Connects company intelligence and corporate contact directories directly to your assistant. Helps build prospect lists and prepare for sales calls.
claude mcp add --transport http zoominfo https://mcp.zoominfo.com/mcpWhat ZoomInfo does
This package links your agent to ZoomInfo hosted intelligence through https://mcp.zoominfo.com/mcp. It supplies your development workflow with firmographic details and intent signals. The assistant can look up corporate structures and leadership changes directly from chat.
Built-in task playbooks guide the agent to format findings into concise briefs and outreach drafts rather than raw JSON payloads. Connections run over HTTP and complete user authorization through OAuth.
Without an active ZoomInfo corporate account that includes API access, the connection will fail. No secret tokens reside in repository files because authorization happens through the provider login flow.
What it helps with
- Identify decision-makers and buying committee members at target accounts
- Enrich company profiles with technology adoption signals and business metrics
- Generate filtered account lists matching custom prospecting criteria
- Prepare background dossiers ahead of sales conversations
