Activitypub

ActivityPub MCP is a Model Context Protocol (MCP) server that enables large language models (LLMs) like ChatGPT and Claude to interact with the Fediverse via ActivityPub and WebFinger. It provides a full-featured, secure, and typed interface for LLMs to read from and write to Fediverse timelines, post, reply, boost, and follow accounts, without the need to self-host an ActivityPub instance. The tool is designed for developers, AI enthusiasts, and anyone wanting to empower LLMs with direct, structured access to federated social networks.
