@-reply discovery of MCP servers

Hey all!!

I’m digging through the documentation and I can’t find how to make my MCP servers discoverable inline in chat.

I’m able to discover things like booking’s MCP server by starting with @booking, and I’m wondering if I’d be able to make my custom MCP servers discoverable that way too (say, I could try typing @sgo.to (my MCP server lives at code.sgo.to)).

Any chance that’s supported openly? Or is this just available to selected apps?
