cd opafex-mcps
npm install
npm run build
# Run the enrichment server (mock mode — no API keys needed)
node packages/enrichment/dist/index.js
Create or edit .mcp.json in your project root:
{
"mcpServers": {
"enrichment": {
"command": "node",
"args": ["/path/to/opafex-mcps/packages/enrichment/dist/index.js"],
"env": {
"CLEARBIT_API_KEY": "sk-...",
"HUNTER_API_KEY": "...",
"TWILIO_ACCOUNT_SID": "...",

}
}
}
}
All servers work in mock mode when API keys are omitted — great for development and testing.
