ZoomInfo MCP endpoint and transport

https://mcp.zoominfo.com/mcp

Transport: Streamable HTTP
Docs: Official ZoomInfo MCP docs

Connect ZoomInfo without code

ZoomInfo's docs confirm it works in Claude and ChatGPT. You don't need a terminal or a config file. Check ZoomInfo's docs first: some vendors give you a personal URL or an API key to use in place of the plain endpoint.

Claude (web and desktop app)

If ZoomInfo shows up when you browse connectors in Claude, connect it from there instead. That skips steps 2 to 4.

In Claude, open Customize → Connectors.
Click + Add, then Add custom connector.
Name it “ZoomInfo”, paste the server URL https://mcp.zoominfo.com/mcp, and click Continue.
Review the sign-in settings Claude detected and click Add.
Click Connect and sign in to ZoomInfo. Then ask Claude something like “What can the ZoomInfo connector do?”

On Team and Enterprise plans, an Owner adds the connector first under Organization settings → Connectors → Add → Custom → Web. Each person then connects it from Customize → Connectors. Free plans can add one custom connector.

ChatGPT

If ZoomInfo has its own plugin in ChatGPT's directory, install that instead.

Go to chatgpt.com/plugins.
Select +, then Add custom MCP server. If you don't see it, your plan or workspace settings may not allow custom servers, so ask your workspace admin.
Enter a name and description. Under Connection, paste the server URL https://mcp.zoominfo.com/mcp.
Set up sign-in, read the warning, and select I understand and want to continue.
Select Create as a plugin. In a new chat, type @ and pick ZoomInfo.

Steps from the OpenAI developer docs: developers.openai.com, checked 2026-10-16

From ZoomInfo's docs: Native connectors in the Claude directory and ChatGPT app marketplace (ChatGPT works on all tiers including free); Claude Code and Codex via official plugin or custom MCP; Cursor and VS Code Copilot via custom MCP entry. MCP cannot draw from recurring monthly credits that some older subscriptions carry.Source: gtm.ai, checked 2026-10-16

Developer setup (Claude Code, Cursor)

Add this to .mcp.json (Claude Code, project root) or ~/.cursor/mcp.json (Cursor). Remove the // comment line if your client requires strict JSON.

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

Add the endpoint to your client config (above), or as a custom connector in Claude.
Complete the OAuth sign-in. In Claude Code, run /mcp and pick the server.
Test it with a prompt like: “List the tools the ZoomInfo MCP server exposes.”

ZoomInfo MCP authentication

OAuth 2.0 (Authorization Code with PKCE for user sign-in; Client Credentials for service accounts)

Sign in with OAuth in your client (run /mcp in Claude Code). Do it once interactively, and the client stores and refreshes the token.
