mcp-server-qdrant

Rust MCP server for Qdrant with local BERT embeddings. Single binary, no Python.

Why not the official Python one?

ONNX Python wheels are painful to package in Nix (especially aarch64-linux). This is a Rust rewrite with Nix-native packaging and a pure-Rust default backend (Candle) that has zero native dependencies.
