Introducing UTCP - The Direct Alternative to MCP

· 3 min read

We're excited to introduce the Universal Tool Calling Protocol (UTCP) — a modern, flexible, and scalable standard for defining and interacting with tools across a wide variety of communication protocols.

Why UTCP?​

While the Model Context Protocol (MCP) has made strides in standardizing AI-tool interactions, it comes with inherent limitations that UTCP addresses head-on:

🚀 Zero Latency Overhead​

Unlike MCP's proxy-based architecture, UTCP enables direct tool calls without intermediary layers. Your AI agents communicate directly with tools, eliminating unnecessary latency.

🔒 Enhanced Security​

UTCP's design principles prioritize security from the ground up. With direct protocol support and built-in authentication mechanisms, you get enterprise-grade security without compromising performance.

🌐 Protocol Flexibility​

While MCP is limited to specific transport mechanisms, UTCP works seamlessly across:

  • HTTP/HTTPS
  • GraphQL
  • gRPC
  • WebSockets
  • CLI interfaces
  • Custom protocols

Key Features​

Direct Tool Integration​

// Example: Direct HTTP tool call with UTCP
const weatherTool = {
  name: "get_weather",
  description: "Get current weather for a location",
  provider: {
    type: "http",
    endpoint: "https://api.weather.com/v1/current",
    method: "GET"
  },
  parameters: {
    location: { type: "string", description: "City name" }
  }
}

Universal Protocol Support​

UTCP isn't bound to a single communication method. Whether your tool speaks HTTP, GraphQL, or even CLI commands, UTCP can handle it:

# GraphQL Tool Definition
name: user_search
provider:
  type: graphql
  endpoint: https://api.example.com/graphql
  query: |
    query GetUser($id: ID!) {
      user(id: $id) { name email }
    }

Built-in Authentication​

Security is paramount. UTCP supports multiple authentication methods out of the box:

{
  "auth": {
    "type": "bearer",
    "token": "${API_KEY}"
  }
}

Getting Started​
