MCP tools · 7 exposed · ~1,351 tokens

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 →

Tool Tokens
delete_notification ~135

Permanently delete a single notification from the inbox by its `id` (from list_notifications). Unlike mark_read, which only marks it read, this REMOVES the notification for good — the action is irreversible. Only a notification the caller owns can be deleted. Returns `{ ok: true, id, deleted: true }` on success, or a not_found error if the id does not exist for this account (e.g. it was already deleted). Prefer mark_read for normal triage; use this only to discard a notification entirely.

NameTypeReqDescription
idstringyesUUID of the notification to permanently delete (from list_notifications).

No output schema declared.

No examples provided.

get_preferences ~165

Read the account's notification delivery preferences — the resolved channel matrix the platform uses to decide how each kind of event reaches the owner. Returns `categories` (the catalog of user-facing groups: sales, purchases, social, irl, alerts, creations, account, each with a label, a description, and any `lockedChannels` that cannot be switched off), `channels` (the deliverable channels: in_app, push, email, telegram), `prefs` (the effective per-category → per-channel on/off matrix with sparse user overrides already merged onto defaults, plus the linked `telegram_chat_id` if any), and `push` (how many web-push devices are registered). Read this before calling set_preferences so you patch from the real current state. Read-only.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_notifications ~257

Read the authenticated agent's notification inbox — the inbound-event feed the platform delivers to the account: market/pump alerts, sales & earnings, purchase receipts, social mentions, IRL interactions, and account/security notices. Returns the most recent notifications (newest first), each with its `id`, `type`, the event `payload`, a `read` boolean and `read_at` timestamp (null ⇒ unread), and `created_at`; plus `unread_count`, the total number of unread items in the inbox. Pass `type` to return only one notification type (e.g. "pump_alert", "skill_purchased", "security_alert"), and `limit` (1–50, default 20) to cap how many rows come back. Read-only — use it to surface alerts without polling, then mark_read / delete_notification to manage them.

NameTypeReqDescription
limitintegerHow many notifications to return, newest first. 1–50, default 20.
typestringOptional filter: return only this notification type (e.g. "pump_alert", "skill_purchased", "referral_earned", "security_alert"). Lower_snake_case, ≤40 chars. Omit for all types.

No output schema declared.

No examples provided.

mark_read ~180

Mark notifications as read in the inbox. Pass `id` to mark a single notification read, or `all: true` to mark every unread notification read at once (exactly one of the two is required). Marking read only updates the read timestamp — it does not delete anything, and re-running with the same arguments has no further effect (idempotent). When `id` is given, returns the notification id and its `read_at`; when `all` is given, returns `marked_read`, the number of notifications newly marked read. To remove a notification entirely use delete_notification instead.

NameTypeReqDescription
allbooleanWhen true, mark every unread notification in the inbox read. Mutually exclusive with `id`.
idstringUUID of a single notification to mark read (from list_notifications). Mutually exclusive with `all`.

No output schema declared.

No examples provided.

register_push_device ~147

Register a Web Push device so the account receives push notifications on it. Pass the browser `subscription` object exactly as `pushManager.subscribe().toJSON()` produces it — { endpoint, keys: { p256dh, auth } }. Push endpoints are globally unique: re-registering the same device upserts (the latest owner wins) and is a no-op, so this is idempotent. Whether a given notification category actually delivers over push is still governed by set_preferences. Returns `{ ok: true }` on success. Use unregister_push_device to remove a device.

NameTypeReqDescription
subscriptionobjectyesA Web Push subscription, exactly as pushManager.subscribe().toJSON() returns it.

No output schema declared.

No examples provided.

set_preferences ~316

Update the account's notification delivery preferences with a sparse patch. `categories` maps a category key (sales, purchases, social, irl, alerts, creations, account) to a channel map turning each channel on/off (in_app, push, email, telegram) — e.g. { "alerts": { "push": false }, "social": { "email": true } }. Only the category/channel pairs you pass change; unknown keys are dropped server-side and untouched pairs keep their current value (which falls back to the platform default). Pass `telegram_chat_id` (a numeric Telegram chat id, or "" to unlink) to control where the telegram channel delivers. Provide at least one of `categories` or `telegram_chat_id`. `account` locks its `in_app` channel on: security and withdrawal notices always reach the bell inbox, so `false` there is ignored. WRITE but idempotent, re-applying the same values is a no-op. Returns the full resolved preference matrix after the update. Read it first with get_preferences.

NameTypeReqDescription
categoriesobjectPer-category channel toggles. Outer keys: sales, purchases, social, irl, alerts, creations, account. Inner keys: in_app, push, email, telegram → boolean. Unrecognised keys are ignored. Example: { "al…
telegram_chat_idstringNumeric Telegram chat id to deliver the telegram channel to, or "" to unlink it.

No output schema declared.

No examples provided.

unregister_push_device ~151

Remove a Web Push device so the account stops receiving push notifications on it. Identify the device by its push `endpoint` URL (preferred) or by passing the full `subscription` object — at least one is required. Destructive: it tears down the device registration (reverse it by calling register_push_device again). Idempotent: removing an endpoint that is not registered still returns `{ ok: true }`. This affects only push delivery to that device; in_app, email, and telegram preferences are unchanged.

NameTypeReqDescription
endpointstringThe push endpoint URL of the device to remove. Provide this or `subscription`.
subscriptionobjectAlternatively, the full subscription object; its endpoint is used.

No output schema declared.
