MCP server for Bluesky
Bluesky MCP becomes available to MCP clients through the bluesky mcp mcp server. MCP server for Bluesky.
A Model Context Protocol (MCP) server for Bluesky that can post on your behalf by using the AT Protocol.
Once connected, the assistant can call these 3 tools directly:
Authentication — The Authentication tool exposed by this serverPosts — // Get a single post tool: "get-post" params: { uri: string // The URI of the post to fetch }Interactions — // Unlike a post tool: "unlike-post" params: { likeUri: string // The URI of the like to remove }The server is distributed via npm as @smithery/cli, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
The server reads 2 environment variables: BLUESKY_IDENTIFIER, BLUESKY_PASSWORD. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Bluesky MCP sits in that group, and the shape of its toolset — Authentication, Posts, Interactions — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
