Read-only-by-default MCP server: let LLMs explore the Fediverse — Mastodon, Misskey, Pleroma.

Install

claude mcp add activitypub-mcp -- npx -y [email protected]

Requires: ACTIVITYPUB_ENABLE_WRITES, LOG_LEVEL

Our take

A broad ActivityPub/Fediverse MCP server with read-only exploration enabled by default and mutation tools gated behind an explicit environment variable. It has real package history, tests, docs, and security notes, and the install helpers are user-invoked rather than postinstall behavior. The caveat is scope: once writes are enabled, it can post, follow, boost, block, and upload media, so clients should surface those permissions clearly.
