How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- The endpoint enforces authorisation, advertised via RFC 9728 protected-resource metadata. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability0
- Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http. See how to fix → View diagnostics → Unverified
Schema Quality & AI Usability0
- Schema blocked by authentication: the endpoint requires auth we don't have to read it. See how to fix → Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0

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 →
optionality_account_statement Account statement ~181
Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs. This is the patron's spending account — not the operator's Authority tax balance. Free — no credits consumed. Proof of npub ownership is required to prevent statement-scraping of arbitrary patrons.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Number of days of daily usage history to include (default 30). |
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| npub | string | yes | The patron's Nostr public key (npub1...). |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_account_statement_infographic Account statement infographic ~181
Generate a visual SVG infographic of your account statement. Returns the same data as account_statement, rendered as a dark-themed SVG graphic with balance hero, metrics cards, health gauge, tranche table, and tool usage breakdown. Costs 1 api_sat per call. Proof is verified by ``debit_or_deny`` before any cost is incurred.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Number of days of daily usage history to include (default 30). |
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| npub | string | yes | The Nostr public key (npub1...) whose statement to render. |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_adoption_status Adoption status ~132
Check this operator's adoption-request status at a chosen Authority. Free. Polls the Authority MCP-to-MCP for the status of this operator's request (pending / approved / rejected / provisioned).
| Name | Type | Req | Description |
|---|---|---|---|
| authority_npub | string | yes | The npub of the Authority the request was sent to. |
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_ask_tip Ask for a clue ~248
Get a non-spoiler Socratic hint for an open journal entry.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |
| entry_id | string | yes | UUID of the caller's journal entry whose scenario the question is about. |
| history | string | – | Optional JSON-encoded array of prior ``{question, answer}`` turns from this clue conversation, so follow-on questions have context. The wheel caps it hard, so oversupplying gains nothing. |
| npub | string | – | The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it. |
| question | string | yes | The trainee's question, in free text. An empty or oversized question gets a canned nudge with no LLM call. |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_check_authority_balance Authority balance ~73
Check this operator's tax balance at the Authority. Returns the sats available for certifying patron credit purchases. When this balance reaches zero, patron top-ups cannot be certified and the operator must call purchase_credits on the Authority. This is the operator's own funding — not a patron balance. Free.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
optionality_check_balance Check balance ~167
Check a patron's credit balance at this operator. This is the patron's spending balance — credits purchased via Lightning for tool calls at this operator. For the operator's own balance at the Authority (needed to certify patron purchases), use authority_check_balance instead. Free — no credits required. Proof of npub ownership is required to prevent anyone-with-the-registry from enumerating balances.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| npub | string | yes | The Nostr public key (npub1...) whose balance to check. |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_check_payment Check payment ~153
Check the payment status of a Lightning invoice. Call after paying the invoice from purchase_credits. Free — no credits required. Proof of npub ownership is required to prevent credit-grant front-running by an observer of the invoice ID.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| invoice_id | string | yes | The invoice ID returned by purchase_credits. |
| npub | string | yes | The Nostr public key (npub1...) that purchased the invoice. |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_check_price Check price ~247
Preview the effective cost of a tool call. Shows the base cost and any constraint effects (discounts, free trials, surge pricing). Free — no credits required.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| npub | string | – | Optional patron npub; with it, the preview includes that patron's coupons and constraint effects. |
| tool_id | string | yes | Either the tool's UUID (from the pricing model) or a bare capability string (e.g. ``"deal_scenario"``). FE callers usually have the capability name; this resolves both so the FE doesn't need to deriv… |
| tool_kwargs | string | – | Optional JSON object with tool call parameters for ad valorem / categorical-multiplier pricing preview (e.g. '{"amount_sats": 5000}' or '{"difficulty": "sovereign", "mode": "live"}'). |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_check_proof_status Check proof status ~172
Check whether a proof grant is still valid. Mirrors ``check_oauth_status`` for the npub-proof flow: a calling agent can ask "will my next paid call accept this dpop_token?" before burning credits on a guaranteed failure. Expiry is read from the grant itself; the only store consulted is the patron's revocation watermark. Free, no side effects — touches no relay.
| Name | Type | Req | Description |

optionality_deal_scenario Deal a scenario ~466
Generate a fresh options trading scenario and open a journal entry.
| Name | Type | Req | Description |
|---|---|---|---|
| difficulty | string | yes | ``apprentice`` | ``journeyman`` | ``adept`` | ``sovereign`` for a fresh opportunity; ``mulligan`` only paired with replay_entry_id. |

| mode | string | yes | ``historical`` | ``fiction`` | ``live`` — controls how the Firm grounds the scenario. ``live`` uses the provider's web_search tool and costs more tokens. |
| npub | string | – | The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it. |

Structured output declared, but exposes no named fields.
No examples provided.
optionality_delete_coupon Delete coupon ~146
Delete a coupon. Cascades to all patron redemptions. Any chain step referencing the deleted coupon_id becomes a no-op (the constraint returns neutral on unknown ids) — the Studio surfaces orphan references as warnings. RESTRICTED to operator — requires proof.
| Name | Type | Req | Description |
|---|---|---|---|
| coupon_id | string | yes | The id of the coupon to delete (from list_coupons). |
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |
Structured output declared, but exposes no named fields.

| npub | string | – | The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it. |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_delete_operator_credential Delete operator credential ~266
Remove a single operator secret field. Deletes one key from the operator's encrypted credential blob without touching the others — the field-level counterpart to ``forget_credentials``, which wipes the whole row. Use it to retire a leftover after an SDK cutover (a Prefect key after Modal, or a stored but untemplated orphan like ``anthropic_api_key``) without taking the operator down for a full re-delivery. Stored-but-untemplated fields are first-class: the delete is keyed on what is vaulted, not on what the current template declares. Idempotent — already-absent fields report ``removed: false`` without rewriting the vault. RESTRICTED to the operator — requires the operator's proof (a kind-27235 event or a proof grant); patron proofs are rejected. A deletion is as destructive as a write.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| field | string | yes | The operator credential field to remove (templated or not). |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_delete_patron_credential Delete patron credential ~143
Remove a single patron credential field. Deletes one field from stored credentials without affecting other fields. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |

| npub | string | yes | The patron's Nostr public key (npub1...). |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_escrow_nsec Escrow an nsec ~262
Deposit a freshly-generated nsec for operator-managed Nostr signing. Trade-off: sovereignty for UX. Optionality holds the nsec encrypted in Neon (AES-256-GCM, key derived from operator nsec). Until you withdraw it, the operator can sign Nostr DMs on your behalf. Use this only for fresh game-persona keypairs — never for an existing Nostr identity that lives elsewhere. The nsec MUST derive to the same npub that authenticated this call, or the deposit is rejected.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |

Structured output declared, but exposes no named fields.
No examples provided.
optionality_fetch_judgement Collect a judgement ~222
Redeem a judge_trade claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the judge_trade response (``entry_id`` + ``evaluation``). ``expired`` means the claim is unknown or its result aged out — submit the trade again.
| Name | Type | Req | Description |
|---|---|---|---|
| claim_check | string | yes | The ``claim_check`` string that judge_trade returned. |
| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |

| Name | Type | Req | Description |
|---|---|---|---|
| claim_check | string | yes | The ``claim_check`` string that ask_tip returned. |
| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |

Structured output declared, but exposes no named fields.
No examples provided.
optionality_forget_coupon Forget coupon ~163
Remove a coupon from this patron's redemption list. Cosmetic only — the coupon itself still exists at the operator, and the patron can re-redeem the same code later while the window allows. Free — requires proof of ``npub``.
| Name | Type | Req | Description |
|---|---|---|---|
| coupon_id | string | yes | The id of the redeemed coupon to remove (from list_my_coupons). |
| dpop_token | string | – | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| npub | string | yes | The patron's Nostr public key (npub1...). |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_forget_credentials Forget credentials ~154
Delete vaulted credentials for a specific service and npub. For operator credentials, pass the operator's own npub. For patron credentials, pass the patron's npub. Always requires proof of npub ownership — a deletion is as destructive as a write.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |

| service | string | yes | The credential service to forget. |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_get_api_usage_stats LLM usage stats ~326
Aggregated LLM usage and cost for this patron's calls. Returns ``{"models": [{"model", "runs", "total_calls", "total_input_tokens", "total_output_tokens", "total_cost_usd", "priced_runs"}, ...], "totals": {...}}``. One row per distinct model the patron's tool calls have invoked. ``total_cost_usd`` is what the PROVIDER reported for those calls, not a figure reconstructed from a price table — tokens from two models are not comparable money, so a local table goes wrong the moment the route changes model. ``priced_runs`` says how many of ``runs`` carried a reported cost, so a caller can render "$0.42 across 3 of 5 runs" rather than implying the rest were free. ``totals.avg_cost_usd`` is what one call actually costs to serve — the number that says whether a tool's sats price covers its own compute.
| Name | Type | Req | Description |

optionality_get_nostr_profile Nostr profile ~102
Read an npub's public Nostr profile (NIP-01 kind-0 metadata). Free, no proof — the data is already public on relays. Returns the latest metadata fields (name, display_name, about, picture, banner, nip05, website, lud16) or an empty profile if none is published.
| Name | Type | Req | Description |
|---|---|---|---|
| npub | string | – | The Nostr public key (npub1...) whose profile to read. |
Structured output declared, but exposes no named fields.

optionality_get_operator_onboarding_status Operator onboarding status ~57
Report this operator's configuration readiness. Shows which operator settings are configured, which are missing, and how to deliver each missing value. For patron-level credential status, use get_patron_onboarding_status instead. Free.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
optionality_get_patron_credential_fields Patron credential fields ~192
List stored patron credential field names (not values). Returns the names of fields stored for a patron, plus each field's ``delivered_at`` ISO-8601 timestamp when known (null for secrets vaulted before timestamps were recorded). Values are never exposed — use this to verify which fields are configured and how old each one is. Free. Proof of npub ownership is required: the list of configured fields is itself sensitive (reveals which integrations a patron has set up).
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |

Structured output declared, but exposes no named fields.
No examples provided.
optionality_get_patron_onboarding_status Patron onboarding status ~169
Report a patron's credential readiness for this operator. For set-once services (eXcalibur, TheBrain), shows which patron secrets are configured and which are missing. For dynamic/OAuth2 services (Schwab), reports that no patron credentials are needed. Free. Proof of npub ownership is required because credential presence is sensitive information about the patron's setup.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |

Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
optionality_get_shared_entries Shared entries of a peer ~137
List a target patron's shared evaluated entries — newest first. Public, free read: anyone (including guests) can browse the trades a leaderboard peer has chosen to share. Eager-loads the evaluation and trade proposal so the FE can render the full assessment with no follow-up call. No npub/proof envelope — this is a bootstrap-style tool the FE invokes without identity injection.
| Name | Type | Req | Description |
|---|---|---|---|

Structured output declared, but exposes no named fields.
No examples provided.
optionality_list_canonical_identities Tool identities ~250
Return canonical (tool_id, mcp_name, …) for every tool the wheel exposes. The authoritative source for any client (Studio, agents, FE) that needs to know how this MCP identifies its tools. Reconcile uses this output to UUID-join against the stored pricing model — no name-based UUID derivation, no guessing. Includes both ToolIdentity-seeded tools and any UUID recorded by ``@paid_tool`` that is missing from the registry. The latter appear with ``registered: false`` (and in the top-level ``unregistered`` array) so Reconcile can flag deploy drift instead of silently reporting clean when a live tool was never seeded (#174). If the operator renames a function or rebrands a slug, the mcp_name in this output changes but tool_id stays. That's the whole point of the canonical-UUID design. Also diffs the live FastMCP wire surface against the registry. Tools exposed on the wire but absent from the registry appear in ``unregistered`` so Reconcile can flag deploy drift instead of silently under-reporting (issue #175). Free, no side effects.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
optionality_list_constraint_types Constraint types ~51
List all available constraint types and their parameter schemas. Returns the type, category, description, and parameter specs for every constraint that can be used in a pricing pipeline. Free — no credits required.

optionality_list_coupons Coupons ~122
List every coupon this operator has minted (newest first). Each row carries the current ``times_redeemed`` counter — the Studio renders a progress bar from this against ``total_uses``. RESTRICTED to operator — requires proof.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |
Structured output declared, but exposes no named fields.
No examples provided.
optionality_list_journal List journal entries ~352
Server-side sorted, grouped, paginated list of the caller's journal. Sorting and grouping are done in SQL, so each page is a slice of the fully-ordered dataset. Returns ``{total, page, page_size, groups, entries}``; ``groups`` carries per-group counts over the whole set.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |

List the coupons this patron has redeemed on this operator. Returns both active and exhausted redemptions with a per-row ``status`` (``active`` / ``window_closed`` / ``patron_limit`` / ``total_limit``). Free — requires proof of ``npub``.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |

Structured output declared, but exposes no named fields.
No examples provided.
optionality_mint_coupon Mint coupon ~279
Create a new operator-owned discount coupon. The coupon owns its binding: ``tool_ids`` names the tools it discounts, and re-pricing a tool never touches it. A coupon bound to no tool discounts nothing, however many patrons redeem it.
| Name | Type | Req | Description |
|---|---|---|---|
| discount_percent | number | yes | Percentage off the base price (0-100). |
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |

| tool_ids | – | – | The tools this coupon discounts — tool ids or MCP tool names, or ``["*"]`` for every tool priced above zero. |
| total_uses | – | – | Aggregate cap across all patrons (default None = unlimited). |
| uses_per_patron | – | – | How many tool calls one patron can claim the discount on (default 1; pass null/None for unlimited within the window). |
| valid_from | string | yes | ISO-8601 datetime when the coupon becomes active. |

Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
optionality_publish_nostr_profile Publish Nostr profile ~150
Publish a CLIENT-SIGNED kind-0 profile to relays for an npub. The wheel never holds a patron nsec. The frontend signs the kind-0 metadata event with the patron's session key or a NIP-07 extension and passes the signed event (JSON) here; the wheel verifies the signature matches the npub, then relays it to public relays. The signature is the authorization — no proof token, no key custody. Free.
| Name | Type | Req | Description |
|---|---|---|---|
| npub | string | – | The patron's Nostr public key the event must be signed by. |
| signed_event | string | – | A JSON-encoded, client-signed kind-0 event. |

optionality_receive_credentials Receive credentials ~354
Pick up credentials from the Secure Courier. Completes the CREDENTIAL-DELIVERY flow (the ownership-proof counterpart is ``receive_npub_proof``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response you want with ``(sender_npub, service, dpop_token)`` and the tool drains ONLY the rendezvous relay that channel was pinned to. Every popped DM with the wrong session phrase is deleted and its sender is NACK'd; the first DM with the matching phrase is accepted (ACK'd) and the scan stops. If none match, the queue is drained and a ``courier_not_found`` result is returned. Do NOT poll, loop, or retry. If a credential_card (ncred1...) is provided, it is redeemed directly without any relay access (dpop_token not required for that path). On success, the payment processor client is reinitialized from the new credentials — no server restart needed.

| sender_npub | string | – | Required. The npub that sent the credentials. |
| service | string | – | Required. The credential service name (must match the service used in request_credential_channel). |
