Protocols

UXC presents multiple protocol families through one top-level CLI contract.

Supported Protocols

• OpenAPI / Swagger
• MCP over HTTP and stdio
• GraphQL introspection and execution
• gRPC reflection-based discovery and unary invocation
• JSON-RPC with OpenRPC-style discovery

Operation Naming

• OpenAPI: method:/path
• gRPC: Service/Method
• GraphQL: query/name or mutation/name
• MCP: tool name
• JSON-RPC: method name

Runtime Extensions

Related runtime support also includes:

• daemon-backed subscription lifecycle
• WebSocket-based subscription flows
• polling-based subscriptions
• provider-aware event intake for systems such as Slack, Discord, and Feishu

Notes

UXC does not try to erase protocol differences completely. It tries to make discovery, inspection, auth attachment, invocation, and output feel consistent across them.
