How to uninstall Local MCP completely

On a Mac, one command removes LMCP and everything it set up; on Windows, Settings → Apps does the same. Two entries are yours to remove: an npx entry you added by hand and a connector in ChatGPT or Claude.ai.

Uninstall LMCP

  1. On a Mac: quit LMCP from the menu bar, then run curl -fsSL 'https://local-mcp.com/uninstall' | bash in Terminal.
  2. On Windows: open Settings → Apps, select LMCP (Local MCP Server) and choose Uninstall.
  3. If you added LMCP as a connector to ChatGPT or Claude.ai, remove it there: Claude.ai under Customize → Connectors, ChatGPT at chatgpt.com/plugins.
  4. If you added npx -y local-mcp@latest to an MCP client by hand, delete that entry from the client’s settings.

On a Mac

Quit LMCP from the menu bar, then run the uninstaller in Terminal:

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

Dragging the app to the Trash removes the app but keeps this computer’s identity, so a later install is the same computer; the uninstaller removes the identity too.

On Windows

Open Settings → Apps, select LMCP (Local MCP Server) and choose Uninstall.

What uninstalling removes

On Mac and on Windows, uninstalling removes:

  • the app and its programs
  • what starts LMCP on its own: the LaunchAgent on Mac, the startup shortcuts on Windows
  • LMCP’s settings and logs
  • the permissions you saved, such as tools you always allow, and on Mac the privacy permissions you granted LMCP
  • your recipes
  • this computer’s identity: its ID and the keys and tokens kept in the Mac Keychain or the Windows Credential Manager
  • LMCP’s entry in Claude Desktop, Cursor and the other AI apps it had configured

What remains is a small .uninstalled marker, so a leftover copy does not start again: on Mac in ~/.local/share/local-mcp and ~/Library/Application Support/Local MCP; on Windows in %LOCALAPPDATA%\local-mcp-uninstalled, with nothing left in %LOCALAPPDATA%\local-mcp. If something cannot be removed, such as an identity in a locked Keychain, the uninstaller says so.

If you use npx

The uninstaller removes the entries LMCP configured itself. If you added npx -y local-mcp@latest to an MCP client by hand, that entry belongs to the client: delete it from the client’s MCP settings.

ChatGPT and Claude.ai

The uninstaller cannot reach ChatGPT or Claude.ai. If you added LMCP there as a connector, remove it in Claude.ai under Customize → Connectors and in ChatGPT at chatgpt.com/plugins. Until then it stays listed but no longer reaches your computer.

Frequently asked questions

Does uninstalling LMCP remove everything?

Yes, except a small .uninstalled marker that stops a leftover copy from starting again. On Mac and on Windows it removes the app, what starts it on its own, its settings and logs, the permissions you saved, your recipes, this computer’s identity with its keys in the Mac Keychain or the Windows Credential Manager, and LMCP’s entry in the AI apps it had configured.

Is dragging LMCP to the Trash enough on a Mac?

No. It removes the app but keeps this computer’s identity, so a later install is the same computer. The uninstaller removes the identity and everything else.

How do I uninstall LMCP on Windows?

Open Settings → Apps, select LMCP (Local MCP Server) and choose Uninstall. It removes the same things as on a Mac, with the identity’s keys in the Windows Credential Manager.

I use LMCP through npx. How do I remove it?

Delete the npx -y local-mcp@latest entry from your MCP client’s settings. The uninstaller removes the entries LMCP configured itself; an entry you added by hand is yours to remove.

Do I need to remove LMCP from ChatGPT or Claude.ai?

Yes, if you added it there as a connector: the uninstaller cannot reach them. Remove it in Claude.ai under Customize → Connectors and in ChatGPT at chatgpt.com/plugins. Until then it stays listed but no longer reaches your computer.
