# MCP server

Connect any Model Context Protocol client to `https://www.chicagopolitics.org/mcp` (Streamable HTTP). Clients that support OAuth ask you to sign in; others can send an API key as a Bearer token.

## Connect

In clients configured with JSON, the entry usually looks like this:

```json
{
  "mcpServers": {
    "chicago-politics": {
      "url": "https://www.chicagopolitics.org/mcp",
      "headers": { "Authorization": "Bearer cp_live_..." }
    }
  }
}
```

Leave out `headers` if your client signs in with OAuth.
