Universal Tool Calling Protocol (UTCP)
Communicating the interoperability between systems using AI agents.
UTCP (Universal Tool Call Protocol) is a lightweight standard that enables AI agents to discover and directly call tools, APIs, and services using their native protocols without requiring intermediary wrapper servers or additional infrastructure. It works by providing a standardized “manual” that describes how to interact with your tools - similar to how OpenAPI documents APIs for human developers, but enhanced with agent-focused features like categorization tags and multi-protocol support (HTTP, CLI, gRPC, MCP). The key innovation is that agents can read these manuals to understand how to call your existing APIs directly with their original authentication and security mechanisms intact, eliminating the latency, complexity, and maintenance burden of traditional middleware approaches while making any human-callable API instantly accessible to AI systems.
