Score: 8.0/10 (Innovation: 8, Technical: 8, Documentation: 9, Utility: 7)

An MCP proxy that hides large upstream tool catalogs behind five meta-tools, cutting tool-definition tokens by ~97% via hybrid BM25 + multilingual embedding search that runs in pure Go. It forwards caller auth upstream, separates read/write tools for approval flows, and validates arguments before dispatch, with honest benchmarks and evaluation sets.

Target audience: backend devs, AI/LLM application developers, DevOps running MCP gateways
