Convex MCP unable the find the CONVEX_DEPLOYMENT key on Cursor
Hi all. I'm making my first steps with Convex MCP so perhaps I'm just making a silly mistake. I have followed to tutorial (https://stack.convex.dev/convex-mcp-server) on how to setup the convex mcp. (the convex server is enable and lit up green). I'm using gemini-2.5-pro.
Then my first query was: "hey, can you look at the inferred schema in my convex deployment and see if I have any redundant fields?"
To this, the response was: "It looks like there's no CONVEX_DEPLOYMENT environment variable set. This is needed to connect to your Convex backend."
I, then, indicated that there is a
The documentation mentions the "status" tool that should help the model to query which deployment it has access to. Maybe there is something extra I should do related to the status tool I'm not aware of? Apologies if this is a silly misunderstanding on my part.

Convex now supports a powerful MCP server that lets you introspect your deployment's state, run functions, and read and write data.
