congressmcp

Connect Claude Desktop to US Congressional data - bills, amendments, members, committees, and more.

Quick Start (5 minutes)

Installation

npm install -g congressmcp

Setup

  1. Get your API key:
    • Visit: https://congressmcp.lawgiver.ai
    • Sign up for a free account
    • Check your email for your API key
  2. Configure local MCP client:

Add this to your config or cline_mcp_settings.json with your API key:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

{ "mcpServers": { "congressmcp": { "command": "npx", "args": [ "-y", "congressmcp" ], "env": { "CONGRESSMCP_API_KEY": "your-api-key-here" } } } }
  1. Restart Claude Desktop to activate the connection.

Usage

Ask Claude about:

  • Bills: "Search for recent climate bills"
  • Members: "Who represents California in the Senate?"
  • Committees: "What committees handle healthcare?"
  • Amendments: "Show amendments to HR 1234"
  • Roll Call Votes: "How did senators vote on the infrastructure bill?"
  • And much more legislative data!

Alternative Installation: Self-Hosted

For advanced users who want full control, CongressMCP is open source:

  • Clone the CongressMCP repository
  • Requires Python environment + database setup
  • Congress.gov API key needed
  • See CongressMCP/README.md for technical details
