博客园 MCP 服务

MCP Server Python License

通过 MCP(Model Context Protocol) 协议,将博客园 Open API 封装为 AI 可调用的工具。让你在 任何 MCP 客户端(QwenPaw、Claude Desktop、Cline 等)中直接用自然语言发布博客园文章。


功能

  • create_post — 发布 Markdown 博文到博客园
  • ✅ Token 通过 .env 管理,不含硬编码
  • ✅ 支持任何 MCP 客户端接入

目录


快速开始

1. 克隆 / 下载项目

git clone https://github.com/你的用户名/cnblogs-mcp.git
cd cnblogs-mcp

2. 创建虚拟环境

python -m venv .venv
source .venv/bin/activate      # macOS / Linux
# .venv\Scripts\activate       # Windows

3. 安装依赖

pip install -r requirements.txt

4. 配置 Token

cp .env.example .env

编辑 .env,填入你的博客园 Personal Access Token:

CNBLOGS_TOKEN=your_token_here

5. 运行测试

# 验证 MCP 服务能正常启动
printf '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}\n{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}\n' \
  | python cnblogs_mcp.py 2>/dev/null | grep '"name"'

正常输出:

{"jsonrpc":"2.0","id":2,"result":{"tools":[{"name":"create_post",...}]}}

获取 Token

  1. 登录 博客园
  2. 进入 个人设置 → 安全设置 → Personal Access Token
  3. 点击「创建 Token」,填写名称和权限(需要「发表随笔」权限)
  4. 复制生成的 Token,填入 .env 文件

⚠️ Token 仅显示一次,请妥善保存。


客户端接入

1. QwenPaw

在 QwenPaw 工作目录下找到 agent.json,添加 MCP 客户端:

{
  "mcp": {
    "clients": {
      "cnblogs": {
        "name": "cnblogs",
        "description": "博客园博文发布",
        "enabled": true,
        "transport": "stdio",
        "command": "/absolute/path/to/cnblogs-mcp/.venv/bin/python",
        "args": ["/absolute/path/to/cnblogs-mcp/cnblogs_mcp.py"],
        "env": {
          "DOTENV_PATH": "/absolute/path/to/cnblogs-mcp/.env"
        }
      }
    }
  }
}

重启 QwenPaw:

qwenpaw daemon restart

2. Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json 中添加:

{
  "mcpServers": {
    "cnblogs": {
      "command": "/absolute/path/to/cnblogs-mcp/.venv/bin/python",
      "args": ["/absolute/path/to/cnblogs-mcp/cnblogs_mcp.py"],
      "env": {
        "DOTENV_PATH": "/absolute/path/to/cnblogs-mcp/.env"
      }
    }
  }
}

重启 Claude Desktop。

3. Cline / Roo Code

在 VS Code 设置中搜索「MCP」,找到 MCP Servers,添加:

{
  "cnblogs": {
    "command": "/absolute/path/to/cnblogs-mcp/.venv/bin/python",
    "args": ["/absolute/path/to/cnblogs-mcp/cnblogs_mcp.py"],
    "env": {
      "DOTENV_PATH": "/absolute/path/to/cnblogs-mcp/.env"
    }
  }
}

4. 其他 MCP 客户端

通用配置模板:

参数
command .venv/bin/python(项目内虚拟环境的 Python)
args ["./cnblogs_mcp.py"]
env.DOTENV_PATH .env 文件的绝对路径

💡 如果 MCP 客户端不支持 DOTENV_PATH,也可以直接用 env.CNBLOGS_TOKEN 传入 token。


手动测试

cd cnblogs-mcp

# 测试 1:初始化 + 工具列表
printf '...' | python cnblogs_mcp.py

# 测试 2:发布一篇博文
printf '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}\n{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"create_post","arguments":{"title":"测试","body":"## 你好\n\n这是一篇测试文章。"}}}\n' | python cnblogs_mcp.py 2>/dev/null

正常返回:

{"success": true, "postId": 12345678, "postUrl": "https://www.cnblogs.com/你的博客名/p/12345678"}

错误处理

错误信息 原因 解决方案
未配置 CNBLOGS_TOKEN .env 未配置或路径错误 检查 .env 文件是否存在且 DOTENV_PATH 正确
API 错误: 401 Token 无效或已过期 重新在博客园创建 Token
API 错误: 403 Token 权限不足 创建 Token 时确保勾选「发表随笔」
API 错误: 400 请求格式有误 检查 title 和 body 是否为空
请求超时 网络问题 检查网络后重试
MCP 连接后工具列表为空 show_banner 问题 确保使用 mcp.run(show_banner=False)

API 参考

工具:create_post

参数:

参数 类型 必填 说明
