Activitypub Mcp

Overview

Activitypub Mcp is a read-only-by-default MCP server that lets language models explore the Fediverse, including Mastodon, Misskey, and Pleroma. Any MCP-compatible AI assistant can call its tools directly, with the model deciding when to use them during conversations or agent runs.

The server runs locally via the npm package activitypub-mcp, which communicates over stdio on your machine. No authentication is required—it works out of the box. Version v3.2.1 is available now under the MIT license, with full source code at cameronrye/activitypub-mcp on GitHub.

Activitypub Mcp is listed in the AI & Agents category on mcp.site and is compatible with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed.
