One key per assistant; delete one and it stops working at once.
Your feeds' reader stats are visible to you only, and never show who reads them.
The Model Context Protocol is an open standard that lets AI assistants use tools and data from other services. bluefacts runs an MCP server, so your assistant can use bluefacts' Bluesky data.

Any client that supports remote MCP servers over HTTP, such as Claude Code, Claude Desktop, Cursor, VS Code, Codex, Gemini CLI. Clients that only run local servers can connect through mcp-remote.
With a plain sign-in it doesn't act for your account at all: it only reads bluefacts' stats, plus your own feeds' reader numbers. If you allow full access, it can also search Bluesky as you and create, edit and delete your custom feeds. None of the tools post, follow, like or read your messages.
No. You sign in through Bluesky itself, and your conversations stay with your AI assistant. bluefacts only receives the tool calls.
Up to 60 requests a minute per account. Searches count against your own Bluesky account's limits.
Sign in with Bluesky, create a key, and paste it into your assistant.
