How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

学习 Model Context Protocol (MCP)
教授专注的 Model Context Protocol (MCP) 路线。一次调用覆盖一节课。学习者应检查请求与响应、预测边界结果、运行或手工跟踪 lab,并在推进前记录课程 checkpoint。
使用宿主的调用语法
可移植 skill 名称是 learn-mcp。不要将某个宿主的语法说成协议规则。
| 宿主 | 开始或继续 |
| Codex | learn-mcp,或从 /skills 选择它 |
| Claude Code | /learn-mcp |
| 其他兼容宿主 | Use learn-mcp to start or resume the Model Context Protocol (MCP) path. |
选择课程前读取路线
唯一事实来源是 learning-paths/model-context-protocol.json。仓库可用时优先本地文件;否则从以下地址获取所需文件:
https://raw.githubusercontent.com/fancyboi999/ai-engineering-from-scratch-zh/main/<path>按 manifest 的 lessons 数组及其 order 进行。必修顺序为 06、07、08、09、10、11、12、13、14、15、16、18、17、28、29、30、31。第 16 课后,数字上的下一课不再是此路线的下一课。
对选中课程,完整读取 docs/zh.md 和 quiz.json。只在当前教学步骤需要时读取或运行 code/ 与 outputs/。采用课程声明的 protocol era。绝不把 legacy handshake 规则混进现代无状态 trace。
第 23 课是唯一可选 capstone。只能在所有必修行完成且 manifest prerequisitePaths 中第 19、20 课均完成后提供。绝不悄悄向此路径添加其他课程。
确立证据模式
第一次可执行 checkpoint 前,确定:
- 课程文件是否在本地可用。
python3 --version是否成功。- 学习者能否在当前工作目录写入
MCP-LEARNING.md。 - 学习者选择第 07 课的可选第二实现时,是否有 TypeScript runner。
本地文件和 Python 3 都可用时,采用 executable mode。记录绝对工作目录、精确命令、exit code、request id 与 method、选择的 protocol era,以及观察到的结果或错误。隐去 tokens、secrets、cookies、authorization headers 和敏感参数值。
仓库或 runtime 不可用时,采用 conceptual mode。阅读课程,手工跟踪一个小型 request 与 response,并将证据标为 Conceptual。将 runtime、transport、authorization 和 deployment 检查保留为 Pending。绝不把手工跟踪说成已执行通过。
可执行文件需要但缺失时,提供将仓库克隆到学习者选择目录的选项。克隆前等待确认。没有克隆时概念课仍必须可用。
查找或创建进度
在当前工作目录使用 MCP-LEARNING.md。不要将此路线写入 LEARNING.md,也不要修改 Agent Skills 进度。
决定不存在状态前,安全处理旧文件名:
- 若存在
MCP-LEARNING.md,使用它。若也有MCP-ENGINEERING-LEARNING.md,两个文件都不要覆盖;报告冲突并询问下一次更新由哪个文件拥有。 - 若
MCP-LEARNING.md不存在而MCP-ENGINEERING-LEARNING.md存在,在教学前将 legacy 文件在同目录改名为MCP-LEARNING.md(rename the legacy file toMCP-LEARNING.md)。字节级保留所有学习者笔记和证据行(Preserve every learner note and evidence row byte for byte)。不能原子 rename 时,先复制,验证新文件匹配,再删除 legacy 文件。 - 只有两个文件名均不存在时才创建新状态文件。绝不以空白模板替换 legacy 进度。
文件存在时保留所有学习者笔记和证据。从第一个标为 In progress 或 Next 的行继续。所有必修行都 Done 时,检查可选 capstone 前置条件,并报告确切缺失路径,不能重启路线。
文件不存在时,不经定位测验直接创建:

## Notes检查能够本地观察的事实。只询问无法安全推断的选择或授权。
在十分钟内开始第 06 课
首次调用时立即开始课程。从仓库根目录运行:
python3 phases/13-tools-and-protocols/06-mcp-fundamentals/code/main.py要求学习者识别重复的 protocol version 和 client capabilities、完整的 server/discover result、错误 -32022,以及没有 protocol-session creation 或 teardown。在拓展第 06 课其余内容前记录这些观察。
命令不能运行时,从课程展示一个现代 request 和 response,要求学习者标出每个 envelope field,并把结果记录为 conceptual evidence。命令 checkpoint 保持 pending。
强制执行公开部署闸门
任何 non-loopback bind、共享 ingress、hosted endpoint、registry publication 或其他公开部署前,从 manifest 读取 publicDeploymentGate。要求第 15 课 executable checkpoint,审阅目标与请求的 authority,并在外部行动前获得学习者明确确认。
任何必需证据缺失时,教授或重跑第 15 课,并将部署行动保持 pending。skill 调用不授予 network、credential、publishing 或 deployment authority。
学习屏幕
宿主能运行 Node.js 20 或更高版本,且能在学习者机器打开浏览器时,每次会话提出一次使用可移植技能 lesson-screen,按宿主调用方式呈现。它展示课程图表和带真实数值的代码执行过程,也能在教学期间为本课制作图表。学习者拒绝或没有本地浏览器时,只提供一次 aieng-zh.cn 的相应课程页。每次回复前用它的 events 命令读取点击。点击只是提示,绝不计作测验答案、检查点证据或实验结果;进度仍由本路线的证据规则决定。
教一节课
- 将选中行标为
In progress。说明其 manifest path、duration、group、protocol era 与 evidence mode。 - 描述本课可预防的一种生产失败。请学习者先预测 status、JSON-RPC result 或 state transition,再解释。
- 绘制一个 request boundary:producer、transport、consumer 以及各方验证的精确 fields。保持 protocol state、durable application state、transport state、authorization state 和 UI state 相互区分。
- 将 Build It 和 Use It 分成小节推进。对于代码,解释一个 invariant,要求预测,然后运行或跟踪能证伪它的最小 case。
- 演练一个成功案例和至少一个相关失败案例。优先记录精确 wire evidence:request id、method、protocol era、适用时 headers、body、status 或 error code、result type 和 terminal state。隐去 secret 值。
- 要求课程 manifest
checkpointEvidence的每一项。runtime evidence 必须来自观察输出;conceptual evidence 必须点明未执行的命令及剩余不确定性。 - 逐题提问所有
postquiz 项;quiz 无 staged 项时提问所有项。学习者回答前不揭示correct、答案索引或解释。回复提示绝不放入真实答案字母或答案分布;使用Reply with one letter: <A|B|C|D>. - 仅在课程 checkpoint 与 quiz 都完成后标为
Done。追加一条简洁的 Wire evidence,向 Notes 添加得分,将下一行设为Next,并更新Current。
通过 unit tests 不能替代指定 protocol evidence。不要从 in-process function 推断 HTTP behavior、从 authentication 推断 authorization、从 timeout 推断 cancellation,或从一个 SDK 推断 conformance。
收尾
结束时给出 quiz 得分、已记录的精确 checkpoint evidence、任何 pending 的 runtime 或 security evidence 及下一节 manifest 课程。除非学习者要求离开,否则保持在此路线。
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
