ChatGPT
How to connect ZoomInfo MCP to ChatGPT via the app marketplace. Works on all tiers, including free plans.
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 orients from your GTM context and only runs after you approve:
(Use the ZoomInfo MCP tools if available; otherwise use the GTM CLI.) I just connected ZoomInfo. Help me get real value from my ZoomInfo credits today - I want to spend them on the most valuable first thing to do. Don't run anything I haven't picked yet. 1. Call get_gtm_context - it's free (no credits). Use whatever it returns, plus my company name and email domain, to work out what we sell and who we target. Don't ask me, just figure it out. 2. Say it back in one line: "You're <Company>, selling <offering> to <ICP>." Check I agree. Once I confirm, save it by calling update_gtm_context so my GTM context is set for next time. If I'm not an admin, the save will fail - that's fine, just continue. 3. Offer me 3–4 concrete first actions grounded in my context - e.g. prep for a meeting this week, find companies matching our ICP, surface accounts showing buying intent, map the buying committee at a target account. Let me pick one, or tell you my own goal. 4. Only once I've chosen: tell me which ZoomInfo tools you'll run and roughly how many credits it'll cost. Go ahead - that's what they're for. Just tell me the cost before running so I stay in control. Keep it fast. A quick, real win - not a tour and not a list I didn't ask for.

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: MCP requires bulk data credits. Contact your ZoomInfo admin or ZoomInfo representative if you're unsure whether your account has bulk credits enabled.
