MCP Gateway Overview

MCP Gateway is a single Rust binary that consolidates multiple MCP servers and REST APIs behind one interface, exposing only a small set of meta-tools to AI clients. It dynamically discovers and invokes backend tools on demand, drastically reducing context token usage compared to connecting tools directly. Use it to scale AI tool integration without flooding the context window or preselecting tools.
