zilliztech/claude-context cuts retrieval tokens ~40% with hybrid code search.

claude-context (11.8K stars) is an MCP server that indexes your whole codebase into Milvus and exposes hybrid BM25 + dense-vector search to Claude Code and any MCP agent. Ask "find functions that handle user authentication" instead of grepping. Zilliz reports ~40% token reduction at equal retrieval quality, with support for OpenAI, VoyageAI, Ollama, and Gemini embeddings. On a large repo this is the difference between the agent reading three relevant functions and dumping whole files into context.
