As of November 13, 2026, musedirectory.ai tracks 6537 connectors for Meta Muse. 6351 of 6492 remote endpoints (98%) passed their latest health check, with a median response time of 303ms. Our scout has checked 43,700 public MCP servers from the official MCP Registry; 40,610 answered, 193 failed safety screening, and 3,813 were useful enough to list (11% of those fully screened).

Health comes from an MCP initialize sent to every endpoint every 15 minutes. Scout numbers come from reading every remote server in the official MCP Registry, connecting to it, and screening it as described in the method. Raw data: /api/stats.
What the kinds mean. "In the Muse app" covers connectors Meta built itself and third-party connectors Meta lists inside Muse, which you turn on in a tap. "Announced" means Meta named the partner publicly but the connection may not be switched on yet. "Third-party" means a public MCP server that works in Muse when you add it as a custom connector; Meta says it does not review custom connectors, so we screen each one for safety before listing it. "Live" means the server answered a standard MCP handshake at its last check. Connectors that do not have a public endpoint (most built by Meta) are counted but not health-checked.
