项目价值

本项目提供两份核心资产:

| 资产 | 价值 | |------|------| | 兼容性测试 | 35 个测试工具 + 3 种传输模式,验证阶跃客户端 MCP 兼容性 | | 开发 Skill | 6 条致命规则 + 17 条约束 + 3 套模板,让 AI 帮你写 MCP 服务器 |

---

一、兼容性测试

测试覆盖

| 类别 | 数量 | 说明 | |------|------|------| | A - 核心能力 | 5 | 协议版本、能力声明、工具调用、全类型参数 | | B - 复杂参数 | 6 | 嵌套对象、大数据、长操作、并发、Unicode | | C - 高级能力 | 4 | 进度通知、取消、批量请求、自动补全 | | D - 边界条件 | 8 | 空参数、超长字符串、特殊字符、幂等性 | | E - 极端条件 | 1 | 超时边界 | | G - GUI Agent | 7 | 截图、鼠标、键盘、自动化演示 | | H - Elicitation | 2 | 表单式、URL 式 | | I - Sampling | 2 | 基础、带工具 |

传输模式

| 模式 | 目录 | 状态 | |------|------|------| | NPX (stdio) | stdio/npx/ | 35/35 通过 | | UVX (stdio) | stdio/uvx/ | 35/35 通过 | | HTTP/SSE | http/ | 35/35 通过 |

快速开始

HTTP 模式(推荐开发调试): ``bash cd http python full_test_server.py ``

阶跃客户端配置: ``json { "mcpServers": { "mcp-http-test": { "url": "http://127.0.0.1:3372/mcp" } } } ``

NPX 模式(推荐 stdio 测试): ``json { "mcpServers": { "mcp-npx-test": { "command": "npx", "args": ["-y", "<项目路径>/stdio/npx"] } } } ``

UVX 模式(不推荐开发时用): ``json { "mcpServers": { "mcp-uvx-test": { "command": "uvx", "args": ["--from", "<项目路径>/stdio/uvx", "mcp-uvx-test"] } } } ``

⚠️ UVX 模式有严重的缓存问题,每次修改源码都需要清理缓存 + 更新版本号。详见 docs/stdio/uvx/ISSUES.md

二、开发 Skill

什么是 Skill

Skill 是阶跃 AI 桌面助手的扩展能力包。加载后,AI 获得"编写阶跃兼容 MCP 服务器"的专业知识。

Skill 内容

| 内容 | 说明 | |------|------| | 致命规则 TOP 6 | 违反必崩(outputSchema、async main、命令格式...) | | 17 条约束 | 设计/编码/部署/排查全覆盖 | | 决策树 | Connection closed 5 种原因排查 | | 3 套模板 | NPX / UVX / HTTP 完整项目模板 |

使用方法

  1. 打包 skills/stepfun-mcp/ 文件夹为 zip
  2. 在阶跃客户端中添加技能(导入 zip)
  3. 告诉阶跃你想实现的功能
