LMCP Not Connecting — Fix in 30 Seconds

LMCP is installed but not responding? Here are the three things that fix it in almost every case.

You installed LMCP and it worked — but now your AI assistant says it's not connected, or the menu bar icon is gone. This happens for a few predictable reasons, all with a quick fix.


Fix 1 — Re-run the install command (fixes 90% of cases)

The install command is safe to re-run. It starts the tray if it stopped, reconnects Cloud Relay, and doesn't touch your config or data.

curl -fsSL https://local-mcp.com/install | bash

After running it, look for the LMCP icon in your menu bar (top-right of your screen, near the clock). The dot should turn green within a few seconds.


Fix 2 — Restart LMCP from the menu bar

Click the LMCP icon in the menu bar → Restart LMCP (near Settings). That reloads the app after an update or if tools stopped responding. If you were prompted to restart your AI client as well, quit and reopen Claude Desktop or Cursor after LMCP is back (green dot).


Fix 3 — Start the tray manually

If you prefer not to re-run the install, you can start the tray app directly:

  1. Open FinderApplications → double-click Local MCP
  2. The LMCP icon should appear in your menu bar within a few seconds
  3. Click the icon — the dot should be green (connected)

If the dot stays orange, click the icon → Cloud RelayConnect.


Fix 4 — After a Mac restart

LMCP uses a LaunchAgent to start automatically at login. If it didn't start after a reboot, run this in Terminal to reload it:

launchctl load ~/Library/LaunchAgents/com.local-mcp.tray.plist

Then check for the LMCP icon in your menu bar.

If that file doesn't exist, the LaunchAgent may have been removed. Re-running the install command (Fix 1 above) will restore it.


Still not working?

Check the LMCP logs for clues:

tail -50 ~/Library/Logs/LocalMCPTray.log

If you see an error you don't understand, paste it into Claude with the question: "I'm trying to fix my LMCP setup, here's the error:" — Claude can usually diagnose it from the log line.

You can also send feedback from inside the tray: click the LMCP icon → Send Feedback. We read every report.
