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.

did you have 3 cursor windows opened during this, I’ve noticed this changes wrt how many cursor windows are opened

I don’t recall presently, but I do sometimes use >1 window at the same time (and I am aware that each instance reconnects).

Hey there! A lot has changed in 2.5 with MCPs. Please try upgrading. Hopefully the issue is fixed – if not, please raise a new thread.

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