# 这个 skill 适合什么用户?能做哪些任务?
## 概览
MCP Python SDK 是 Model Context Protocol 的参考实现(github.com/modelcontextprotocol/python-sdk)—— Anthropic 主导的开放标准,让 AI host(Claude / Cursor 等)通过 JSON-RPC 2.0 跟工具服务端对话。
两个 server 接口:低层 Server(构造器注入 handler)和高层 MCPServer(装饰器 API,原名 FastMCP)。三个传输共享结构化 (read_stream, write_stream) AnyIO 契约:stdio(行分隔 JSON)、传...

## 知识规模
- **50 条约束** (1 fatal + 49 non-fatal)
- 上游源码: `modelcontextprotocol/python-sdk` @ commit `3d7b311d`
- 蓝图 ID: `finance-bp-140`
## 用法
Host AI(Claude Code / Cursor / OpenClaw)读 `references/seed.yaml`,按其中的:
- `intent_router` 匹配用户意图
- `architecture` 理解项目架构
- `constraints` 应用 anti-pattern 约束
- `business_decisions` 参考核心设计决策
## FAQ 摘要
### 这个 skill 适合什么用户?能做哪些任务?
适合需要给 Claude / Cursor 等 AI host 提供工具服务的工程师:发布公司内部 API 给 AI 调用、暴露文件 / 数据库为 Resources、提供 prompt 模板等。本 skill 覆盖 stdio(本地)/ SSE(旧)/ streamable-http(推荐)三种 server 形态。访问 doramagic.ai/r/mcp-python-sdk 查看完整说明。
### 需要准备什么环境?依赖什么?
Python 3.10+,AnyIO(asyncio 或 trio 后端),Pydantic v2(type schema 生成),Starlette(HTTP/SSE/streamable-http 托管),OpenTelemetry(可选,分布式追踪)。Windows 客户端 stdio 需 pywin32 用于 Job Object 进程树终止;POSIX 用 os.killpg。
### 会踩哪些坑?这个 skill 怎么防护?
本 skill 内置 50 条约束(1 条 fatal)。典型踩坑:(1) commit 3d7b311 的 README 仍 import 改名前的 FastMCP(26 处 import 行 + 10 处文件路径失效),照抄 quickstart 必失败;
