As MCP becomes the standard protocol for AI agents to interact with tools, teams are running dozens of MCP servers — filesystem, GitHub, databases, Slack, search, and more. Managing them is chaos:

• Every AI client connects to every server independently
• No central authentication or access control
• No visibility into which tools are being called, by whom, and how often
• No rate limiting to prevent runaway agents from hammering your APIs

mcp-gateway solves this. It sits between your AI clients and your MCP servers, acting as a single, observable, secure entry point.
