The Kong Rate Limiter MCP Server is available on Docker Hub as `shibbirmcc/kong-ratelimiter-mcp-server`.

#### Host Configuration

By default, the server binds to `127.0.0.1`, which works for local development but may not be accessible when running in Docker. For Docker deployments, especially on Windows, you might need to bind to `0.0.0.0` to allow external access:

```bash
# Run with custom host binding
docker run -p 8080:8080 -e FASTMCP_HOST=0.0.0.0 shibbirmcc/kong-ratelimiter-mcp-server
```

#### Quick Start with Docker Hub
