# FAQ & Troubleshooting > Common questions about ZoomInfo MCP and steps to resolve authentication, credit, and compatibility issues. **Date:** 2026-03-19 **Source:** https://gtm.ai/docs/mcp/faq --- ## General ### Does MCP give me access to more data than my current ZoomInfo package? No. MCP respects your existing package entitlements. You access the same data through your AI tool that you'd access in the ZoomInfo web app. Different packages return different fields, and this is enforced at the API level. ### Can multiple users share a single ZoomInfo login for MCP? This is technically possible but strongly not recommended. Much of the value in context agents like Account Research comes from user-level context: your accounts, your CRM relationships, and your ZoomInfo platform activity. A shared login loses all of that personalization. Each user should authenticate with their own ZoomInfo credentials. ### Does MCP support bulk exports or CRM write-back? No. MCP is designed for interactive AI-assisted workflows. It is not built for bulk data exports, CRM write-back, batch enrichment pipelines, or administrative tasks. For those use cases, use the ZoomInfo web app, REST API, or existing automation integrations. ### When ZoomInfo adds new tools, do I need to do anything? No. New tools are automatically available at the start of your next session. The AI client calls the tool list on each new session and receives an up-to-date set of tools. ### Can I control which ZoomInfo tools the AI is allowed to use? Yes. Most MCP clients let you enable or disable individual tools in the connector settings. You can also influence tool selection by specifying which tool you want in your prompt. ### Is Claude Code (the CLI) supported? Yes. Register the ZoomInfo MCP server with `claude mcp add` after creating an MCP App in the [ZoomInfo Developer Portal](https://developer.zoominfo.com). Full walkthrough in the [Claude Code setup guide](/guides/how-to-connect-to-zoominfo-mcp-in-claude-code). ### Is OpenAI Codex supported? Yes. Add a Custom MCP entry in Codex Settings pointing at `https://mcp.zoominfo.com/mcp` over Streamable HTTP, then complete the ZoomInfo login. Full walkthrough in the [Codex setup guide](/guides/how-to-connect-to-zoominfo-mcp-in-codex). ## Credits ### Why isn't MCP working even though I have a valid ZoomInfo login? MCP requires **bulk data credits** and does not work with recurring monthly credits. If your account only has monthly credits, contact your ZoomInfo admin to enable bulk credits. ### Will I be charged twice if I enrich the same record in MCP and again in Studio? No. Records Under Management (RUM) is respected across all ZoomInfo surfaces. Once a record is enriched anywhere in the platform, it won't be charged again for 12 months regardless of which surface accesses it next. ### Can my admin cap how many credits I can use through MCP? Yes. Admins can set bulk data credit limits and AI action credit limits per user in the Admin Portal. These limits are enforced when users connect through MCP. ### Why was I charged for a record I've already seen in Copilot? Viewing data in Copilot doesn't consume bulk credits. Enriching via MCP does, because the data is pulled into the AI tool's context (equivalent to an export). If the record was already enriched by someone in your organization within the past 12 months, RUM applies and no credit is charged. ## Troubleshooting ### I'm getting a 'Forbidden' error on search or enrich. Try disconnecting and reconnecting your ZoomInfo account in your AI client's connector settings. If the issue persists, contact ZoomInfo support with your user ID. ### I'm getting 401 (unauthorized) errors. Verify you're using a supported AI client and that your ZoomInfo credentials are correct. Try logging out of ZoomInfo in the connector settings and logging back in. Confirm you're using your personal ZoomInfo login, not a shared or admin-only account. ### I can't find ZoomInfo in ChatGPT. ZoomInfo is listed in the ChatGPT app marketplace. Open **Apps** in the side panel and search for "ZoomInfo." If it doesn't appear, try refreshing the page or starting a new session. See the [ChatGPT setup guide](/docs/mcp/clients/chatgpt) for full instructions. ### A tool I expected isn't showing up. Start a new session. Tool lists are refreshed at session start. Ask the model: *"What ZoomInfo tools do you have access to?"* to confirm what's available. If a tool is missing, verify your ZoomInfo package includes the underlying data (e.g., intent data requires Intent Topics to be configured in your subscription). ### What do I do if a query falls outside the scope of available tools? The AI model will tell you. We're also building a feedback mechanism so the model can log requests for functionality not yet available. This feeds directly into our tool roadmap.
