uxc

UXC is a command-line tool that gives agents and automation one consistent way to discover and invoke remote capabilities across OpenAPI, MCP, GraphQL, gRPC and JSON-RPC. The workflow is discovery-first: list what a host exposes with -h, inspect a specific operation, then call it with key=value arguments, nested paths, per-field JSON or a full JSON payload. Output is deterministic JSON by default, with an opt-in text mode.

Auth is handled separately from commands, with credentials that store bearer tokens, API keys, multi-field or signed credentials and OAuth for supported MCP HTTP flows, and bindings that match endpoints to credentials. A daemon provides session reuse and background subscriptions over WebSocket or polling, and the repository ships official skills for tools such as Playwright MCP, Chrome DevTools MCP, Context7, DeepWiki, Notion, Slack and Discord. The README is explicit about what UXC is not: a hosted platform, an API gateway or a workflow orchestrator. It installs with Homebrew, an install script or cargo, and native Windows is no longer supported, so Windows users go through WSL.
