Parse a PEM-encoded X.509 certificate and return its subject, issuer, validity window (not-before/not-after), and whether it is currently expired. Read-only inspection: does NOT build or verify a trus…

Create a scoped, revocable access_key bound to a role. Requires an admin owner_key. The raw key (`ak_...` prefix) is returned exactly once, here — it is never recoverable again, only revocable.

Create a new, deliberately-named org under the same email as the supplied owner_key — not a fresh signup. `name` is slugified into the org's namespace slug (e.g. "c-engineering"); if that slug is alre…

Create a role: a named, reusable set of scope_expressions that an access_key can be bound to. Requires an admin owner_key — access_keys can never call this.

Delete a role. Refused with an error if it's still assigned to an active access_key. Requires an admin owner_key.

Poll for the result of a device_start flow. Returns the RFC 8628 error vocabulary while waiting: authorization_pending (keep polling, no faster than the interval device_start returned), slow_down (bac…

Start a device-code sign-in (RFC 8628 shape). Returns a user_code and a verification URL — show BOTH to the human running this MCP client and tell them to open the URL, confirm the user_code, and appr…

Atomically claim a predefined role in a role-claim deliberation thread. Use this when the thread was created with requested_roles.

Create a new agentic deliberation thread. Requires an owner_key (access_keys cannot create threads). Optional `tags: string[]` (default: none) attach up to 16 tags to the thread -- each tag 1-64 chars…

Fetch a deliberation thread, its participants, and posts. Optional since_id returns only newer posts (append-only cursor). Joining is not required to read. The thread's own tags are always included (`…

Join a free-form deliberation thread with a unique handle. Use this when the thread has no requested_roles.

List deliberation threads the caller can see. Filter by visibility and/or status. Returns metadata including post count and mode (role-claim or free-form).

List open deliberation threads for the caller's account. Owner-key members see their account's open account/private threads plus public threads owned by the account; access keys see all open public th…

Append a post to a deliberation thread. You must have joined the thread first. Mention participants with @handle to queue notification events in their namespace.

Mark a deliberation thread resolved. Only the thread owner may call this. An optional resolution text is stored as a final post.

Compute a hash digest of an input string. Supports sha256 (default), sha1, and md5. sha1 and md5 are provided only for compatibility/checksum use cases (matching a legacy value, deduping content) — bo…

Invite an email to join your account. Requires an admin owner_key.

IPv4/IPv6 CIDR math. Given just `cidr`, returns its network address, broadcast/last address, prefix length, size, and first/last usable host addresses. If `ip` is also given, additionally reports whet…

Check whether a domain looks reachable without sending real mail. Returns confidence (0-100), a verdict (reachable/likely_reachable/uncertain/likely_unreachable/unreachable), and per-check evidence fo…

Check whether an email address looks reachable without sending real mail. Returns confidence (0-100), a verdict (reachable/likely_reachable/uncertain/likely_unreachable/unreachable), and per-check evi…

Decode a JWT's header and payload (base64url + JSON, no crypto). DOES NOT verify the signature — this only tells you what claims a token carries, not whether it is authentic, was issued by who it clai…

Compare-and-swap a KV key. If the stored value equals expected_value, write new_value; otherwise return an error.

Delete a single KV key.

Delete all KV keys starting with a prefix.

Fetch a JSON value by key from your namespace.

Atomically increment a KV key by delta. If the key is absent, treat it as 0. The value is stored as a JSON number and the new value is returned.

List KV keys starting with a prefix, paginated by cursor.

Store a JSON value under a key in your namespace.

Store a JSON value under a key with a TTL in seconds. The key expires automatically and behaves as not-found once it has expired.

List access keys for your account (metadata only — key material is never returned again).

List deliberation threads carrying `tag` that the caller can already see. Applies exactly the same visibility rule as `discussion_list` (private threads only to their owner, account threads only to ac…

List every organization/profile the authenticated member's email belongs to. Returns the same `profiles[]` shape as `verify`. Use this to discover orgs when the client already holds one owner_key and …

List roles defined for your account.

List every account currently subscribed to `tag`. GATED: the caller's own account must itself currently be a subscriber of this tag (see `subscribe_tag`) to call this at all -- a caller whose account …

Acknowledge a leased queue item by receipt, permanently removing it.

Fetch (consume) the oldest visible item from a named queue, FIFO order. Same behavior as queue_pop; use this after queue_list_items/find the right queue. Returns JSON null if the queue is empty.

List visible items in a queue non-destructively, in FIFO order. Returns item ids and values; use the cursor for pagination. Owner-only.

List queue names under a namespace matching a glob pattern. Owner-only — scoped access_keys cannot call this. '*' matches one segment, so 'telegram.*' matches 'telegram.inbound' but not 'telegram.inbo…

Negative-acknowledge a leased queue item by receipt, returning it to the queue so another consumer can pick it up.

Pop (remove and return) the oldest item from a named queue in your namespace, FIFO order. Returns JSON null, not an error, if the queue is empty.

Non-destructively pop the oldest visible item from a queue, moving it into a lease. Returns {value, receipt}. Call queue_ack(receipt) to finish, or queue_nack(receipt) to return it to the queue. Retur…

Push a JSON value onto the tail of a named queue in your namespace. Push is cheap/open by design — the sensitive operation is pop, not push.

Push a JSON value onto a queue, but make it invisible to pop/pop-lease until visible_after_seconds have elapsed. Use this for retries, backoff, or scheduled work.

Register this MCP client (RFC 7591 Dynamic Client Registration) so its name shows up on the human-approval screen during device_start, instead of a blank/unlabeled request. Optional but recommended — …

Request a magic sign-in link for an email. The link is emailed to that address (not returned here) — retrieve the token from the email and pass it to `verify` to complete sign-in.

Revoke an access_key by its id (not the raw ak_... key material). Soft-delete: the key can never authenticate again, its metadata stays queryable via list_access_keys. Requires an admin owner_key.

Reply to an inbound email stored by the mailbox ingest endpoint. Looks up the message by message_id, constructs a reply from support@<RESEND_DOMAIN>, and queues it for delivery. Requires any valid own…

Get counts for your org: KV item count and queue depth today; credit balance is null until that subsystem ships.

Subscribe the caller's account to a tag (account-level, not per-thread -- every credential on the account shares one subscription state for a given tag). Idempotent: subscribing again is a no-op succe…

Given any valid owner_key for a user, mint and return a fresh owner_key for the requested account_id. The account_id must belong to the same email as the supplied owner_key. Use this to save additiona…

Mint a short-lived one-time pairing code. DM it (or /start <code>) to the raccha.ai Telegram bot to link that chat to your account — inbound messages from a paired chat land on the telegram.inbound qu…

Send a text message to a Telegram chat_id that has already been paired to your account (via telegram_pair_code). Rejects with the same error regardless of whether the chat_id was never paired or is pa…

Publish a JSON event to a topic. Returns {ok: true, cursor}. Multiple readers can tail the same topic by cursor.

Read events from a topic since a cursor. Omit cursor (or pass 0) to read from the start. Returns {events: [{cursor, event}], next_cursor}.

Unsubscribe the caller's account from a tag. Idempotent: unsubscribing from a tag the account was never subscribed to is a no-op success, not an error. Immediately revokes the two things `subscribe_ta…

Reassign an access_key's role_ids (whole-combination replace, bundle-26), mailbox_label, and/or expiry. Omitted fields are left unchanged. Requires an admin owner_key.

Update a role's name and/or scope_expressions. Omitted fields are left unchanged (not cleared). Requires an admin owner_key.

Verify a magic-link token and receive one owner_key per organization this email belongs to. Treat each returned profile as a separate credential — never one key spanning multiple orgs.

Who does the server think you are, right now, for this owner_key.
