Zoominfo Mcp Plugin MCP Server

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"
    }
  }
}

Client Support

This repository includes metadata for multiple plugin-capable client environments:

Install or register the plugin according to your client's plugin or MCP workflow. For local development, clone this repository and point your client at the repo root or relevant manifest path.

git clone https://github.com/Zoominfo/zoominfo-mcp-plugin.git

Skills

Skills are task-focused playbooks the agent follows to return structured outputs (briefs, tables, scores, emails) instead of raw tool JSON. Trigger them with /skill-name or plain language ("prep me for a meeting with Acme"); the agent can also select the right skill automatically when your request matches.
