Universal Tool Calling Protocol (UTCP) is a secure, scalable standard for defining and interacting with tools across various communication protocols. Its Python implementation features a modular core with a plugin-based architecture, enhancing extensibility and ease of use.

python-utcp sits in the API Integration category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Secure and Scalable Standard. A representative use case is Interacting with diverse APIs (HTTP, REST, GraphQL) via a unified client.. The listed license is MPL-2.0. GitHub stars are currently 653. Relevant tags include Tool Calling Protocol, Python.

This write-up is based on the project's README and public repository data. We have not hand-tested the tool.
