This is actually caused by a whole swathe of Cursor bugs, which I’m told are being worked on.

New MCP bugs on non-stdio MCP servers

Auto-reconnection to MCP servers is broken (runs multiple times in parallel, then fails). on/off works OK

Where does the bug appear (feature/product)? Cursor IDE Describe the Bug When cursor detects a change to mcp.json (i.e. when we edit it), it auto-reconnects, but it incorrectly calls its own auto-reconnect code 3 times in parallel, all at the same time, then errors out. Toggling off/on works OK.
