@sunsetsyntax introduced mcp-gateway, a Rust binary aimed at MCP tool schemas that can burn about 15k tokens before an agent starts working. It exposes a fixed roughly 15-tool meta-surface, then discovers and invokes backends on demand for a local, private, low-bloat setup.
Key Takeaways
- ✓A fixed ~15-tool meta-surface avoids dumping every MCP schema into context.
- ✓Backends are discovered and invoked on demand in a local private process.
- ✓Ships as a Rust binary focused on coding-agent token cost.
