Connect your AI client to ZoomInfo and access powerful B2B intelligence through natural language. Find companies and contacts, enrich records, discover buyer intent signals, build audiences, and generate comprehensive account and contact research without leaving your conversation.

This guide explains how to connect the ZoomInfo MCP server to both AI coding assistants (such as Claude Code, OpenAI Codex, Cursor, Antigravity, and other MCP-compatible clients) and consumer AI applications (such as Claude.ai, Claude Desktop, and ChatGPT).

Before You Begin

• A ZoomInfo license (GTM.ai self-serve or Enterprise) is required.
• Your ZoomInfo plan, API limits, credits, and feature availability apply to MCP usage.
• AI agents can only perform actions allowed by your ZoomInfo account.
• Available data and AI credits for enrichment or credit-consuming actions.
• Compatible with MCP clients supporting Streamable HTTP and OAuth.
• A browser for the one-time OAuth sign-in.
• Model training turned off in your AI account or client settings.

Coding Agent Setups

Claude Code

ZoomInfo is available as an official plugin in Anthropic's marketplace, so you can connect using either the Plugin route or the standard MCP route.

If you're using the Anthropic plugin route, run the following command in the terminal where you configured Claude Code:

claude plugin install zoominfo@claude-plugins-official

or, If you're using the custom MCP route, run the following command in the terminal where you configured Claude Code:

claude mcp add --transport http zoominfo https://mcp.zoominfo.com/mcp

After adding the ZoomInfo MCP server using either the Plugin or MCP route, open Claude Code terminal and run:

/mcp

This will launch the ZoomInfo sign-in flow in your browser. Sign in using your ZoomInfo credentials or your organization's SSO.

After authentication completes and you're redirected back to Claude Code, the ZoomInfo MCP server will appear as Connected, and all available tools and skills will be ready to use.

If you have multiple MCP servers configured, select ZoomInfo, then choose Authenticate.

OpenAI Codex

ZoomInfo ships as an official Codex plugin, so you can connect using either the Plugin route or the Custom MCP route.

If you're using the Plugin route, in the Codex app open Plugins (or in the CLI, run codex then /plugins to open the plugin browser), search for ZoomInfo, and install it:

Plugins → search "ZoomInfo" → Add to Codex (app) or Install plugin (CLI)

or, If you're using the Custom MCP route, Run in your terminal:

codex mcp add zoominfo --url https://mcp.zoominfo.com/mcp

After adding the ZoomInfo MCP server using either the Plugin or Custom MCP route, Codex prompts you to sign in the first time it uses the server:

codex mcp login zoominfo

This launches the ZoomInfo sign-in flow in your browser. Sign in using your ZoomInfo credentials or your organization's SSO. After authentication completes, ZoomInfo will appear as connected, and all available tools will be ready to use.

Cursor

Open Cursor settings and add a new MCP server, or edit ~/.cursor/mcp.json directly, then add the zoominfo entry to your mcpServers block:

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

Restart Cursor so it picks up the new server entry. The first time Cursor uses the ZoomInfo server, it opens the ZoomInfo sign-in flow in your browser. Sign in using your ZoomInfo credentials or your organization's SSO and approve access.

VS Code Microsoft Copilot

Create a .vscode/mcp.json file in your workspace:

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

Open the Command Palette (Ctrl+Shift+P on Windows/Linux or Cmd+Shift+P on macOS) and run:

MCP: List Servers

Select the ZoomInfo MCP server and start it. When prompted, complete the OAuth sign-in flow to authorize the connection.

Antigravity

Follow the Antigravity instructions for connecting custom MCP servers and add the following to your mcp_config.json:

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

Save the configuration. Antigravity prompts you to complete the OAuth flow to connect your ZoomInfo account.

If you're using an MCP client that isn't covered in the examples above, you can connect it using the ZoomInfo MCP endpoint. Ensure that your MCP client supports OAuth 2.0, as it's required to authenticate and access the ZoomInfo Platform.

Chat Application Setups

This section focuses on connecting the ZoomInfo MCP server with consumer AI Chat applications such as ChatGPT, Claude Desktop, Claude Cowork, Claude.ai, Perplexity, and other MCP-compatible AI clients.

If you're looking to connect developer tools such as Cursor, Visual Studio Code, OpenAI Codex, or your own custom MCP client, follow the dedicated coding agent Setup guide instead.

ZoomInfo is available through the Claude Connector Marketplace, ChatGPT App Marketplace, and Perplexity Connectors, making it easy to connect ZoomInfo with your preferred AI chat application.

Claude

If you're using Anthropic's Claude.ai, Claude Desktop, or Claude Cowork, ZoomInfo is available as a native connector.

Open Settings, then Connectors, search ZoomInfo in the connector marketplace and click connect. Sign in with your ZoomInfo credentials when prompted.

ChatGPT

If you're using OpenAI's ChatGPT.com or ChatGPT Desktop, ZoomInfo is available as a native connector.

Open the Apps panel, search for ZoomInfo and click connect. Sign in with your ZoomInfo credentials when prompted.

Perplexity

If you're using Perplexity.ai or Perplexity Computer, ZoomInfo is available as a native connector.

Open Connectors, search for ZoomInfo and click Add Connector. Sign in with your ZoomInfo credentials when prompted.
