Refresh discovery

POST/api/w/:wid/mcp-upstreams/:uid/discover

Ask the upstream again for its capabilities and tool names. Changed tools stay hidden until an owner accepts the new manifest.

#Authentication

Session cookie

A signed-in person: the console's session cookie. Every state-changing request also carries the header x-immiscible-csrf: 1, and the member's role decides what it may do. Bearer tokens are ignored on these routes, so no machine credential can reach them.
