ZoomInfo MCP Plugin

Use ZoomInfo go-to-market intelligence from LLM clients that support MCP servers, plugin manifests, and/or skills.

This repo packages ZoomInfo's hosted MCP server with client-specific plugin metadata and task-focused skills for sales, marketing, and revenue workflows. It is intended to work across supported LLM clients rather than being tied to a single provider.

What It Enables

• Find companies, contacts, and buying committee members
• Enrich account, lead, and contact records with business information
• Build targeted account and contact lists
• Identify similar companies, similar contacts, and recommended contacts
• Research accounts, competitors, markets, intent signals, and technology stacks
• Prepare for sales calls, prioritize inbound leads, and personalize outreach
• Size TAM and refine ICP or territory filters

Try Asking

• "Help me prepare for a meeting with Apple's VP of Marketing this afternoon."
• "Build me a list of SaaS companies in the UK with 200-500 employees using Salesforce."
• "Find companies showing high buyer intent on data observability in the last 30 days."

Prerequisites

• An LLM client or agent environment that supports MCP and/or local plugin manifests
• A ZoomInfo account with the appropriate API access and product entitlements

MCP Server

The plugin registers ZoomInfo's hosted MCP server (https://mcp.zoominfo.com/mcp). Authentication is handled through your ZoomInfo account via OAuth — no API keys are stored in this repo. Clients connect over HTTP and complete the OAuth flow natively. All clients share the registration defined in .mcp.json:

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