MCP Gateway

One gateway between your AI and every tool it needs, without flooding the context window.

MCP Gateway is a single Rust binary that sits between an AI client and all of its tools. Connect MCP servers and REST APIs behind it, and the agent sees a compact meta-surface of 9 to 17 tools instead of every backend definition. It discovers and calls backend tools on demand. A small live-agent benchmark found no completed-task token saving from that extra hop, so the value is catalog capacity plus policy and routing—not a blanket token claim. See Benchmarks.

Personal and noncommercial use is free, including running the full gateway. Running it commercially needs a commercial license.

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 moves the full catalog out of the exposed tool list. The agent loads a small fixed set of meta-tools, searches with gatewaysearchtools, and invokes a backend tool with gateway_invoke. This creates room for larger catalogs, but the extra search hop can cost more tokens and time on a completed task.

Shortened. The full README is on GitHub.
