Custom MCP not available to agent

Hey, thanks for the report. I can see the screenshot. Stitch is in mcp.json, but the agent isn’t picking it up.

This looks like a couple of known patterns, so let’s narrow it down. Can you confirm:

  1. In Cursor Settings → Tools & MCP, does Stitch show up? If yes, is it enabled, and is the tool count greater than 0 or is it 0?
  2. If you open a new agent chat after Stitch shows as connected in Settings, do the tools appear?
  3. Which mcp.json did you edit, the global one ~/.cursor/mcp.json or the project one <project>/.cursor/mcp.json?
  4. Open Output → MCP Logs or Cursor Logs via the Command Palette and look for lines with McpProcess, ipcReady, Stitch, 0 tools. If you find anything relevant, paste it here.
  5. Does this reproduce on both OSes macOS and Linux, or only on one?

A couple similar threads just in case, maybe a workaround there helps:

Once I have the logs and answers above, it’ll be clearer where to dig next.
