About

A remote MCP Server demo using FastMCP and Streamable HTTP, offering tools (add, now, fetch_url_title, long_task with progress), resources, prompts, and autocomplete for remote client connections.

README

基于官方 MCP Python SDKFastMCP, 使用 Streamable HTTP 传输实现的远程 MCP Server,可被任意 MCP 客户端(如 Cursor)远程连接。

目录结构

.
├── server.py            # 远程 MCP Server(工具 / 资源 / 提示 / 进度 / 补全)
├── client.py            # 基础测试客户端
├── client_advanced.py   # 进阶客户端(进度 + 日志 + 自动补全)
├── curl_test.sh         # 用 curl 测试的脚本
├── requirements.txt     # 依赖
└── README.md

环境要求

  • Python 3.10+(本项目使用 3.11)

安装

python3.11 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

启动 Server

venv/bin/python server.py

默认监听 http://0.0.0.0:8000/mcp。可用环境变量调整:

MCP_HOST=0.0.0.0 MCP_PORT=9000 venv/bin/python server.py

运行测试客户端

另开一个终端:

venv/bin/python client.py                       # 基础:工具 / 资源 / 提示
venv/bin/python client_advanced.py              # 进阶:进度 + 日志 + 自动补全
venv/bin/python client.py http://127.0.0.1:9000/mcp

也可以用 curl 脚本(依赖 curljq):

./curl_test.sh                                  # 默认 http://127.0.0.1:8000/mcp
./curl_test.sh http://127.0.0.1:9000/mcp

Server 能力

类型 名称 说明
工具 add(a, b) 求和
工具 now(tz_offset_hours=8) 返回当前时间(默认东八区)
工具 fetch_url_title(url) 抓取网页标题(异步示例)
工具 long_task(steps) 长任务,实时上报进度(progress)日志(logging)
资源 config://app 静态配置
资源 greeting://{name} 动态参数资源
提示 summarize(text) 生成总结提示
补全 greeting://{name}name 按前缀返回候选名字(completion

进度 + 日志(long_task)

long_task 通过 ctx: Context 在执行中实时推送进度和日志。客户端注册回调即可接收:

async def on_log(params):      # 接收 ctx.info/debug 的日志
    print(params.level, params.data)

async def on_progress(progress, total, message):  # 接收进度
    print(f"{progress}/{total} {message}")

async with ClientSession(read, write, logging_callback=on_log) as session:
    await session.call_tool("long_task", {"steps": 5}, progress_callback=on_progress)

stateless_http 注意:无状态模式下不能直接用 ctx.report_progress(), 因为它未携带 related_request_id,进度通知无法关联到当前请求的 SSE 流而被丢弃。 本 demo 在 _report_progress() 中改为直接调用 session.send_progress_notification(...) 并显式传入 related_request_id=ctx.request_id。日志 ctx.info/debug 不受影响(SDK 已自动携带)。

自动补全(completion)

@mcp.completion() 注册全局补全处理器,为资源模板/提示的参数提供候选:

comp = await session.complete(
    ResourceTemplateReference(type="ref/resource", uri="greeting://{name}"),
    argument={"name": "name", "value": "小"},
)
print(comp.completion.values)   # => ['小明', '小红']

在 Cursor 中连接

~/.cursor/mcp.json(或项目 .cursor/mcp.json)中添加:

{
  "mcpServers": {
    "demo-remote": {
      "url": "http://127.0.0.1:8000/mcp"
    }
  }
}

说明

  • stateless_http=True:每个请求独立、无会话状态,便于远程部署和水平扩展。
  • 生产部署可放在 Nginx/网关之后,并自行实现鉴权(如校验 Authorization 头)。
