Derrick App
Derrick MCP Server
B2B data enrichment tools for any MCP-compatible AI client — find emails, enrich LinkedIn profiles, search companies, and more.
Tools are dynamically loaded from the Derrick API at startup, so new actions are available automatically.
Prerequisites
- A Derrick account with the Standard plan ($20/mo) or above
- An API key (get it from: Google Sheets > Derrick menu > burger icon > API)
- Node.js 22+
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
