Trust proxy configuration guide.', }, ] --- # Proxy Support 1MCP supports trust proxy configuration for deployment behind load balancers and reverse proxies like nginx, Apache, or Cloudflare. ## Overview When 1MCP runs behind a proxy, it needs to be configured to trust the proxy in order to correctly identify the client's IP address and the protocol (HTTP/HTTPS). This is essential for security features like rate limiting and for accurate logging. ## Configuration Trust proxy settings can be configured via the `--trust-proxy` command-line flag or the `ONE_MCP_TRUST_PROXY` environment variable. For detailed information on the available options and how to configure them in your JSON file, CLI, or environment, please see the **[Configuration Deep Dive](/guide/essentials/configuration#network-options)**. For specific examples and security considerations, refer to the **[Trust Proxy Reference](/reference/trust-proxy)**.
