MCP Gateway is a single Rust binary that sits between an AI client and all of its tools. Connect any number of MCP servers and REST APIs behind it, and the agent sees only a compact meta-surface of 14 to 16 tools instead of hundreds of tool definitions. It discovers and calls the right backend tool on demand. On a 100-tool stack that is about 89% less context-token overhead per request in the README benchmark, and the answer to \"how many tools can I connect\" becomes \"unlimited.\" Personal and noncommercial use is free, including running the full gateway. Running it commercially needs a commercial license, and only a small MIT core of generic building blocks is MIT-licensed. The problem this removes Every MCP tool an AI client connects costs roughly 150 tokens of context overhead, loaded into every request whether the tool gets used or not. Connect 20 servers with 100 tools between them and you spend about 15,000 tokens before the conversation starts. Context limits then force a second cost: you have to decide up front which tools to connect and leave the rest out, so the agent makes worse decisions because it cannot reach data you chose not to load. MCP Gateway removes both costs. The agent loads a small fixed set of meta-tools, searches the full catalog with gateway search tools , and invokes any backend tool with gateway invoke only when it needs it.
