What is MCP Gateway?
MCP Gateway is a self-hosted gateway and proxy, shipped as a single Rust binary, that sits between an AI client such as Claude, Cursor or Codex and all of its tools. Instead of loading every tool definition into each request, the agent sees a small fixed set of meta-tools, searches for the tool it needs and calls it on demand, which saves context. It includes over 100 built-in API integrations and a wizard that imports your existing MCP servers. Personal and non-commercial use is free; commercial use needs a paid licence.
Pros
- Use many MCP servers without filling the context window
- Over 100 API integrations built in
- Self-hosted, one binary, easy import of existing servers
Cons
- Commercial use needs a paid licence
- Adds another service to set up and run
Who should use MCP Gateway
Developers who connect lots of MCP servers to Claude, Cursor or Codex and want to cut token use.
Who may not need it
People who only use one or two MCP servers.
