Why us?

Open-source pedigree.
Thought leadership.

We built the Universal Tool Calling Protocol and the first library for Code Mode, and we speak on agent infrastructure from MIT to MLCon.

Built by the team behind UTCP and the first ever library for Code Mode (Code Execution for Tool Calling).

We're deeply technical; we build at the protocol layer of AI.

Our team created the Universal Tool Calling Protocol, an open alternative to Anthropic's Model Context Protocol, championed by engineers at AWS, Adobe, Royal Bank of Canada and MuleSoft. It is what lets every capability in Bevel be exposed as a plain HTTP endpoint, with no proxy server in the middle. Our CodeMode library is what lets agents chain those tools through code instead of one call at a time.

Library

CodeMode

Tool-chaining through code execution rather than one call at a time.

Thank you very much for building UTCP. It's incredibly helpful for multi-tenant agentic AI applications, where MCP isn't always the best fit. I was actually reverting MCP servers back to hardcoded tool descriptions for my agentic AI systems when I came across UTCP, and I think it's fantastic to finally have a universal standard for this. I fully support UTCP, as I see big value in it for building scalable, multi-tenant AI applications.

UTCP is a great addition to the agent-tooling space as an alternative to MCP. What I appreciate about UTCP is that it doesn't ask you to rebuild anything. You describe the tools you already have, and agents call them natively, with no proxy server in the middle, no extra hop to operate and secure. It turns “integrate AI with our APIs” from a project into a description.
