Description

zig-utcp is a pure Zig standard library implementation of the Universal Tool Calling Protocol (UTCP) that enables seamless integration of large language models with various tools via HTTP, CLI, MCP, SSE, WebSocket, and more. It supports multiple authentication methods, tool loaders, streaming, middleware, rate limiting, caching, and testing utilities, providing a robust and memory-efficient framework for tool calling. The project offers full feature parity with Go, Rust, and TypeScript implementations, making it a versatile choice for developers working in Zig.
