- count_recordsCount the total records in an account's collection (e.g. how many likes a user has given). Scans server-side so you don't page manually. AT Protocol has no cheap exact count, so for very large collec…
- count_repos_by_collectionCount how many accounts across the network publish a given collection/lexicon,e.g. 'how many accounts have an at.glean.subscription?'. Walks a relay's com.atproto.sync.listReposByCollection with NO p…
- describe_pdsDescribe a Personal Data Server: its DID, whether registration requires an invite, the handle domains you can register there, and ToS/contact links. Works for any PDS, not just Bluesky. Input is the …
- get_account_historyAn account's history from its PLC audit log: handle changes, PDS migrations, signing-key rotations, and creation time. did:plc accounts only (did:web has no PLC log). Input is a handle or DID.
- get_app_linkTurn an at:// URI (or handle/DID) into shareable web links,a Bluesky/Blacksky app URL to open in a browser, plus the canonical PDS getRecord URL. Use when the user wants a clickable/pasteable link.
- get_backlinksIndex of who/what references a target,the inbound likes, reposts, quotes, replies, and follows,as COUNTS per category, via the Constellation backlink index. Target is a record's at:// URI or an accou…
- get_blob_infoGet metadata for a single blob: its canonical PDS getBlob URL plus a best-effort content-type and byte size (via a HEAD request). Returns the URL, never the bytes. Use to turn a blob ref (CID) found …
- get_did_documentFetch the raw DID document for any DID or handle: all aliases (alsoKnownAs), every service entry (PDS, labeler, custom AppView), and verification methods. Broader than get_profile, and works for did:…
- get_latest_commitThe current head commit of an account's repository (com.atproto.sync.getLatestCommit): its commit CID and revision. The cheapest way to fingerprint a repo or detect whether it changed since you last …
- get_pds_directory_infoA cached health card for a PDS from pds.directory: version, DID, approximate user count, reachability, last-checked time, available domains, and which relays index it. Input is the PDS hostname (e.g.…
- get_profileGet an account's repository overview (handle, DID, PDS, and the list of collections it contains). Input is a handle or DID.
- get_recordFetch a single record by its full at:// URI (must include collection and rkey). Returns the record's value, CID, and resolved identity.
- get_relay_directory_infoA cached overview of a relay from firehose.directory: counts of PDSes it indexes (total/active/offline/banned) and total accounts. Input is the relay hostname (e.g. bsky.network). Best-effort/cached …
- get_repo_statusLiveness/moderation status of an account's repository: whether it is active, its current revision, and any takedown/suspended/deactivated/deleted state. Answers 'has @alice been taken down?' which ge…
- get_threadReconstruct the conversation around a post: its ancestor chain up to the thread root (following reply.parent, root-first) PLUS a bounded descendant reply TREE,replies, replies-to-replies, and so on, …
- list_backlink_recordsList the actual records (author DID + verified handle + at:// URI, newest first) that reference a target for ONE category,i.e. WHO liked, reposted, quoted, replied to, mentioned, or follows it. Workf…
- list_blobsList the blobs (uploaded media/attachments,images, video, etc.) hosted in an account's repository, via com.atproto.sync.listBlobs. Returns each blob's CID and its canonical PDS getBlob URL (PDS-nativ…
- list_labelersList the labeler (moderation) services known to the labeler relay,each labeler's DID, resolved handle, and service endpoint. The discovery step BEFORE query_labels, which needs a labeler DID/handle u…
- list_recordsList records in a collection for an account, with pagination. Provide the repo (handle or DID) and the collection NSID (e.g. app.bsky.feed.post).
- list_reposList the accounts (repositories) hosted on a PDS, via com.atproto.sync.listRepos: each repo's DID and active/takedown status, paginated. Answers 'who is hosted on this PDS?' / 'how many accounts does…
- list_repos_by_collectionNetwork-wide: which accounts publish a given collection/lexicon,e.g. 'who has an app.bsky.feed.generator (a custom feed)?' or who uses a custom lexicon. Via a relay's com.atproto.sync.listReposByColl…
- query_labelsWhat moderation labels a labeler has applied to a subject (com.atproto.label.queryLabels),e.g. 'has @alice or this post been labeled spam/nsfw/hidden by labeler X?'. Anonymous and service-agnostic: t…
- resolveResolve any AT Protocol identifier to JSON. Accepts an at:// URI (at://<did-or-handle>/<collection>/<rkey>), a bare handle (alice.bsky.social), or a DID (did:plc:...). Returns a profile, a collection…
- resolve_lexiconExplain what a record type means by resolving its lexicon schema. Input is a collection NSID (e.g. app.bsky.feed.post). Returns the schema's description and definition.
- search_accountsSearch for AT Protocol accounts by handle or display name (paginated, via the Bluesky AppView app.bsky.actor.searchActors, so accounts unknown to that index may be missing). Returns candidate account…
- search_lexiconsBrowse or search the registry of published AT Protocol lexicon schemas. The response's `total` field is the exact registry size and `matched` is the exact match count. Substring matches the NSID or d…
- verify_handleBidirectionally verify that a handle is really owned by its DID, via DNS TXT and HTTPS well-known. Returns whether each method passed. Use this to check for impersonation/spoofing,search results and …
