How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Compabase to help me. It is a free service with an MCP server at https://compabase.com/api/mcp. It needs an API key from ContentWriterco; ask me to enter it through your secure credential prompt. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- request_signup: Start Compabase account setup for an email. Sends a magic link. After the user clicks it, poll check_signup with the returned setup_id until status is ready — then you receive an MCP key automatically. Do not ask the user to generate a key in the portal. No auth required.
