简道云 MCP 服务

基于 FastMCP 3.x,通过 SSE 协议将简道云表单操作封装为 9 个 MCP Tools,供 Claude Code 或其他 MCP 客户端调用。

特性

  • API Key 一次配置,处处生效 — 在客户端连接时通过 Authorization header 传入,后续调用自动携带,无需每次传参
  • 9 个 Tools — 覆盖应用发现 → 表单探索 → 数据读写全流程
  • Docker 一键部署 — 开箱即用,易于自托管
  • HTTPS 支持 — 提供 Nginx 反向代理配置示例

快速开始

前置条件

  • Docker(推荐)或 Python 3.12+
  • 简道云账号及 API Key(在简道云后台「设置」→「API 管理」获取)

1. 克隆仓库

git clone https://github.com/your-username/jiandaoyun-mcp.git
cd jiandaoyun-mcp

2. 启动服务

方式一:Docker(推荐)

docker compose up -d --build

服务默认绑定在 127.0.0.1:8765,仅本机可访问。

方式二:直接运行(Python 3.12+)

pip install -r requirements.txt
python server.py

3. 验证服务

curl -i http://localhost:8765/sse
# 期望响应:HTTP/1.1 200 OK,Content-Type: text/event-stream

4. 配置 MCP 客户端

Claude Code CLI:

claude mcp add --transport sse jiandaoyun http://localhost:8765/sse \
  --header "Authorization: Bearer <your_api_key>"

手动编辑 ~/.claude.json

{
  "mcpServers": {
    "jiandaoyun": {
      "type": "sse",
      "url": "http://localhost:8765/sse",
      "headers": {
        "Authorization": "Bearer <your_api_key>"
      }
    }
  }
}

配置完成后重启 Claude Code 即可使用。


远程部署(公网 / 局域网)

如需将服务部署在远程服务器供多端共用,推荐用 Nginx

开放端口绑定(跳过 Nginx 时)

docker-compose.yml 中的端口绑定改为监听所有网卡:

ports:
  - "0.0.0.0:8765:8765"

然后客户端使用 http://<server-ip>:8765/sse 连接(明文,仅内网推荐)。

配置 Nginx HTTPS(推荐用于公网)

  1. nginx/jiandaoyun-mcp.conf 复制到 /etc/nginx/conf.d/

  2. 按注释修改以下三项:

    占位符 说明
    your.domain.com 你的域名
    /path/to/your/cert.crt SSL 证书路径
    /path/to/your/cert.key SSL 私钥路径
  3. 重载 Nginx:

    nginx -t && nginx -s reload
    
  4. 客户端连接地址改为:

    claude mcp add --transport sse jiandaoyun https://your.domain.com:9444/sse \
      --header "Authorization: Bearer <your_api_key>"
    

SSE 关键配置说明(已写入模板,勿删):

配置项 说明
proxy_buffering off 禁用响应缓冲,保证事件实时推送
proxy_cache off 禁用缓存
proxy_read_timeout 86400 超时设为 24h,维持长连接
proxy_set_header Connection "" 关闭 keep-alive 改写

测试用自签名证书

openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
  -keyout cert.key -out cert.crt \
  -subj "/CN=localhost"

API Key 传递方式

服务端支持以下三种方式(优先级从高到低):

优先级 方式
1 Authorization: Bearer <key> header(推荐)
2 X-Api-Key: <key> header
3 ?api_key=<key> query 参数(仅 SSE 握手请求有效)

可用 Tools(共 9 个)

推荐使用流程

list_apps → list_forms → get_form_fields → 读写操作

先了解有哪些应用和表单,再获取字段结构(字段 namelabeltype),最后进行数据操作。


应用 / 表单发现

list_apps — 列出所有应用

limit:  100    # 可选,每页返回数量,默认 100
skip:   0      # 可选,跳过条数,用于分页

返回:apps[],每项包含 app_idname


list_forms — 列出应用下所有表单

app_id: "5e3b1234abcd5678ef901234"

返回:forms[],每项包含 entry_idname


get_form_fields — 获取表单字段结构

app_id:   "5e3b1234abcd5678ef901234"
entry_id: "5e3b5678abcd1234ef901234"

返回:widgets[],每项包含 name(字段 ID,如 _widget_1234)、label(显示名)、type

常见字段类型: text(单行文本)、textarea(多行文本)、number(数字)、datetime(日期时间)、combo(下拉框)、radio(单选)、checkbox(多选)


数据读取

get_record — 查询单条记录

app_id:   "5e3b..."
entry_id: "5e3b..."
data_id:  "66a1234567890abc12345678"    # 记录的 _id 字段

query_records — 查询多条记录

基础用法:

app_id:   "5e3b..."
entry_id: "5e3b..."
limit:    100
fields:   ["_widget_xxx", "_widget_yyy"]    # 可选,指定返回字段

简单筛选(filters)— 精确匹配:

filters: {"_widget_xxx": "张三", "_widget_yyy": "已完成"}

复杂筛选(filter)— 支持 gt/lt/like/range 等:

filter: {
  "rel": "and",
  "cond": [
    {"field": "_widget_xxx", "type": "gt",   "value": ["100"]},
    {"field": "_widget_yyy", "type": "like", "value": ["张"]}
  ]
}

filterfilters 同时传入时,filter 优先生效。

翻页(游标分页):

# 第一页
query_records(app_id=..., entry_id=..., limit=100)

# 取最后一条记录的 _id,作为下一页的 data_id
query_records(app_id=..., entry_id=..., limit=100, data_id="上一页最后一条的_id")

数据写入

data 字段格式

data = {
    "_widget_1234567890ab": {"value": "文本内容"},    # 文本字段
    "_widget_abcdef123456": {"value": 123},            # 数字字段
    "_widget_fedcba654321": {"value": "2024-06-01"},   # 日期字段
}

字段的 name(如 _widget_1234)通过 get_form_fields 获取。


create_record — 新建单条记录

app_id:       "5e3b..."
entry_id:     "5e3b..."
data:         {...}
data_creator: "username"    # 可选,指定创建者用户名

返回:{"data": {"_id": "新记录ID", ...}}


create_records_batch — 批量新建(≤ 100 条)

app_id:    "5e3b..."
entry_id:  "5e3b..."
data_list: [
  {"_widget_xxx": {"value": "第一条"}},
  {"_widget_xxx": {"value": "第二条"}}
]

返回:{"status": "success", "success_count": 2, "success_ids": ["id1", "id2"]}


update_record — 修改单条记录

只需传入需要修改的字段,未传字段保持原值。

app_id:   "5e3b..."
entry_id: "5e3b..."
data_id:  "66a1234567890abc12345678"
data:     {"_widget_xxx": {"value": "修改后的值"}}

delete_record — 删除单条记录

⚠️ 删除不可恢复,请谨慎操作。

app_id:   "5e3b..."
entry_id: "5e3b..."
data_id:  "66a1234567890abc12345678"

返回:{"status": "success"}


修改默认端口

服务默认使用 8765。如需修改:

  1. docker-compose.yml — 修改 ports 中的宿主机端口映射
  2. server.py 末尾 — 修改 mcp.run(port=8765) 中的值

运维命令

# 查看服务状态
docker compose ps

# 实时查看日志
docker compose logs -f

# 重启服务
docker compose restart

# 更新代码后重新部署
docker compose up -d --build

# 停止并移除容器
docker compose down
