Search posts, profiles, feeds, threads, and trending topics on Bluesky via MCP. STDIO or Streamable HTTP.
Bluesky MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Search posts, profiles, feeds, threads, and trending topics on Bluesky via MCP. STDIO or Streamable HTTP.
Once Bluesky is connected, these are the calls the assistant has available:
bsky_search_posts — Full-text search across public Bluesky posts, with author, language, tag, date, and sort filtersbsky_get_profile — Fetch a Bluesky actor's public profile by handle or DID — the handle↔DID resolverbsky_get_author_feed — A user's recent posts ordered newest-first, filterable by post typebsky_get_post_thread — Fetch the conversation for a post by AT-URI — parent chain upward and reply tree downward, with what Bluesky counted but did not returnbsky_search_actors — Find Bluesky accounts by name or handle fragmentbsky_get_follows — Paginated social graph edges — who a user follows or who follows thembsky_get_trending — Real-time trending topics on Bluesky with post count, category, status, and the accounts driving each topicPrerequisites — The Prerequisites tool exposed by this serverInstallation — The Installation tool exposed by this serverYou will need 2 environment variables: MCP_TRANSPORT_TYPE, MCP_LOG_LEVEL. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
api.bsky.app without credentials.Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Among the file and storage access options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Bluesky's toolset — bsky_search_posts, bsky_get_profile, bsky_get_author_feed and 6 more — is a fair guide to whether it matches your workflow. It is maintained by cyanheads; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
