Features

• ✅ MCP server framework with stdio transport
• ✅ Get笔记 API client with Bearer token authentication
• ✅ Rate limiting (2 QPS, 5000 requests/day)
• ✅ Comprehensive error handling and logging
• ✅ TypeScript with full type safety
• ✅ Three MCP tools:

Installation

Option 1: Install globally (recommended for frequent use)

npm install -g mcp-get-biji-server

Option 2: Use with npx (no installation required)

npx mcp-get-biji-server

Option 3: Install as project dependency

npm install mcp-get-biji-server

Configuration

1. Copy the environment template:

cp .env.example .env

2. Edit .env and add your API key:

GET_BIJI_API_KEY=your_api_key_here
GET_BIJI_API_BASE_URL=https://open-api.biji.com/getnote/openapi
LOG_LEVEL=info
REQUEST_TIMEOUT=30000
RATE_LIMIT_QPS=2
RATE_LIMIT_DAILY=5000

Usage with Claude Desktop

Edit your Claude Desktop config file (~/Library/Application Support/Claude/claude_desktop_config.json):

Using global installation:

{
  "mcpServers": {
    "get-biji": {
      "command": "mcp-get-biji-server",
      "env": {
        "GET_BIJI_API_KEY": "your_api_key_here",
        "GET_BIJI_DEFAULT_TOPIC_ID": "your_default_topic_id"
      }
    }
  }
}

Using npx:

{
  "mcpServers": {
    "get-biji": {
      "command": "npx",
      "args": ["-y", "mcp-get-biji-server"],
      "env": {
        "GET_BIJI_API_KEY": "your_api_key_here",
        "GET_BIJI_DEFAULT_TOPIC_ID": "your_default_topic_id"
      }
    }
  }
}

Using local installation:

{
  "mcpServers": {
    "get-biji": {
      "command": "node",
      "args": ["/path/to/node_modules/mcp-get-biji-server/build/index.js"],
      "env": {
        "GET_BIJI_API_KEY": "your_api_key_here",
        "GET_BIJI_DEFAULT_TOPIC_ID": "your_default_topic_id"
      }
    }
  }
}

Restart Claude Desktop to activate the server.

MCP Tools

1. knowledge_search

AI-enhanced search with deep processing.

Parameters:

• question (required): Search query
• topic_ids (required): Knowledge base ID list (currently supports 1)
• deep_seek (required): Enable deep thinking
• refs (optional): Include references
• history (optional): Conversation history for follow-up

2. knowledge_recall

Fast retrieval of raw content without AI processing.

Parameters:

• question (required): Search query
• topic_id (optional): Single knowledge base ID (preferred)
• topic_ids (optional): Knowledge base ID list
• top_k (optional): Number of top results (default: 10)
• intent_rewrite (optional): Enable intent rewriting
• select_matrix (optional): Enable result re-selection
• history (optional): Conversation history

Note: Either topic_id or topic_ids must be provided. topic_id takes priority.

3. get_rate_limit_stats

Get current API rate limit usage statistics.

Development

npm run build        # Compile TypeScript
npm run watch        # Watch mode compilation
npm run dev          # Build and run
npm test             # Run tests
npm start            # Run (must build first)

API Rate Limits

• QPS: 2 requests/second
• Daily: 5000 requests/day

The server automatically handles rate limiting with intelligent queuing.

项目概述

一个用于集成Get笔记API的Model Context Protocol (MCP)服务器,实现AI增强的知识库搜索和召回功能。

功能特性

• ✅ 基于stdio传输的MCP服务器框架
• ✅ 支持Bearer Token认证的Get笔记API客户端
• ✅ 速率限制 (2 QPS, 5000次/天)
• ✅ 完善的错误处理和日志记录
• ✅ TypeScript完整类型安全
• ✅ 三个MCP工具:
  • knowledge_search: AI增强知识库搜索
  • knowledge_recall: 原始内容召回
  • get_rate_limit_stats: 速率限制统计

安装

方式1: 全局安装 (推荐常用场景)

npm install -g mcp-get-biji-server

方式2: 使用 npx (无需安装)

npx mcp-get-biji-server

方式3: 作为项目依赖安装

npm install mcp-get-biji-server

配置

1. 复制环境变量模板:

cp .env.example .env

2. 编辑 .env 文件,添加您的API密钥:

GET_BIJI_API_KEY=your_api_key_here
GET_BIJI_API_BASE_URL=https://open-api.biji.com/getnote/openapi
LOG_LEVEL=info
REQUEST_TIMEOUT=30000
RATE_LIMIT_QPS=2
RATE_LIMIT_DAILY=5000

在Claude Desktop中使用

编辑Claude Desktop配置文件 (~/Library/Application Support/Claude/claude_desktop_config.json):

使用全局安装:

{
  "mcpServers": {
    "get-biji": {
      "command": "mcp-get-biji-server",
      "env": {
        "GET_BIJI_API_KEY": "your_api_key_here",
        "GET_BIJI_DEFAULT_TOPIC_ID": "your_default_topic_id"
      }
    }
  }
}

使用 npx:

{
  "mcpServers": {
    "get-biji": {
      "command": "npx",
      "args": ["-y", "mcp-get-biji-server"],
      "env": {
        "GET_BIJI_API_KEY": "your_api_key_here",
        "GET_BIJI_DEFAULT_TOPIC_ID": "your_default_topic_id"
      }
    }
  }
}

使用本地安装:

{
  "mcpServers": {
    "get-biji": {
      "command": "node",
      "args": ["/path/to/node_modules/mcp-get-biji-server/build/index.js"],
      "env": {
        "GET_BIJI_API_KEY": "your_api_key_here",
        "GET_BIJI_DEFAULT_TOPIC_ID": "your_default_topic_id"
      }
    }
  }
}

重启Claude Desktop以激活服务器。

• refs (可选): 返回引用来源
• history (可选): 对话历史,用于追问

2. knowledge_recall

快速召回原始内容,不经过AI处理。

参数:

• question (必填): 搜索问题
• topic_id (可选): 单个知识库ID(优先使用)
• topic_ids (可选): 知识库ID列表
• top_k (可选): 返回前N个结果(默认:10)
• intent_rewrite (可选): 启用意图重写
• select_matrix (可选): 启用结果重选
• history (可选): 对话历史

注意: topic_id 和 topic_ids 必须提供一个,优先使用 topic_id。

3. get_rate_limit_stats

获取当前API速率限制使用统计。

开发命令

npm run build        # 编译TypeScript代码
npm run watch        # 监听模式编译
npm run dev          # 编译并运行
npm test             # 运行测试
npm start            # 直接运行(需先编译)

API限制

• QPS限制: 2次/秒
• 日限制: 5000次/天

服务器内置智能排队的速率限制器,自动处理这些限制。
