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.

Hey Product Hunt

As we were tinkering with Universal Tool Calling Protocol (UTCP) we kept hearing about the same hurdle: Cool spec but where s the list of tools I can actually call?

Hi community,
Thanks a lot for sharing your support for the UTCP launch. Since our goal behind the UTCP (in addition to the technical elegance) is that no single organization should have any control over the protocol that governs agent tool calling, therefore the main contributors behind UTCP don't belong to a single company or country, for that matter.
To make it even more grassroots and community-driven, we've also launched a RFC (Request for Comments). Please check it out, and let's collectively build a kickass protocol for agent tool calling:

Also, if you'd like to contribute, please reach out. Or just drop a on the GitHub to keep the flywheel going.

MCP has paved the way for the ease of use of LLMs with our day-to-day tools. UTCP takes it further with better specification and security from the get-go. I would love to see UTCP standard being implemented alongside MCP.

Much simpler to use than MCP

I never understood why MCP needs to rely so heavily on heavy client/server architecture. This direct way of having LLMs call endpoints makes it much more easy and efficient to implement tool calling :)
