FullEnrich — Claude Code MCP server: what it does, how to install
Connects verified B2B prospecting to AI agents. It discovers business email addresses and direct phone numbers using multi-vendor waterfall lookups.
claude mcp add --transport http fullenrich https://mcp.fullenrich.com/mcpWhat FullEnrich does
This remote server queries contact records sequentially across more than 25 data vendors until it confirms a valid email or phone number. It exports results into CSV or JSON files. The endpoint cannot write to your CRM directly. If you want records synced, you must configure an external CRM connector, which asks for confirmation before making changes.
Setup requires an active FullEnrich workspace with credits. The server authenticates through OAuth 2.1 without manual API keys. Contact previews are free, while enrichment spends credits only when data is verified: roughly 1 credit per email and 10 per phone number. If an enriched record turns out invalid, the platform refunds the spent balance.
