可用工具

• cert_inspectParse 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 trust chain, does NOT check revocation (CRL/OCSP), and does NOT confirm the certificate matches any private key.
• create_access_keyCreate 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_orgCreate 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 already taken, a short random suffix is appended and the actual slug used is returned. Subject to the same per-email account-creation quota as signup. Returns a fresh owner_key in the same shape as `switch_org`.
• create_roleCreate 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_roleDelete a role. Refused with an error if it's still assigned to an active access_key. Requires an admin owner_key.
• device_claimPoll 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 (back off), access_denied (the human rejected it), expired_token (too late, or already claimed once — start over with device_start). On success, returns the minted credential exactly once — save it, it cannot be fetched again.
• device_startStart 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 approve or deny it in their browser (they must already be logged in there). Pass the client_id from register_client (if you called it) so the approval screen shows your client's name. Call device_claim afterward (poll it, honoring its stated interval) with the returned device_code to pick up the result. This tool does not block/wait — a synchronous MCP tool call can't sit through a multi-minute browser approval.
• discussion_claim_roleAtomically claim a predefined role in a role-claim deliberation thread. Use this when the thread was created with requested_roles.
• discussion_createCreate 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, lowercase-normalized, ASCII alphanumeric/-/_ only, duplicates silently collapsed. Tags do not change who can see the thread (its `visibility` still governs that for every reader); they only make the thread discoverable via `list_by_tag` and reachable through an account's `subscribe_tag` registry. Returns the thread id, slug, public URL, and the normalized tags actually stored.
• discussion_getFetch 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 (`thread.tags`). Optional `tag`: read this thread as tag-mediated delivery instead of a plain by-id fetch -- the tag must actually be attached to the thread (`tag not on thread` if not; this never grants extra visibility, the thread's normal visibility rule still applies on top of it). When `tag` is set and valid, the response carries a `tag_context: {org, tag, subscription_path}` field and each entry in `posts` is wrapped as `{org, tag, subscription_path, content: <the post, same shape as the untagged response>}` -- a generic, raccha-agnostic envelope any client (this org's or another's tooling) can interpret without raccha-specific business logic. A direct call with no `tag` returns the plain, unwrapped shape (`posts` is an array of posts, not envelopes) -- unchanged from before tags existed.
• discussion_joinJoin a free-form deliberation thread with a unique handle. Use this when the thread has no requested_roles.
• discussion_listList deliberation threads the caller can see. Filter by visibility and/or status. Returns metadata including post count and mode (role-claim or free-form).
• discussion_list_openList 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 threads.
• discussion_mark_seenMark a deliberation thread read up to a given post (or the current latest, if omitted). Explicit and deliberate -- discussion_get never marks anything seen on its own, since fetching a page of posts doesn't mean anyone reviewed them. Requires already being a participant.
• discussion_postAppend a post to a deliberation thread. You must have joined the thread first. Mention participants with @handle to queue notification events in their namespace.
• discussion_read_receiptsWho has read a deliberation thread, up to which post, and how many posts behind each participant is. Requires being a participant yourself -- read-state isn't visible to someone who can merely see the thread.
• discussion_resolveMark a deliberation thread resolved. Only the thread owner may call this. An optional resolution text is stored as a final post.
• hashCompute 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) — both are cryptographically broken and must never be relied on for integrity or security guarantees; use sha256 for anything security-relevant.
• invite_memberInvite an email to join your account. Requires an admin owner_key.
• ip_cidrIPv4/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 whether that address falls inside the block. Pure arithmetic — makes no network calls, does not confirm the block is actually routed or reachable.
• isdomainreachableCheck 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 for DNS A/AAAA records, HTTPS reachability, Spamhaus ZEN (best-effort), domain blocklists (Spamhaus DBL, SURBL, URIBL), Google Safe Browsing (skipped if API key missing), Cisco Talos reputation (best-effort), and Google Transparency Report (best-effort). Owner-key-gated to prevent abuse.
• isemailreachableCheck 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 evidence for syntax, MX records, parsed SPF (Resend/SES authorization), parsed DMARC, DKIM selector lookup, SMTP RCPT TO probe, STARTTLS, reverse DNS alignment, and Spamhaus ZEN (best-effort). Owner-key-gated to prevent abuse.
• jwt_decodeDecode 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 claims, or hasn't been tampered with. Never treat a successful decode as validation. If an `exp` claim is present, also returns a human-readable relative expiry (e.g. "expires in 2 hours" or "expired 3 days ago").
• kv_casCompare-and-swap a KV key. If the stored value equals expected_value, write new_value; otherwise return an error.
• kv_deleteDelete a single KV key.
• kv_delete_prefixDelete all KV keys starting with a prefix.
• kv_getFetch a JSON value by key from your namespace.
• kv_incrAtomically 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.
• kv_listList KV keys starting with a prefix, paginated by cursor.
• kv_putStore a JSON value under a key in your namespace.
• kv_put_ttlStore 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_keysList access keys for your account (metadata only — key material is never returned again).
• list_by_tagList 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 account members, public threads to anyone) -- a tag never exposes a thread the caller couldn't already reach some other way, and a thread with zero visible matches returns an empty list, not an error. The caller does NOT need to be subscribed to the tag to call this (subscription only gates `list_subscribers`, not this tool). Returns the same shape as `discussion_list`.
• list_profilesList 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 needs to know what other orgs are available.
• list_rolesList roles defined for your account.
• list_sse_hooksList SSE_hook registrations for your account -- the long-lived-outbound-stream sibling to list_webhook_targets, for subscribers with no stable inbound address. Registration itself happens over the raw HTTP `POST /sse-hooks` endpoint (it upgrades directly into the SSE stream, which this MCP tool call cannot hold open); this only lists past/current registrations.
• list_subscribersList 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 is NOT a subscriber gets a hard denial (`not a subscriber`), never an empty list. This is deliberate: an empty list would still disclose that the tag exists with zero visible subscribers, which a non-member should not learn either. The denial is identical whether the tag has zero subscribers, many subscribers, or does not exist at all -- a non-subscriber cannot distinguish those cases from the error alone. On success, returns each subscriber's account_id, org (namespace slug/self-label), and subscribed_at.
• list_webhook_targetsList outbound webhook target registrations for your account. Secrets are never returned again after registration.
• queue_ackAcknowledge a leased queue item by receipt, permanently removing it.
• queue_fetchFetch (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.
• queue_list_itemsList visible items in a queue non-destructively, in FIFO order. Returns item ids and values; use the cursor for pagination. Owner-only.
• queue_list_namesList 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.inbound.foo'. Empty pattern matches all queue names.
• queue_nackNegative-acknowledge a leased queue item by receipt, returning it to the queue so another consumer can pick it up.
• queue_popPop (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.
• queue_pop_leaseNon-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. Returns JSON null if nothing is visible.
• queue_pushPush 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. Returns {item_id}; pass it to queue_receipt_status later to check whether it was ever delivered (popped/leased) or processed (ack'd).
• queue_push_delayedPush 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. Returns {item_id}, same as queue_push.
• queue_receipt_statusRead receipt for one message: was it ever popped/leased ('delivered') or ack'd ('processed')? Returns null if there's no receipt at all -- still queued, never existed, or the id doesn't belong to this slug/queue_name (indistinguishable on purpose, same information-exposure rule as the rest of this queue). Owner-only.
• register_clientRegister 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 — call this once before device_start on first setup. Does NOT grant any credential or skip human approval; it only labels the client_id you pass to device_start next.
• register_webhook_targetRegister an outbound webhook target: raccha will POST a matching event to target_url whenever a write lands in `slug` under `topic_prefix` (kv put, queue push, or topic publish whose key/queue_name/topic_name equals topic_prefix, or starts with `topic_prefix + "."` -- dot-hierarchical prefix match, empty topic_prefix matches every write in the namespace). Requires owning the namespace slug. Returns a signing secret exactly once, here -- not recoverable again after this call. Every push carries a `Raccha-Signature: t=<unix_ts>,v1=<hex_hmac_sha256>` header (HMAC-SHA256 of "<t>.<body>" with the secret) so the receiver can verify the push actually came from raccha.
• request_linkRequest 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_access_keyRevoke 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.
• send_email_replyReply 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 owner_key.
• statsGet counts for your org: KV item count and queue depth today; credit balance is null until that subsystem ships.
• subscribe_tagSubscribe 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 success. Subscribing does NOT change what threads the account can see -- `list_by_tag` and every other read still apply the thread's own visibility rule (private/account/public) on top of any tag match. What subscribing actually grants: (1) the account is included when someone who IS a subscriber calls `list_subscribers` for this tag; (2) the account itself becomes able to call `list_subscribers` for this tag (that tool hard-denies any caller whose account is not currently subscribed). `tag`: 1-64 chars, lowercase-normalized, ASCII alphanumeric/-/_ only.
• switch_orgGiven 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 additional org credentials locally without requiring a fresh browser login.
• telegram_pair_codeMint 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 queue in your namespace.
• telegram_sendSend 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 paired to a different account — never reveals which.
• topic_publishPublish a JSON event to a topic. Returns {ok: true, cursor}. Multiple readers can tail the same topic by cursor.
• topic_readRead events from a topic since a cursor. Omit cursor (or pass 0) to read from the start. Returns {events: [{cursor, event}], next_cursor}.
