How to connect ZoomInfo MCP to ChatGPT via the app marketplace. Works on all tiers, including free plans.

·Rowan BaileyRowan BaileySenior Director, Product

Overview

ZoomInfo is listed in the ChatGPT app marketplace. Once connected, ChatGPT can invoke ZoomInfo tools based on your prompts or when you explicitly ask it to use ZoomInfo. Setup works on all ChatGPT tiers, including free plans.

Setup

Open the Apps panel

Click Apps in the ChatGPT side panel.

Find ZoomInfo

Search for ZoomInfo and click Connect.

Authenticate

Sign in with your ZoomInfo credentials when prompted.

Verify the connection

Start a new conversation and ask: "What ZoomInfo tools do you have access to?"

Next: run your first session. Once ZoomInfo is connected, paste this into a new ChatGPT conversation. It starts from your saved GTM context and asks before it spends credits:

First GTM session
(Use the ZoomInfo MCP tools if available; otherwise use the GTM CLI. Use the tool schema or CLI help for supported commands.)

I just connected ZoomInfo. Help me complete the job below.

1. Read my saved business context with get_gtm_context, or the CLI equivalent. This read is free. Use the returned offerings, ICP, and role to frame the work. If context is missing, continue with the information we have. Save changes only if I explicitly ask; a first briefing does not require updating shared business context.

2. Prepare a connected account briefing. Ask me only which company or domain to brief if I haven't named one. Use the account and decision already in this conversation when available. Connect the account's available CRM history, including stage and status, with recent customer conversations and external buying signals. Use Account Research, and add Browse Engagements, Conversation Intelligence, or company signals when the briefing needs more evidence.
   Return a short briefing: where things stand, what changed, what remains unresolved, and one recommended next action. Cite the source and date for each material fact when returned. Distinguish the recommendation from the evidence.

3. Before calling a tool, check its schema or documented inputs rather than guessing at parameters. Ask only for missing inputs, in a single message, then name the tools and give a credit estimate if supported by their documentation. Label it as an estimate: actual charges depend on records and work done. Ask for approval once before paid research, then complete the selected job.

If a tool call comes back "No approval received" or a similar permission response, say so plainly, name the tool, and continue with the remaining steps. Don't retry the same call hoping for a different result, and don't invent an approval that didn't happen.

Include a source-coverage note of no more than 3 lines. Separate an unavailable or unauthorized source from a successful search with no matching records. If connection status is unknown, say so. Never infer "no customer history" from an empty result. Continue with available evidence and identify what is missing; use https://gtm.ai/guides/connect-customer-context for source setup.

Recommend CRM changes as drafts. Applying them requires an available, separately connected CRM workflow and my authorization. Do not claim a CRM update was made by ZoomInfo research tools.

Tool Behavior in ChatGPT

ChatGPT selects the appropriate ZoomInfo tool based on your request. You can guide tool selection by being specific in your prompts, or by saying "use ZoomInfo to..." followed by your request.

You can also prime ChatGPT to use ZoomInfo tools by clicking the + in the chat window, hovering over More, and selecting ZoomInfo. ChatGPT will still reach for ZoomInfo tools without this step, based on conversation context or if you explicitly ask.

New ZoomInfo tools become available automatically at the start of each new session.

Troubleshooting

Can't find the app: open Apps in the side panel and search for "ZoomInfo." If it does not appear, try refreshing the page or starting a new session.

Authentication errors: confirm you're using your personal ZoomInfo credentials. Admin-only ZoomInfo accounts cannot authenticate to MCP.

Credit errors: check which credits your account has. MCP can't draw from recurring monthly credits, which some older subscriptions carry; free accounts and bulk data credits work. See Which credits MCP uses.
