Smart Proxy (daedalus)

Token-efficient MCP gateway that uses semantic vector search to route tool calls across multiple upstream servers, reducing prompt token consumption.

Aggregates multiple upstream MCP servers behind a two-tool interface (list and search) that uses vector embeddings to match natural-language queries to the right tool. Supports ChromaDB, Qdrant, and pgvector backends for the semantic index, with pluggable embedding providers including local sentence-transformers and OpenAI. Includes a CLI with serve, index, status, and validate commands, dynamic upstream loading via directory watching, and both stdio and SSE transports.
