Setup

Claude Desktop

Edit your config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "derrick": {
      "command": "npx",
      "args": ["derrick-mcp"]
    }
  }
}

Claude Code

Add to .mcp.json at your project root (or ~/.claude/settings.json for global):

{
  "mcpServers": {
    "derrick": {
      "command": "npx",
      "args": ["derrick-mcp"]
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "derrick": {
      "command": "npx",
      "args": ["derrick-mcp"]
    }
  }
}

Other MCP clients

Any client that supports the MCP protocol over stdio can use this server. The command is npx derrick-mcp.

First use

Once connected, tell the AI:

"Configure Derrick with my API key: YOUR_KEY"

The key is saved to ~/.derrick-mcp/.env and persists across sessions.

Available tools

Two built-in tools are always available:

Tool	Description
`derrick_configure`	Save your API key
`derrick_account`	Check your credits and account info

All other tools (find email, enrich profile, search company, etc.) are loaded dynamically from the API. Ask the AI "What can Derrick do?" to see the full list.

Environment variable

Instead of using derrick_configure, you can set the API key as an environment variable:

{
  "mcpServers": {
    "derrick": {
      "command": "npx",
      "args": ["derrick-mcp"],
      "env": {
        "DERRICK_API_KEY": "your-key-here"
      }
    }
  }
}

Development

cd MCP
npm install
npm run build     # compile TypeScript
npm run dev       # run with tsx (hot reload)
npm start         # run compiled version

A3.5/5.0

Scored 2026-06-21 01:45 across 22 tools

Disambiguation4/5

Most tools have clearly distinct purposes, but a few overlap (e.g., find_email vs website_contact_social both extract emails, though from different sources; enrich_profile vs follower count both enrich profiles). Descriptions are detailed enough to usually disambiguate.

Naming Consistency5/5

All tools follow the 'derrick_' prefix with snake_case and a consistent verb_noun or verb_preposition_noun pattern (e.g., search_companies, find_email, configure, help). No mixing of conventions.

Tool Count4/5

22 tools is slightly above the ideal range but justified by the breadth of functionality (account, enrichment, search, verification, push, help, upgrade). No redundant tools, each adds value.

Completeness4/5

The tool set covers a wide range of sales intelligence needs: company and profile enrichment, email/phone finding, website extraction, SERP search, verification, and account management. Minor gaps like absence of a bulk operation tool or a direct delete tool are acceptable given the domain.
