v3.19.0-ea.1

Features

• MCP Gateway - Traefik Hub now includes MCP Gateway, a dedicated gateway for securing and governing Model Context Protocol (MCP) servers. The MCP Gateway acts as an OAuth-compliant proxy that enables organizations to centrally manage access to MCP servers, tools, and resources with Task-Based Access Control (TBAC)—a new authorization paradigm designed specifically for AI agents.

• LDAP Middleware - Added a new middleware. (hubldap) which provides LDAP authentication for the API Portal.

• Responses API Middleware -Added a new middleware that provides support for the OpenAI Responses API endpoint. The Responses API is the successor to the OpenAI Chat Completions endpoint

Improvement

• Introduce an intermediate http.Header in the responseRecorder to prevent duplicate headers in the response writer of the LLM Guard middleware
