Usage with Claude Desktop

NOTE: You must have at least Node LTS installed to use this MCP server. Try N-Install to quickly install Node on your system. Add this to your claude_desktop_config.json:

 "mcpServers": {
 "lighthouse": {
 "command": "npx",
 "args": ["-y", "mcp-lighthouse"]

Then restart the Claude app. If you don't get any errors on startup, then the MCP server is working.

1. Go to the Settings page on Lighthouse.one
2. Click on "Link Mobile Device" option Lighthouse Link Mobile Device
3. Click on "Copy transfer link" Mobile Transfer Code Note: The URL will be in the format of a Lighthouse transfer token URL which Claude can use to authenticate your session.

Session Management

• The server maintains a session file (.lighthouse_session) to persist your authentication
• You only need to authenticate once unless you explicitly log out or the session expires
• Session data is stored securely on your local machine

Security Note

This MCP server runs locally on your machine and communicates directly with Lighthouse's API. Your authentication credentials are never shared with Claude or any third-party services.
