activitypub-mcp vs mimirs

activitypub-mcp: ActivityPub MCP Server is a comprehensive Model Context Protocol server that enables LLMs like Claude to explore and interact with the Fediverse. It provides over 50 tools, 10 resources, and 11 prompts for reading timelines, posting content, managing accounts, searching, and exporting data. Supports multiple platforms including Mastodon, Pleroma, and Misskey.; mimirs: Mímirs provides persistent project memory for AI coding agents, reducing token consumption and context overhead through local indexing, semantic search, cross-session memory, and dependency graphs. It works with multiple editors and is privacy-preserving with no cloud dependencies. The tool achieves 90-98% recall@10 on real codebases.
