## About

# duckduckgo-search MCP Server

English | [中文](README_zh.md)

A Model Context Protocol server for DuckDuckGo Search

This is a TypeScript-based MCP server that provides DuckDuckGo search functionality. It demonstrates core MCP concepts through:

- Integration with DuckDuckGo Search
- Easy-to-use search tool interface
- Rate limiting and error handling support

  

## Features

### Search Tool

- `duckduckgo_search` - Perform web searches using DuckDuckGo API
  - Required parameter: `query` (search query, max 400 characters)
  - Optional parameter: `count` (number of results, 1-20, default 10)
  - Optional parameter: `safeSearch` (safety level: strict/moderate/off, default moderate)
  - Returns formatted Markdown search results

### Rate Limits

- Maximum 1 request per second
- Maximum 15000 requests per month

## Development

### Prerequisites

- Node.js >= 18
- pnpm >= 8.0.0

### Installation

```bash
# Install pnpm if not already installed
npm install -g pnpm

# Install project dependencies
pnpm install
```

### Build and Run

Build the server:

```bash
pnpm run build
```

For development with auto-rebuild:

```bash
pnpm run watch
```

## Setup in Claude Desktop

To use with Claude Desktop, add the server config:

On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
On Windows: `%APPDATA%/Claude/claude_desktop_config.json`

```json
# online
{
  "mcpServers": {
    "duckduckgo-search": {
        "command": "npx",
        "args": [
          "-y",
          "duckduckgo-mcp-server"
        ]
    }
  }
}

# local
{
  "mcpServers": {
    "duckduckgo-search": {
      "command": "node",
      "args": [
        "/path/to/duckduckgo-search/build/index.js"
      ]
    }
  }
}
```

### Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script:

```bash
pnpm run inspector
```

The Inspector will provide a URL to access debugging tools in your browser.
