UTCP

Overview of UTCP

UTCP (Universal Tool Calling Protocol) is a lightweight, secure standard that enables AI agents and applications to discover and call tools directly using their native protocols without requiring wrapper servers. This innovative protocol eliminates the complexity of traditional integration approaches that force developers to build and maintain wrapper servers for every tool, route traffic through middleman protocols, and accept additional latency. UTCP acts as a comprehensive manual that tells agents exactly how to call your tools directly, following the core philosophy: if a human can call your API, an AI agent should be able to call it too – with the same security and no additional infrastructure requirements. The protocol is particularly valuable for developers working with AI APIs & SDKs and those building AI Agents & Assistants.

UTCP extends OpenAPI for AI agents while maintaining full backward compatibility, adding agent-focused enhancements like tags for categorization, average_response_size for resource planning, multi-protocol support, and direct execution instructions. This makes it ideal for tool providers who want to expose their REST APIs to AI agents, SaaS providers looking to make their services AI-accessible, and enterprise teams enabling internal tool usage by AI systems. The protocol supports multiple communication methods including HTTP, CLI, gRPC, MCP, and more, providing unprecedented flexibility for AI Automation Platforms and integration scenarios.

How to Use UTCP

Getting started with UTCP involves a straightforward three-step process that can be completed in about five minutes. First, install the UTCP library using your preferred package manager. Next, expose your first tool by creating a UTCP manual that describes how AI agents should interact with your API or service. Finally, call your tool directly through the UTCP client, which handles discovery, learning, and execution. The workflow follows a natural progression: agents fetch your UTCP manual, understand how to call your tools, make direct calls using native protocols, and receive normal responses from your API without any intermediary layers or performance overhead.

Core Features of UTCP

1. Zero Latency Overhead – Direct tool calls eliminate proxy servers and middleman protocols
2. Native Security Integration – Leverage existing authentication and authorization systems
3. Multi-Protocol Support – Compatible with HTTP, CLI, MCP, GraphQL, and custom protocols
4. OpenAPI Compatibility – Extends OpenAPI specifications with AI agent enhancements
5. Plugin Architecture – Extensible system supporting custom protocols and tool repositories

Company Info

UTCP is developed as an open standard for universal tool calling protocol, focusing on enabling seamless integration between AI agents and various tools through direct protocol communication. The project maintains an active community presence through GitHub and Discord, with ongoing development and specification improvements driven by community contributions and real-world implementation feedback.

Login and Signup

As UTCP is primarily a protocol specification and implementation library rather than a hosted service, there are no traditional login or signup requirements. Developers can access the protocol through official GitHub repositories and package managers, with implementation details available in the comprehensive documentation and quick start guides provided by the UTCP community.
