The Universal Tool Calling Protocol (UTCP) is a secure, scalable standard for defining and interacting with tools across a wide variety of communication protocols. UTCP 1.0.0 introduces a modular core with a plugin-based architecture, making it more extensible, testable, and easier to package.

In contrast to other protocols, UTCP places a strong emphasis on:

• Scalability: UTCP is designed to handle a large number of tools and providers without compromising performance.
• Extensibility: A pluggable architecture allows developers to easily add new communication protocols, tool storage mechanisms, and search strategies without modifying the core library.
• Interoperability: With a growing ecosystem of protocol plugins (including HTTP, SSE, CLI, and more), UTCP can integrate with almost any existing service or infrastructure.
• Ease of Use: The protocol is built on simple, well-defined Pydantic models, making it easy for developers to implement and use.
