Connect munge to your agent

One MCP endpoint, ten public-data sources, OAuth or API-key auth. Connect Claude, Cursor, or any MCP-compatible client in under a minute.

Setup

The fastest path: let Claude Code register itself via OAuth.

claude mcp add --transport http munge https://munge.sh/mcp

Claude will open a browser window for you to sign in. Once approved, the munge tools become available — no copy-paste, no keys to manage.

Using an API key

For clients that don't speak OAuth (Cursor, Cline, custom code):

  1. Go to your dashboard → API keys → Generate.
  2. Copy the key — it's shown once.
  3. Pass it as Authorization: Bearer <key> on every MCP request.
