bluesky-mcp

An MCP (Model Context Protocol) server for managing a Bluesky account from Claude (or any MCP-compatible client): post, reply, like, repost, follow/unfollow, search, and read your timeline/notifications. Uses the official AT Protocol API with a handle + app password — no OAuth app, no approval process required, and works even with 2FA enabled since it never touches your real account password.

The original one-off post.js CLI script is still here and still works if you just want to fire off a single post from the terminal without going through Claude.

Setup

1. Clone the repo and install dependencies:

   git clone https://github.com/AhmadTariq1337/bluesky-mcp.git
   cd bluesky-mcp
   npm install
   

2. Copy .env.example to .env and add your handle + app password (get an app password from Bluesky: Settings → Privacy and Security → App Passwords):

   cp .env.example .env
   

3. Register it as an MCP server in your client's config. For Claude Desktop (claude_desktop_config.json):

   "bluesky": {
     "command": "node",
     "args": ["/absolute/path/to/bluesky-mcp/index.js"]
   }
   

4. Restart Claude Desktop (fully quit from the tray, not just close the window) so it picks up the new server.

Tools exposed

For the "un-" actions, pass the AT-URI of the record itself (the like/repost/follow record, returned in viewer.like / viewer.repost / viewer.following on posts and profiles) — not the original post or account's URI.

Standalone CLI (no Claude needed)

node post.js "Just shipped a new project, check it out!"

(npm run post-cli -- "text" works the same way.) Prints a link to the live post. 300 character limit, checked before sending.

Security

• .env holds your real handle and app password, and is gitignored — never commit it.
• App passwords are scoped and revocable from Bluesky's settings, unlike your main account password.
