# UXC — One CLI for OpenAPI/MCP/GraphQL Tools

> One CLI to discover and invoke tools across OpenAPI, MCP, GraphQL, gRPC, and JSON-RPC with one contract; verified 108★, pushed 2026-05-14.

## Install

Copy the content below into your project:

## Quick Use

```bash
brew tap holon-run/homebrew-tap && brew install uxc
uxc petstore3.swagger.io/api/v3 -h
uxc petstore3.swagger.io/api/v3 get:/pet/{petId} petId=1
```

## Intro

One CLI to discover and invoke tools across OpenAPI, MCP, GraphQL, gRPC, and JSON-RPC with one contract; verified 108★, pushed 2026-05-14.

**Best for:** Teams standardizing how agents call remote APIs across mixed protocol stacks

**Works with:** Rust-based CLI; works against schema-described hosts across OpenAPI/MCP/GraphQL/gRPC/JSON-RPC (per README examples)

**Setup time:** 8-18 minutes

### Key facts (verified)

- GitHub: 108 stars · 7 forks · pushed 2026-05-14.
- License: MIT · owner avatar + repo URL verified via GitHub API.
- README-backed entrypoint: `brew tap holon-run/homebrew-tap && brew install uxc`.

## Main

- Use help-first discovery (`<host> -h`, `<host> <op> -h`) so agents don’t guess payload shape before calling.

- Standardize invocation across protocols: keep your automation using one CLI contract even when services vary (OpenAPI/GraphQL/MCP).

- Prefer deterministic JSON output in pipelines so downstream agents/tools can parse and diff results reliably.

- Start with a low-risk host (e.g., petstore) to learn argument styles (`key=value`, nested paths, per-field JSON).

### Source-backed notes

- README documents a consistent invocation pattern: `uxc <host> -h`, then `uxc <host> <operation_id> ...`.
- README shows installs via Homebrew, install script, Cargo, and from-source builds.
- README includes examples for OpenAPI, GraphQL, MCP, and JSON-RPC under one CLI contract.

### FAQ

- **Is it MCP-only?**: No — README explicitly targets OpenAPI/GraphQL/gRPC/JSON-RPC and unifies MCP with adjacent protocols.
- **How do I install quickly?**: Use Homebrew (`brew install uxc`) or the `scripts/install.sh` method from README.
- **What’s a safe first task?**: Run `uxc <host> -h` and invoke a read-only operation on a public demo endpoint before adding auth.

## Quick Use

```bash
brew tap holon-run/homebrew-tap && brew install uxc
uxc petstore3.swagger.io/api/v3 -h
uxc petstore3.swagger.io/api/v3 get:/pet/{petId} petId=1
```

## Intro

UXC 用一个 CLI 统一调用 OpenAPI/MCP/GraphQL/gRPC/JSON-RPC：发现→检查→结构化调用，并输出确定性 JSON；已验证 108★，更新于 2026-05-14。

**Best for:** 需要在多协议栈里统一 agent 调用方式的团队（避免每个服务一个脚本）

**Works with:** Rust CLI；按 README 示例可对接 OpenAPI/MCP/GraphQL/gRPC/JSON-RPC 等 schema 描述的 host

**Setup time:** 8-18 minutes

### Key facts (verified)

- GitHub：108 stars · 7 forks；最近更新 2026-05-14。
- 许可证：MIT；作者头像与仓库链接均已通过 GitHub API 复核。
- README 中可对照的入口命令：`brew tap holon-run/homebrew-tap && brew install uxc`。

## Main

- 用 help-first 发现流程（`<host> -h` / `<host> <op> -h`）让 agent 先看清参数结构再调用，减少“猜 JSON”。

- 把多协议统一到一个调用契约：OpenAPI/GraphQL/MCP 混用时也能保持同一套 CLI 调用方式。

- 在自动化链路里坚持确定性 JSON 输出，方便下游解析、比对与审计。

- 先从低风险示例 host（如 petstore）练习参数写法（`key=value`、嵌套路径、字段级 JSON）。

### Source-backed notes

- README 说明统一调用模式：`uxc <host> -h`，再 `uxc <host> <operation_id> ...`。
- README 提供 Homebrew、安装脚本、Cargo 与源码安装方式。
- README 在同一 CLI 契约下给出 OpenAPI/GraphQL/MCP/JSON-RPC 示例。

### FAQ

- **它只支持 MCP 吗？**：不是；README 明确覆盖 OpenAPI/GraphQL/gRPC/JSON-RPC，并把 MCP 纳入统一调用模型。
- **怎么最快安装？**：用 Homebrew（`brew install uxc`）或按 README 的 `scripts/install.sh` 安装。
- **安全的第一步做什么？**：先 `uxc <host> -h` 查看接口，再在公开 demo endpoint 上跑只读操作，确认调用格式后再接鉴权。
