mcp-lighthouse

Lighthouse MCP

A Model Context Protocol (MCP) server that enables Claude to interact with your Lighthouse.one portfolio data. This integration allows you to query and analyze your crypto portfolio directly through Claude.

Features

• Authentication: Securely authenticate with Lighthouse using transfer token URLs
• Portfolio Overview: Get detailed breakdowns of your portfolio including:
  • Total portfolio value
  • Asset type distribution
  • Major holdings (≥ $1,000)
  • List of connected wallets/accounts

Usage with Claude Desktop

Add this to your claude_desktop_config.json:

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

When running this mcp-lighthouse server locally make sure to point to the correct build output.

{
  "mcpServers": {
    "lighthouse": {
      "command": "path/to/node/installation",
      "args": ["path/to/this/folder/mcp-lighthouse/dist/index.js"]
    }
  }
}

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

Authentication Walkthrough

To authenticate with Lighthouse, follow these steps:

• Go to the Settings page on Lighthouse.one
• Click on "Link Mobile Device" option
• Click on "Copy transfer link"

Note: The URL will be in the format of a Lighthouse transfer token URL which Claude can use to authenticate your session.

Available Commands

Once connected, you can use the following commands with Claude:

• Authenticate

  Use the authenticate command with a Lighthouse transfer token URL to log in.
  

• Get Portfolio Overview

  Use the getLighthousePortfolio command to view your current portfolio status.
  

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

NOTE: You can always revoke the session key from the Lighthouse dashboard.

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.
