Add the server to your Claude Code settings (~/.claude/settings.json):

{
  "mcpServers": {
    "legal-mcp": {
      "type": "url",
      "url": "https://legal-mcp-production.up.railway.app/mcp",
      "headers": {
        "X-CourtListener-Token": "YOUR_COURTLISTENER_TOKEN"
      }
    }
  }
}

Getting a CourtListener token

1. Create a free account at https://www.courtlistener.com/sign-in/
2. Go to your profile and copy your API token
3. Add it as the X-CourtListener-Token header above

Optional: Clio practice management

If you have a Clio account with API access, add your OAuth token:

"headers": {
  "X-CourtListener-Token": "YOUR_COURTLISTENER_TOKEN",
  "X-Clio-Token": "YOUR_CLIO_OAUTH_TOKEN"
