ZoomInfo MCP Server

ZoomInfo MCP is an official, provider-hosted MCP server that connects ZoomInfo's B2B intelligence graph (100M+ company profiles and 300M+ professional contacts) to MCP-compatible AI clients like Claude Desktop, Claude Code, Cursor, and Windsurf. Instead of writing API integration code, agents can call ZoomInfo as a native tool to search companies and contacts, enrich records with firmographics and technographics, pull intent signals and Scoops, and run deeper account or contact research.

The server is grouped into three families of tools: Finding tools (Search Companies, Search Contacts, Find Similar Companies/Contacts, Find Recommended Contacts, Search Intent, Search Scoops), Enriching tools (Enrich Companies, Enrich Contacts, Enrich Intent, Enrich Scoops, Enrich News), and Researching tools (Account Research, Contact Research). Authentication is OAuth 2.0 with ZoomInfo SSO, so per-user role-based access control from the ZoomInfo platform carries through to the MCP session.

Because it is provider-hosted at https://mcp.zoominfo.com/mcp, there is no self-hosted server to install. Usage draws from your existing ZoomInfo entitlement: Data Credits are consumed per new company/contact record (with 12-month update refresh) and AI Credits are consumed by the research-depth tools. An active ZoomInfo SalesOS or Copilot subscription with API access is required.

Tools

Prerequisites

• Active ZoomInfo SalesOS or Copilot subscription with API access enabled
• An MCP-compatible client (Claude Desktop, Claude Code, Cursor, Windsurf, etc.)
• For Claude Code: a ZoomInfo MCP application with client_id, client_secret, and redirect URI http://localhost:8080/callback (authentication type: Authorization Code)

Claude Desktop / Cursor / Windsurf (connector flow)

1. Open your AI client's Settings, then Connectors or Integrations.

2. Add a new MCP server connection and enter the URL:

   https://mcp.zoominfo.com/mcp
   

3. Save and click Connect to ZoomInfo.

4. Sign in with your ZoomInfo credentials (or SSO) and approve the OAuth permissions.

Cursor mcp.json example

{
  "mcpServers": {
    "zoominfo": {
      "url": "https://mcp.zoominfo.com/mcp"
    }
  }
}

Claude Code

Register the server with the Claude Code CLI:

claude mcp add --transport http \
  --callback-port 8080 \
  --client-id <your-client-id> \
  --client-secret \
  zoominfo https://mcp.zoominfo.com/mcp

Then run /mcp inside Claude Code to trigger the OAuth browser flow and sign in to ZoomInfo. Credentials are stored in your OS keychain, not in plaintext.

• Official, provider-hosted server maintained by ZoomInfo with no self-install required.

• Works with major MCP clients including Claude Desktop, Claude Code, Cursor, and Windsurf.

• Requires an active ZoomInfo SalesOS or Copilot subscription with API access; not usable on free tiers.
• Consumes ZoomInfo Data Credits and AI Credits, so high-volume agent workflows can incur meaningful cost.
