UTCP
The scalable, secure alternative to MCP for tool calling
Listed in categories:
Developer ToolsOpen SourceArtificial Intelligence
Description
The Universal Tool Calling Protocol (UTCP) is an open standard that enables AI agents to call any native endpoint directly over various channels without the need for wrappers. This protocol allows for direct communication with tools' native endpoints, such as HTTP, gRPC, WebSocket, and CLI, thereby reducing latency and maintaining existing authentication, billing, and security measures.
How to use UTCP?
To use UTCP, developers can start by reading the documentation and RFC for specifications and best practices. They can prototype the protocol using the UTCP Agent or connect to existing tools using the UTCP-MCP Bridge.
Core features of UTCP:
1️⃣
Direct API calls without wrappers
2️⃣
Support for multiple communication channels (HTTP, gRPC, WebSocket, CLI)
3️⃣
Low latency access to existing APIs
4️⃣
No changes required to existing tools or infrastructure
5️⃣
Open-source and community-driven development
