Obv biased since I'm part of the team building it, but we think its super elegant. It uses a simple JSON manifest to connect to native APIs, so no need to build wrappers. Would love if you give it a try, and share your experience.
We're also implementing a UTCP-MCP bridge, as the last MCP server you'll ever need. (https://github.com/universal-tool-calling-protocol/utcp-mcp)
