How to Set Up and Use DX Toolkit

The DX Toolkit MCP server integrates You.com's AI-powered search and research capabilities into any MCP-compatible client, including Claude Desktop, Cursor, Windsurf, and VS Code. It exposes You.com's production search infrastructure — not a scraper — giving agents access to real-time web search, deep research synthesis, and web content retrieval. A free tier is available without signup, and authenticated tiers unlock research and finance tools.

Prerequisites

  • Node.js 18 or later installed for npx usage
  • An MCP-compatible client (Claude Desktop, Cursor, Windsurf, VS Code, etc.)
  • For free tier: no API key required — set YDC_PROFILE=free
  • For authenticated access: a You.com API key from you.com/platform/api-keys
1

Choose your access tier

The free tier (YDC_PROFILE=free) gives access to the you-search tool with no signup. Authenticated access via YDC_API_KEY unlocks you-research and you-contents. Finance tools (you-finance) require requesting access separately.

2

Add the MCP server to your client config

Edit your MCP client's configuration file to add the You.com DX Toolkit server. For Claude Desktop this is ~/Library/Application Support/Claude/claude_desktop_config.json on macOS.

{
  "mcpServers": {
    "you": {
      "command": "npx",
      "args": ["-y", "@youdotcom-oss/mcp"],
      "env": {
        "YDC_PROFILE": "free"
      }
    }
  }
}
3

Or install via Claude Code CLI

If you use Claude Code, you can add the server in one command using the MCP add subcommand.

claude mcp add you -e YDC_PROFILE=free -- npx @youdotcom-oss/mcp
4

Switch to authenticated access (optional)

Obtain a You.com API key from the developer dashboard, then update the env block in your config to use YDC_API_KEY instead of YDC_PROFILE. This unlocks you-research (multi-source synthesis) and you-contents (full page retrieval).

{
  "mcpServers": {
    "you": {
      "command": "npx",
      "args": ["-y", "@youdotcom-oss/mcp"],
      "env": {
        "YDC_API_KEY": "your-api-key-here"
      }
    }
  }
}
5

Restart your MCP client

Restart Claude Desktop or reload your editor to pick up the new MCP server configuration. The you-search tool (and others depending on your tier) will now be available.

DX Toolkit Examples

Client configuration

Free-tier Claude Desktop configuration — no API key required.

{
  "mcpServers": {
    "you": {
      "command": "npx",
      "args": ["-y", "@youdotcom-oss/mcp"],
      "env": {
        "YDC_PROFILE": "free"
      }
    }
  }
}

Prompts to try

Example prompts that exercise the You.com search and research tools.

- "Search the web for the latest news about the EU AI Act and summarize the key points"
- "Research the top 5 open-source LLM frameworks in 2025 and compare their features"
- "Fetch the contents of https://example.com/article and extract the main arguments"
- "Find recent developer documentation for the Anthropic Claude API"
- "Search for benchmark comparisons between GPT-4o and Claude 3.5 Sonnet"

Troubleshooting DX Toolkit

Server starts but you-search returns no results

Confirm YDC_PROFILE is set to 'free' or a valid YDC_API_KEY is provided. If both are missing, the server may start but requests will be rejected with an authentication error.

you-research or you-contents tools are not available

These tools require an authenticated API key. Set YDC_API_KEY in the env block of your MCP config with a key obtained from you.com/platform/api-keys.

npx fails to download the package

Run 'npm cache clean --force' and retry. Alternatively pin a specific version: npx -y @youdotcom-oss/mcp@latest.
