Model Context Protocol
Bring your tools to Mystical.
Publish an MCP server once, and it's usable by every Mystical user — in Chat, and in Cospace tasks that run on their own.
Publish once
One registration, every Mystical user
List your MCP server in the catalog and it works the same way for anyone who connects it — no separate integration for Chat versus Cospace.
Bring your own MCP server
Register the URL, write the sentence someone reads before connecting it, and submit it for review. Once it's approved, it's in the catalog every Mystical user can browse.
Register a connector- One URL to register. We connect to it to check it speaks MCP.
- Reviewed by a person before it goes live.
- Unpublish any time without cutting off people already connected.

From a URL to the catalog
Four states, and you can see which one a listing is in at any point from the connectors page.
- 1
Register
Give us the server URL. We connect to it right then to confirm it speaks MCP and to see how it authenticates.
- 2
Describe it
Write the sentence someone reads before deciding to hand your server access to their account. It's the part review looks at hardest.
- 3
Submit for review
A person reads what the server actually does. Tool descriptions become instructions inside someone else's model context, so this is a real step rather than a formality.
- 4
Published
It's in the catalog. Anyone can find and connect it, and you can unpublish later without breaking the people who already did.
