What Hacker News says

Started on working on an alternative protocol, which lets agents call native endpoints directly (HTTP/CLI/WebSocket) via “manuals” and “providers,” instead of spinning up a bespoke wrapper server: https://github.com/universal-tool-calling-protocol/python-ut...
even connects to MCP servers
if you take a look, would love your thoughts
In MCP doesn't need tools, it needs codeUTCP: Open, direct alternative to MCP for tool calling
