Download Local MCP for Claude Desktop

macOS · notarized universal binary — runs the same local server as the DMG, no Node or terminal required

How to install

  1. 1Click the download button above. Your browser saves a file named local-mcp.mcpb.
  2. 2Double-click the file. Claude Desktop opens with an install dialog.
  3. 3Click Install. The extension appears in Settings → Extensions and Claude can immediately call any of the 201+ tools.
  4. 4The first time Claude calls a tool that needs it, macOS will ask permission (Calendar, Contacts, Mail…). That's normal — Local MCP runs on your machine.

Link this computer to your account

Installed with npx or the .mcpb extension, LMCP starts without an account. Linking it takes a minute:

  1. When this computer is not linked yet, LMCP’s answer in your AI app includes a link. It works once, within 30 minutes.
  2. Open the link in your browser. It goes to My LMCP.
  3. In the browser, sign in to your LMCP account, or create one.
  4. Check the computer’s name and click Link this computer. If LMCP asks, approve on that computer too.
  5. The computer is then listed in My LMCP, and its tool calls count toward your account.

Open My LMCP

Troubleshooting

Double-click does nothing
Make sure Claude Desktop is installed and has been opened at least once. Then drag the .mcpb file onto the Claude Desktop window.
Download button fails or MCPB registry is down
The installer file is served directly from LMCP — you do not need the public MCPB registry. Retry download or use the full macOS installer.
I want auto-update, the menu bar Tray, or to use Local MCP from Cursor / ChatGPT
Use the full installer instead — it includes the Tray app, LaunchAgent, auto-updates and the cloud connector. Download the macOS installer.

LMCP as a plugin or a connector, by AI client

LMCP is one MCP server, and each AI client has its own word and install path for it. Install the LMCP app first: its tools run on your computer.

LMCP in Claude.ai and Claude Desktop: a connector

In Claude’s chat apps LMCP is a connector, and Claude Desktop can also install it as a desktop extension.
