Connects Claude to a Postgres-backed behavioral oracle for Rust crate APIs with 66 million probe records across datetime, crypto, encoding, and JWT operations. Exposes five tools: signature search by type shape, behavior lookup for specific functions showing actual input/output tables, cross-implementation comparison tables, deprecation resolution, and routing for general API questions. No LLM generation in responses, just deterministic SQL and bge-m3 embedding retrieval. Useful when you need runtime behavior data instead of documentation claims, or want to see how chrono versus time actually handle the same duration string. Free tier at 10k requests per day, no signup.
