Activitypub

ActivityPub MCP is a server that enables Large Language Models (LLMs) like Claude and ChatGPT to connect to the Fediverse using the ActivityPub and WebFinger protocols, without requiring users to host their own Fediverse server. It provides a complete Model Context Protocol (MCP) interface for interacting with Fediverse accounts, posts, and users, exposing structured resources optimized for LLM integration. The tool is designed for developers and organizations integrating LLMs with federated social networks, offering features like multi-account management, secure operation, cross-platform support, and typed TypeScript implementation.
