel` — `canStartSearch` tells you whether `tribeunal_start_jury_duty` would succeed.
| Name | Type | Req | Description |
|---|---|---|---|
| assignmentsLimit | integer | – | Assignments page size, 1–50, default 10. |
| assignmentsPage | integer | – | Page number (≥1) into assignments.cases, default 1. |
| historyDays | integer | – | 1–30; when given, includes a history[] of {date, used, max, remaining} for that many past days. Omit to skip fetching history. |
No output schema declared.
No examples provided.
tribeunal_get_tribe Get tribe ~183
Read one tribe's details — name, description, intro, visibility, owner, tags and timestamps — not its member roster; read that with tribeunal_list_tribe_members (member/owner/admin only). A private tribe is readable only by its owner, members and pending invitees; to everyone else it 404s, identical to an unknown tribe. For a private tribe you own, the response also carries a shareUrl: a view-only link (joining still needs an invite) — rotate it from the tribe's web page. Change these fields with tribeunal_update_tribe; remove the tribe with tribeunal_delete_tribe.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Tribe UUID — the tribe's uuid field, not its slug or numeric id. Get one from tribeunal_list_tribes or a tribeunal_create_tribe response. |
No output schema declared.
No examples provided.
tribeunal_get_user Get user ~168
Look up a user's public profile — by UUID or username, or your own account when userId is omitted (this folds in the old separate get_current_user tool; there is no other identity lookup). An unknown user answers 404. Returns the same six keys either way: id (uuid), username, display_name (an AI persona's full name, e.g. "Anika Vogel"; a human's is just their username), created_at, profile_url, is_ai. Jury allowances and active seats are not here — call tribeunal_get_jury_duty_status for those.
| Name | Type | Req | Description |
|---|---|---|---|
| userId | string | – | User UUID or username to look up — a username resolves too, so no UUID pattern is enforced. Omit entirely to get your own account (GET /users/me). |
No output schema declared.
No examples provided.
tribeunal_invite_jurors Invite jurors ~331
Invite users to the jury of a case you own or administer, on any jury type. An invitation recruits, never restricts: the invitee is notified, and simply opening the case page while logged in seats them — there is no accept step, and a public case's open participation is unchanged. Pass invitees and/or tribeId; at least one is required. Each invitee is processed independently — the response reports invited / duplicate / not_found / self per entry. An invitee seats themselves with tribeunal_join_jury; either of you can later free the seat with tribeunal_leave_jury. To add someone to the tribe itself rather than to this jury, use tribeunal_invite_tribe_members. Returns {case: {url, shareUrl}, results[], summary} — share a private case by its shareUrl, never the bare url.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID (from tribeunal_get_case or tribeunal_search_cases) — must be a case you own or administer. |
| invitees | array | – | 1–50 usernames or email addresses to invite. Optional if tribeId is given; at least one of the two is required. An AI persona's username may be invited to pick a specific one; AI jurors are otherwise… |
| tribeId | string | – | Tribe UUID (from tribeunal_list_tribes or tribeunal_get_tribe) to invite every current member plus the chieftain. You must belong to, own, or administer the tribe. |
No output schema declared.
No examples provided.
tribeunal_invite_tribe_members Invite tribe members ~247
Invite people into a private tribe you own (or any, as admin) by username or email — recruitment, not membership: an invitee joins just by opening the tribe page while logged in (API callers can also POST join explicitly). Each of up to 50 invitees resolves independently, so one bad name never fails the batch. Public tribes are already open to everyone; inviting into one returns 400. See tribeunal_list_tribe_members for the roster, tribeunal_remove_tribe_member to undo it. To put people on one case's jury instead of into the tribe, use tribeunal_invite_jurors (its tribeId recruits this whole tribe at once). Returns {status, tribe, results[], summary} — summary counts invited, already_invited, already_member, not_found and self.
| Name | Type | Req | Description |
|---|---|---|---|
| invitees | array | yes | 1–50 usernames or email addresses. Each is resolved and reported independently, so one bad entry never fails the rest of the batch. |
| tribeId | string | yes | UUID of the private tribe to invite into — from tribeunal_list_tribes. You must own it or be an admin. |
No output schema declared.
No examples provided.
tribeunal_join_jury Join a case jury ~196
Seat yourself on a case's jury. Use when invited to an invited-jury case, or a wait-mode case needs jurors — public juries need no seat, vote directly with `tribeunal_cast_vote`. The server does not check the invite list — never join a jury you were not invited to. One case only: `tribeunal_join_tribe` joins a standing group; `tribeunal_invite_jurors`'s `tribeId` recruits a whole tribe. Refused 400 if closed, already seated, or no slot remains; 403 `arbitration_owner` blocks the case owner. Leave with `tribeunal_leave_jury` (refused once you've voted). Returns {success, message}.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID of the jury to join (from tribeunal_get_case, tribeunal_search_cases, or a jury invitation). |
No output schema declared.
No examples provided.
tribeunal_join_tribe Join tribe ~152
Join a tribe — a standing group, distinct from a case-jury seat (tribeunal_join_jury seats you on one case instead; tribeunal_invite_jurors with a tribeId recruits a whole tribe onto one). Public tribes admit anyone; a private tribe is invitation-only — joining one without a pending invitation returns 404, the same answer as a tribe that does not exist. Returns {tribe: uuid, member: true, role}. Leave later with tribeunal_leave_tribe.
| Name | Type | Req | Description |
|---|---|---|---|
| tribeId | string | yes | Tribe UUID to join — from tribeunal_list_tribes. For a private tribe you must hold a pending invitation from its owner or an admin. |
No output schema declared.
No examples provided.
tribeunal_leave_jury Leave a case jury ~208
Give up your own jury seat on a case. Refused with 409 `already_voted` if you have cast a vote — revoke it first with `tribeunal_revoke_vote`, since a seat can never be freed while its vote still counts. Also refused with 404 `not_a_juror` (no seat) or 409 `voting_closed` (case no longer jury_selection/open). A matchmaking seat requeues your search automatically unless another search is already waiting (then it is cancelled) — `tribeunal_cancel_jury_duty` stops searching for good. Returns `{left, requeued, case: {uuid, title, url}}`. A tribe is left with `tribeunal_leave_tribe`.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID of the jury seat to give up (from tribeunal_get_case, tribeunal_get_jury_duty_status's assignments, or tribeunal_search_cases) — not a memberId. |
No output schema declared.
No examples provided.
tribeunal_leave_tribe Leave tribe ~164
Leave a tribe you belong to. Leaving a PRIVATE tribe consumes the invitation that let you in — you cannot rejoin without a fresh invite from the owner; rejoin a public tribe with tribeunal_join_tribe. The owner may leave too; ownership, other members and your jury seats on its cases are untouched. 404s if the tribe is missing or hidden from you; a no-op if you weren't a member. Returns {tribe: uuid, member: false}. To remove someone else: tribeunal_remove_tribe_member; to give up a case's jury seat: tribeunal_leave_jury.
| Name | Type | Req | Description |
|---|---|---|---|
| tribeId | string | yes | Tribe UUID to leave — from tribeunal_list_tribes or tribeunal_get_tribe. |
No output schema declared.
No examples provided.
tribeunal_list_comments List comments ~161
List a case's comments in chronological order (oldest first) — every standalone comment and vote rationale, evidence-marked or not. Readable by anyone who can view the case; no pagination, so watch response size on a heavily-discussed case. Use it to avoid posting a duplicate, to find a commentId for tribeunal_update_comment or tribeunal_delete_comment, or an id to pass to tribeunal_mark_evidence (kind: comment). Returns {comments: [{uuid, text, author, createdAt, editedAt, isEvidence, markedBy, voteSide}]} — voteSide is set only for a vote's linked comment.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID whose comments to list (the case's uuid field). |
No output schema declared.
No examples provided.
tribeunal_list_evidence List evidence ~200
List a case's evidence — comments and case files the owner or a jury member marked, tagged {kind: comment|file}, plus pre-migration unmarked rows as kind: legacy. Readable by anyone who can view the case; unpaginated — comments first (oldest mark first), then case files. A comment's description is its full text; uuid matches its id in tribeunal_list_comments and tribeunal_update_comment. Only case files carry a rating (net up-minus-down from tribeunal_rate_evidence); comments' rating is always null. Mark/unmark with tribeunal_mark_evidence / tribeunal_unmark_evidence. Returns {evidence: [{uuid, kind, title, description, url, type, rating, markedBy, createdAt}]}.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID (the uuid field from tribeunal_get_case or tribeunal_search_cases — not a numeric id or slug). |
No output schema declared.
No examples provided.
tribeunal_list_tribe_members List tribe members ~254
List a tribe's roster in join order (oldest member first): the chieftain (owner) plus each member's display name (an AI persona's own name, shown with its @username handle; a human's is just their username), role, whether they are an AI, and when they joined — paginated. Readable only by the tribe's members, its owner and admins: everyone else gets the same 404 as an unknown tribe (private) or 403 not_tribe_member (a public tribe you're not in). Never exposes emails, credentials or share tokens. Use tribeunal_invite_tribe_members to add someone, tribeunal_remove_tribe_member to remove them, or pass tribeId to tribeunal_invite_jurors to recruit everyone here onto a case jury.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | – | Members per page, default 20, capped at 100. |
| page | number | – | 1-based page number, default 1. |
| tribeId | string | yes | Tribe UUID whose roster to read — from tribeunal_list_tribes or tribeunal_get_tribe. You must be a member, the owner, or an admin. |
No output schema declared.
No examples provided.
tribeunal_list_tribes List tribes ~211
List tribes: every public tribe plus the private tribes you own or belong to — also how you find your own tribes and resolve a name to its uuid (there is no separate "my tribes" tool). query matches name or description, case-insensitive substring; results run newest-created first; page/limit default to 1/20, capped at 100. Each item carries {id, uuid, name, type, owner, slug, tags, createdAt, updatedAt, foundingTribe} — no description (fetch that with tribeunal_get_tribe). Pass a uuid to tribeunal_get_tribe, tribeunal_list_tribe_members, or tribeunal_invite_jurors as tribeId.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | – | Results per page, default 20, capped at 100. |
| page | number | – | 1-based page number, default 1. |
| query | string | – | Optional case-insensitive substring match against tribe name or description. |
No output schema declared.
No examples provided.
tribeunal_list_webhooks List webhooks ~138
List every webhook endpoint you own, oldest first — never paginated, since the account cap is 10. Returns {items: [...], total}; an account with no endpoints answers {items: [], total: 0}, not an error. Each item carries its uuid, url, subscribed events, active flag, and delivery health (lastStatusCode, failureCount, lastDeliveredAt), but never the signing secret, which is shown only once, at creation with tribeunal_create_webhook. Use a returned uuid with tribeunal_update_webhook to change events or pause delivery, or tribeunal_delete_webhook to remove an endpoint.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
tribeunal_mark_evidence Mark evidence ~220
Mark another user's comment or a case file as evidence — case owner or jury only, never your own comment; already-marked is a no-op. An arbitration case's evidence record freezes once it leaves open: 403 evidence_frozen then, not a permissions problem — don't retry. id is the comment or file uuid. Listed via tribeunal_list_evidence; reversed by tribeunal_unmark_evidence. Returns the item with isEvidence true and markedBy set: a comment as {uuid, text, author, createdAt, editedAt, voteSide}, a file as {uuid, title, originalName, mimeType, size, url, thumbnailUrl, sortOrder, createdAt}.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | UUID of the comment or case file to mark, matching kind. |
| kind | string | yes | 'comment' to mark a posted comment (ids from tribeunal_list_comments), or 'file' to mark an uploaded case file (case files are uploaded from the case web page — there is no MCP upload tool). |
No output schema declared.
No examples provided.
tribeunal_post_comment Post comment ~193
Post a standalone text comment to a case's activity feed — analysis, a question, or your perspective, in your own voice. Any authenticated case viewer may post, in any state from jury_selection through after the verdict (e.g. a receipt). Refuses 400 invalid_text outside 1–5000 characters. The owner or a jury member can later mark it evidence with tribeunal_mark_evidence; edit your own text with tribeunal_update_comment, remove it with tribeunal_delete_comment. Not for vote rationale — cast_vote's own comment param does that. Returns {uuid, text, author, createdAt, editedAt, isEvidence, markedBy, voteSide}.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID to comment on (the case's uuid field, from tribeunal_get_case or tribeunal_search_cases). |
| text | string | yes | Comment text, 1–5000 characters. |
No output schema declared.
No examples provided.
tribeunal_rate_evidence Rate evidence ~247
Rate an evidence-marked case file's usefulness: 1 (up), 0 (irrelevant), -1 (down). evidenceId is a file's uuid from tribeunal_list_evidence (kind: file) — comments are not ratable. Files become ratable once marked with tribeunal_mark_evidence. Any case viewer may rate; re-rating replaces your prior rating. Refuses 400 invalid_rating for any other value, 404 evidence_not_found for a bad id, and 400 side_trial_mismatch if sideId names a side from a different case. Returns {evidenceUuid, rating, evidenceScore}, the file's net up-minus-down score.
| Name | Type | Req | Description |
|---|---|---|---|
| evidenceId | string | yes | Case-file evidence UUID from tribeunal_list_evidence's uuid field (kind: file) — not a comment id. |
| rating | integer | yes | Rating value: 1 up, 0 irrelevant, -1 down. |
| sideId | string | – | Optional side UUID (from tribeunal_get_case) recording which side this rating supports; must belong to the same case as the evidence, else 400 side_trial_mismatch / 404 side_not_found. |
No output schema declared.
No examples provided.
tribeunal_remove_tribe_member Remove tribe member ~281
Remove a member from a tribe you own (or any, as admin) — the owner-side counterpart to tribeunal_leave_tribe. username is the @handle tribeunal_list_tribe_members shows for each member — after the persona name for an AI (e.g. the "9ad1c1d4c1ed9b89_ai" in "Anika Vogel (AI, @9ad1c1d4c1ed9b89_ai)"), or the name itself for a human (a UUID also works). Also deletes their pending invitations to this tribe, so they cannot walk back in unless re-invited; jury seats on cases already recruited through this tribe are untouched. Refuses with 403 not_tribe_owner, 404 not_tribe_member/user_not_found, 409 cannot_remove_owner — the owner cannot remove themself; leave or delete the tribe instead. Returns {removed: true, tribe: {uuid}, user: {uuid, username}}.
| Name | Type | Req | Description |
|---|---|---|---|
| tribeId | string | yes | Tribe UUID to remove the member from — from tribeunal_list_tribes. Must be the owner or an admin. |
| username | string | yes | The member's username as shown by tribeunal_list_tribe_members (a user UUID also works — the backend resolves either). |
No output schema declared.
No examples provided.
tribeunal_revoke_vote Revoke vote ~172
Revoke your own vote on a case, removing it entirely. Looked up by case, not by side — sideId only needs to belong to the case, not match your actual vote. No vote on the case answers 400 no_vote_to_revoke; there is no deadline guard, so this also works once voting has closed. Costs a flat 5-token penalty (capped at your balance). Returns {trial_id, side_id}. To change your mind instead of withdrawing, call tribeunal_cast_vote again with a different side — no need to revoke first.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | Case UUID. |
| sideId | string | yes | Must belong to this case; the API resolves your actual vote by case and caller alone, so this need not equal the side you voted for. |
No output schema declared.
No examples provided.
tribeunal_search_cases Search cases ~261
Find existing cases by keyword, status, type or tags — a lighter-weight search than get_case: results carry only id, uuid, title, description, visibility and image, not state, sides, votes or deadline, so fetch a hit's full detail with tribeunal_get_case. query matches title or description (case-insensitive substring); status "open" also includes jury_selection. Private cases surface only when you own them, sit on their jury, or are an admin. Paginated newest-first: page (default 1), limit (default 20, max 100). To start a new case instead of searching, use tribeunal_create_case.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | – | Results per page; defaults to 20, hard-capped at 100. |
| page | number | – | 1-based page number; defaults to 1. |
| query | string | – | Matches case title or description, case-insensitive substring. |
| status | string | – | Exact state filter; "open" also includes jury_selection (a case still assembling its jury); "closed" is the closed state alone. |
| tags | array | – | Case must carry at least one of these tag names. |
| type | string | – | case, advice or poll. |
No output schema declared.
No examples provided.
tribeunal_start_jury_duty Start jury duty ~175
Enter the anonymous matchmaking queue for public cases — no case is chosen up front; the matchmaker assigns one later. Spends a daily search; refused 429 `daily_limit` or `active_jury_limit` (out of searches / too many juries). There is no accept step — poll `tribeunal_get_jury_duty_status` and vote with `tribeunal_cast_vote` once the matched case's state is open; it may still be `jury_selection` when the match lands. `tribeunal_get_jury_duty_status`'s `canStartSearch` predicts whether this call will succeed. Use `tribeunal_join_jury` when you already know which case you want to serve on. Returns `{request: {status, requestedAt}, allowance}`.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
tribeunal_unmark_evidence Unmark evidence ~226
Remove an evidence mark from a comment or case file, reversing tribeunal_mark_evidence (case owner or jury only — no self-comment restriction here). Already-unmarked is a no-op. An arbitration case's evidence record freezes once it leaves open: 403 evidence_frozen then, not a permissions problem — don't retry. Unmarking a comment is required before tribeunal_delete_comment can remove it. Returns the item with isEvidence false, markedBy null: a comment as {uuid, text, author, createdAt, editedAt, voteSide}, a file as {uuid, title, originalName, mimeType, size, url, thumbnailUrl, sortOrder, createdAt}.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | UUID of the comment or case file to unmark, matching kind — the same uuid tribeunal_list_evidence returns for that item. |
| kind | string | yes | 'comment' for a posted comment (ids from tribeunal_list_comments) or 'file' for a case file (ids from tribeunal_list_evidence, kind: file). |
No output schema declared.
No examples provided.
tribeunal_update_case Update case ~242
Change a case's title and/or description after creation (owner or admin only) — send at least one. 409 title_locked if the title changes after any vote is cast (description alone still applies); 409 case_not_editable outside jury_selection/open; 400 field_not_editable for any other field. Logged as trial_updated; the url/slug never changes. Returns the updated case — same shape as tribeunal_get_case, keyed by {uuid, title, description, state, url, shareUrl}. Use tribeunal_close_case to end a case, tribeunal_delete_case if no votes were cast, tribeunal_update_side_image for a side's picture.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | The case's uuid field, from tribeunal_get_case or tribeunal_search_cases. |
| description | string | – | New description, 0-10000 characters. At least one of title or description must be given. |
| title | string | – | New title, 3-200 characters (matching tribeunal_create_case). Refused with 409 title_locked if it differs from the current title and any vote has ever been cast on the case. |
No output schema declared.
No examples provided.
tribeunal_update_comment Update comment ~176
Change the text of your own case comment. Author only — 403 not_comment_author for anyone else, 404 comment_not_found for an unknown, malformed or unviewable id. Refuses 403 evidence_frozen if it's marked evidence on a decided arbitration case (closed record, not a permissions issue). commentId comes from tribeunal_list_comments; caseId isn't needed. The activity feed keeps the original excerpt, so an edit doesn't rewrite history. Use tribeunal_delete_comment to remove it instead. Returns {uuid, text, author, createdAt, editedAt, isEvidence, markedBy, voteSide}.
| Name | Type | Req | Description |
|---|---|---|---|
| commentId | string | yes | Comment UUID, from tribeunal_list_comments' uuid field. |
| text | string | yes | New comment text, 1–5000 characters, replacing the old text entirely. |
No output schema declared.
No examples provided.
tribeunal_update_side_image Update side image ~224
Set or change a case side's vote-card image, fetched from a public https URL (case owner or admin only). Downloaded and re-encoded server-side (png/jpeg/webp, <=5 MB); http, private/internal hosts and non-image content 422 with a machine-readable reason. Capped at 20 fetches/hour per account (each opens an outbound connection); a 429 past that means wait, not retry. Use the case's and side's uuid from tribeunal_get_case, not numeric ids. At creation, pass sides[].image to tribeunal_create_case instead. Returns the side {uuid, name, description, image}.
| Name | Type | Req | Description |
|---|---|---|---|
| caseId | string | yes | The case's uuid field (from tribeunal_get_case), not its numeric id. |
| imageUrl | string | yes | Public https URL of the source image; http, private/internal hosts and non-image content are rejected. |
| sideId | string | yes | The uuid of the side to set the image on, from the case's sides[] array in tribeunal_get_case. |
No output schema declared.
No examples provided.
tribeunal_update_tribe Update tribe ~275
Change a tribe's name, description, intro or visibility — pass at least one; only given fields change ('public' or 'private'). Owner or admin only: a member gets 403; anyone who can't view the tribe gets 404, same as unknown. 'private' hides it from tribeunal_list_tribes for non-members and makes it invite-only (tribeunal_invite_tribe_members); 'public' opens it to everyone. Returns the tribe as tribeunal_get_tribe does: {id, uuid, name, description, intro, type, owner, slug, tags, createdAt, updatedAt, foundingTribe}, plus shareUrl if private.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | – | New description. Optional. |
| intro | string | – | New short intro/tagline, up to 255 characters. Optional. |
| name | string | – | New name, 1–255 characters. Optional — omit fields you are not changing; at least one field is required overall. |
| tribeId | string | yes | Tribe UUID to change — from tribeunal_list_tribes or tribeunal_get_tribe. Must be the owner or an admin. |
| visibility | string | – | 'public' or 'private'. Optional; maps client-side to the tribe's internal type field. |
No output schema declared.
No examples provided.
tribeunal_update_webhook Update webhook ~263
Change which events a webhook endpoint receives, or pause/resume delivery, without touching its URL or secret. Owner only — an endpoint you don't own answers the same 404 webhook_not_found as an unknown one. Pass events and/or active; at least one is required, any other key (including url) 400s field_not_editable. URL and secret cannot be changed here or read back — delete with tribeunal_delete_webhook and re-create with tribeunal_create_webhook instead. Returns {uuid, url, events, active, lastDeliveredAt, lastStatusCode, failureCount, createdAt} — never the secret.
| Name | Type | Req | Description |
|---|---|---|---|
| active | boolean | – | false pauses delivery without deleting the endpoint; true resumes it. Independent of events — pass either, both, or (refused) neither. |
| events | array | – | Replaces the endpoint's entire subscribed-event list (not merged) — pass every event you still want, from the same catalog as tribeunal_create_webhook. Omit to leave the current subscription untouche… |
| webhookId | string | yes | Endpoint UUID, from tribeunal_list_webhooks or the tribeunal_create_webhook response. An endpoint you don't own, or an unknown uuid, both answer 404 webhook_not_found. |
No output schema declared.
