You sign in with your ThinkOut account, the same one you use in the app, and the assistant only sees the workspaces you gave it access to. Clients that cannot sign in can send an MCP key instead.

Other clients

Any MCP-compatible client that supports Streamable HTTP can connect at the address https://mcp.thinkout.io, either by signing in or by sending an MCP key as a bearer token.

​
MCP key

Some clients cannot run the interactive sign-in. Those can authenticate directly instead: create an MCP key in ThinkOut under My account, and send it in the Authorization header.
In a client that takes its own configuration file:
An MCP key belongs to the account rather than to a person, so it reaches every workspace in the account, not only the ones you can open yourself. It keeps working until you regenerate or revoke it. Sign in instead wherever the client supports it.
