AuthMCP Gateway

Secure authentication proxy for Model Context Protocol (MCP) servers

AuthMCP Gateway is a full MCP protocol proxy with centralized authentication, authorization, and monitoring. It transparently proxies all MCP capabilities — tools, resources, prompts, and completions — from multiple backend servers through a single authenticated endpoint.

OAuth + DCR ready: the gateway supports OAuth 2.0 Authorization Code flow with Dynamic Client Registration (DCR), so MCP clients like Codex can self-register and authenticate without manual client provisioning.
