What is UTCP?
UTCP (Universal Tool Calling Protocol) is an open standard for AI agents to call tools directly, positioned as a lightweight alternative to MCP. It eliminates the "wrapper tax" for lower latency by using a simple JSON manifest to connect to native APIs.
Problem
Users integrating AI agents with tools via MCP face high latency due to 'wrapper tax' and complex integration processes requiring heavy middleware.
Solution
An open protocol (UTCP) enabling direct tool calling via JSON manifest, bypassing middleware for lower latency. Example: Declare APIs in JSON to connect AI agents natively.
Customers
AI engineers and developers building agentic workflows needing lightweight, performant tool integration (e.g., AI startups, enterprise AI teams).
Unique Features
Eliminates wrapper tax via direct API calls; open standard with minimal JSON configuration vs. proprietary protocols.
