MCP Gateway: What It Is and the Real Options in 2026
An MCP gateway is a reverse proxy that sits between AI clients like Claude Desktop, Claude Code, or Cursor and multiple MCP servers, exposing them all through a single endpoint while adding authentication, tool filtering, secrets management, and observability. Instead of configuring ten servers in every client, you configure one gateway once. As of July 2026 the main open-source options are Docker MCP Gateway, IBM's ContextForge, agentgateway, MetaMCP, and Unla, with Kong and Zuplo covering the managed enterprise end. This guide explains when a gateway earns its place in your stack, compares the real options, and walks through a verified Docker MCP Gateway setup.
