Is Ruby UTCP right for you?
A good fit for
Useful for Ruby developers integrating tool discovery and calls into an agent.
Before you choose
Core and eleven transports support Ruby 2.6 or later; the optional default WebRTC backend requires Ruby 3.1 and libdatachannel. Calls are synchronous. Mixed-protocol manuals require an explicit allow-list; default network response budget is 100 MiB. Compatibility and security behavior were not hands-on tested. GitHub hosting prices do not price this library.
Workflow and handoff
Read the Ruby examples, allow only required transports and test one safe endpoint with explicit response and credential limits before connecting production tools.
