Show HN: Rs-Utcp, a Rust Implementation of the Universal Tool Calling Protocol
github.comI’ve been working on a Rust implementation of UTCP, a vendor-neutral protocol for LLM tool calling. The goal is to avoid every model/vendor defining its own schema and instead make tool ↔ model interoperability predictable and boring. What works:
- Full UTCP message parse/serialize - Strongly typed request/response model - Transport-agnostic (stdin/stdout, HTTP, WS, anything) - Minimal dependencies, straightforward API
Still to do:
- Validation helpers - Higher-level client/server wrappers - More real-world examples
