ZoomInfo MCP Server Review 2026: Tools, Credits, Limits

The ZoomInfo MCP server is ZoomInfo's official MCP server at https://mcp.zoominfo.com/mcp. It lets Claude, ChatGPT, Microsoft Copilot and other AI tools search, enrich and research ZoomInfo company and contact data. It costs nothing extra on a subscription with data credits, a free account gets 1,000 data and 1,000 AI credits once, and enrichment costs 1 data credit per new record.

Facts checked October 1, 2026. Every ZoomInfo fact below comes from ZoomInfo's MCP documentation on gtm.ai, its MCP solution page and its Pipeline blog, each read on October 1, 2026. ZoomInfo's AI documentation lives on gtm.ai, a ZoomInfo domain. We did not run a prospecting project through ZoomInfo's MCP for this review, so there are no accuracy numbers here.

Does ZoomInfo have an MCP server?

ZoomInfo has an official, hosted MCP server. ZoomInfo's docs give the endpoint as https://mcp.zoominfo.com/mcp for Streamable HTTP connections, and it answered with an authentication challenge when we sent it a request on October 1, 2026. Each person signs in with their own ZoomInfo login over OAuth; teams that need shared access can use a service account instead.

ZoomInfo ships the server as native apps and connectors. Its Pipeline blog post of July 27, 2026 lists Claude, ChatGPT (every ChatGPT tier), Microsoft Copilot Studio, Perplexity on paid plans, Slack, Amazon Quick and Gemini Enterprise, plus plugin or custom entries for Claude Code, Codex and Cursor. ZoomInfo also publishes an MCP plugin on GitHub and a Microsoft connector.

What can the ZoomInfo MCP server do?

ZoomInfo's MCP server is built for account and contact research. ZoomInfo's tools reference lists 23 tools in five groups:

• Search: Lookup (valid filter values), Search Companies, Search Contacts, Search Intent, Search Scoops.
• Enrich: Enrich Companies and Enrich Contacts (up to 10 records per call), Enrich Company Signals (intent, news and scoops for up to 10 companies).
• Discover: Find Similar Companies, Find Similar Contacts, Find Recommended Contacts.
• Audiences: Browse Audiences, Get Audience, Upsert Audience, Manage Audience Columns, Manage Audience Rows, Audience Analysis.
• Research and context: Account Research, Contact Research, Conversation Intelligence, Browse Engagements, GTM Context, Update GTM Context.

ZoomInfo's solution page says Enrich Contacts adds verified email, phone and professional attributes. Its docs put coverage at 100M+ companies and 500M+ contacts. Intent tools only work if Intent Topics are configured in your subscription.

ZoomInfo's tools reference has changed since our October 1 check. On November 4, 2026 it also listed Submit Feedback, a free tool that sends ZoomInfo a data problem or a feature request, and it marked the older Enrich Intent, Enrich News and Enrich Scoops tools as superseded by Enrich Company Signals.

How do you connect ZoomInfo to Claude or ChatGPT?

ZoomInfo connects through each AI client's connector store. ZoomInfo's three steps: open the connectors or apps menu in your AI client, find and enable ZoomInfo, then sign in with your ZoomInfo credentials over OAuth. In Claude Code, Cursor or another developer client, you add https://mcp.zoominfo.com/mcp as a remote server.

Three details matter for admins. ZoomInfo's Admin Portal enables or disables MCP per user. Each user needs a personal ZoomInfo account, and ZoomInfo's FAQ says shared logins lose personalization in the research agents. And the tool list refreshes at session start, so restart the session when ZoomInfo adds a tool.

ZoomInfo MCP setup, step by step

These steps come from ZoomInfo's client setup pages (checked November 4, 2026).

Claude:

1. Open Settings, then Connectors.
2. Search the connector directory for ZoomInfo and select it.
3. Sign in with your ZoomInfo login.
4. Start a new chat and ask: "What ZoomInfo tools do you have access to?"

The same Connectors screen lets you switch single ZoomInfo tools off, for example to stop enrichment calls from spending credits.

ChatGPT (every tier, including free plans):

1. Click Apps in the side panel.
2. Search for ZoomInfo and click Connect.
3. Sign in with your ZoomInfo login, then ask which ZoomInfo tools you have.

Claude Code:

claude plugin install zoominfo@claude-plugins-official

Then run /mcp in a session, pick zoominfo and choose Authenticate. The plugin also adds ZoomInfo's skills, such as /account-research and /build-list. For the tools alone, run claude mcp add --transport http zoominfo https://mcp.zoominfo.com/mcp and authenticate the same way.

Any other MCP client: add a custom server with the URL https://mcp.zoominfo.com/mcp, pick Streamable HTTP and sign in with OAuth, leaving any client ID, client secret and header fields blank. Cursor connects through the mcp-remote bridge, and a few command-line clients need an app you register with ZoomInfo first.

How much does the ZoomInfo MCP server cost?

The ZoomInfo MCP server costs nothing on top of a ZoomInfo subscription. ZoomInfo's Pipeline post says it comes with every ZoomInfo subscription at no additional cost, and its docs name Sales, Copilot, Studio and ZI Lite subscriptions with data credits available.

ZoomInfo also runs a free entry point. Its docs say a new account gets "1,000 data credits and 1,000 AI credits" once, at signup. ZoomInfo's solution page advertises a smaller offer of 100 free AI and data credits for Claude and ChatGPT users, so the two pages disagree; the docs give the larger and more specific figure.

ZoomInfo publishes no list price for its subscriptions. Its pricing page served us no figure on August 22, 2026 and refused our request on October 1. The best public benchmark is Vendr's buyer guide: a median of $33,500 a year across 1,574 recorded purchases, from $7,220 to $155,730. Our ZoomInfo pricing guide has the full breakdown.

What does a prospecting session use in ZoomInfo credits?

ZoomInfo charges two kinds of credit through MCP. Data credits pay for enrichment: 1 credit per new record, 1 per new company signal, and 1 per new record loaded into an audience. AI credits pay for research agents: ZoomInfo says most Account Research and Contact Research calls cost 5 to 15 credits, and Conversation Intelligence at least 9.

A typical session that searches for 25 contacts, enriches all 25 and runs Account Research on 5 target accounts uses 25 data credits (three enrichment calls at the 10-record cap) and about 25 to 75 AI credits. Search, lookup and similar-contact discovery are free. Re-enriching a record is free for 12 months, because ZoomInfo keeps an enriched record "under management" for that window.

Updates from ZoomInfo's docs and pricing page, checked November 4, 2026:

• Search can cost credits. A search is free unless the call sets redeem: true, which charges 1 data credit per new record returned, up to 25 a page.
• Research cost varies. ZoomInfo says the cost of Account Research and Contact Research scales with how much context the answer needs. GTM.AI's pricing page puts an account research prompt at about 9 to 12 AI credits.
• No cost preview. ZoomInfo shows no cost preview before a tool call. Its starter prompt asks the AI to estimate credits and check with you first.
• Per-user caps. Admins can cap data and AI credits per user in the Admin Portal, under Users, then User Management.

Does ZoomInfo have a Copilot add-on price?

ZoomInfo does not publish a price for Copilot or any other edition. Copilot is one of the subscriptions ZoomInfo's MCP docs name as eligible, alongside Sales, Studio and ZI Lite. Any Copilot figure you see online is a third-party report or a quote, so ask ZoomInfo for a written quote and check it against Vendr's ranges before you sign.

What are the limits of ZoomInfo's MCP server?

ZoomInfo's docs are unusually open about the limits:

• No CRM write-back. The docs say the MCP server "doesn't write to your CRM or run bulk exports and batch enrichment pipelines." Writes are limited to ZoomInfo audiences and GTM context. ZoomInfo's product for writing data into HubSpot and Salesforce is Enrich, covered in our ZoomInfo Enrich guide.
• Ten records per enrichment call and one account or contact per research call. A 500-row list takes 50 calls.
• Recurring monthly credits don't work. "Some older subscriptions carry recurring monthly credits," and MCP can't draw from them. Those accounts need bulk data credits first.
• No sending. There are no sequence or email tools, so outreach happens in another product.
• No published rate limit on the pages we read.
• Annual contracts. Outside the free credits, access rides on a ZoomInfo subscription with no public price.
• Published ceilings. ZoomInfo's limits page, checked November 4, 2026, lists 10 records per enrich call, 25 records a page on a search with redeem: true, 50 rows per Manage Audience Rows call, 50 topics per Search Intent call, and 200,000 rows per audience unless your plan sets another.

Who is the ZoomInfo MCP server good for?

ZoomInfo's MCP server is the strongest pick for enterprise account executives and account managers who already pay for ZoomInfo and want research inside their AI assistant: briefings on an account, buying signals, recent scoops and what was said on past calls. ZoomInfo is the only server in this review that ships intent search and scoops as tools, next to its research agents and conversation intelligence. The 12-month free re-enrichment window also suits teams that revisit the same accounts all year.

It fits less well for small teams without a ZoomInfo contract, for teams that want the assistant to write into the CRM or a sequencer, and for anyone building lists of hundreds of contacts at once, where 10 records a call gets slow.

How does ZoomInfo MCP compare to Apollo, Clay and Clu MCP?

The four servers below are the ones B2B buyers ask about most. Facts come from each vendor's own docs, read October 1, 2026.

Our Apollo MCP server review and Clay MCP server review cover the other two in the same depth, and the best MCP servers for sales and GTM covers CRM and sequencer servers too.

Where does Clu's MCP server fit next to ZoomInfo?

Clu publishes this page, so treat this section as a disclosed vendor entry. Clu runs a remote MCP server at mcp.cleanlist.ai/v1/mcp with 30+ tools for people and company search, enrichment (verified work email and phone number), lead lists and export, with names such as search_people, search_companies and enrich_person. You describe the list in plain English and the agent turns it into search filters. Search is free; a verified work email costs 1 credit and a phone number 10, and a lookup that finds nothing costs nothing. Each lookup runs a waterfall across 25+ data providers. Our own 500-lead benchmark measured 98% verified work email and 85% phone numbers.

Clu sells monthly plans with public prices, and MCP is included from Starter at $49 per seat a month. The 14-day Pro trial includes MCP with 250 credits and the Free plan does not, so ZoomInfo's 1,000 free credits are the larger allowance for trying a sales-data MCP server at no cost. Clu has no intent data today. It has agents, a Research skill and built-in Sequences, but it is not yet in the Claude or ChatGPT directories: you add it in Claude as a custom connector and paste the OAuth client ID Clu gives you into the advanced settings.

Pick ZoomInfo if you already pay for it and want research, signals and intent inside your assistant. Pick Clu if you want verified emails and phone numbers for a list, on a monthly plan with a published price. The Clu MCP product page shows the setup, and our plans are on the pricing page.

Frequently asked questions

Is the ZoomInfo MCP server read-only?

Mostly. ZoomInfo's docs say it does not write to your CRM or run bulk exports. The only writes are saving audiences, loading your own records into an audience, and updating GTM context.

Does ZoomInfo MCP return phone numbers?

Yes. ZoomInfo's solution page says Enrich Contacts adds verified email and phone data. Each newly enriched record costs 1 data credit.

Can I use ZoomInfo MCP without a ZoomInfo subscription?

Yes, to start. ZoomInfo's docs say a new account gets 1,000 data credits and 1,000 AI credits once at signup. After those run out you need a subscription with bulk data credits.

What is gtm.ai?

gtm.ai is the ZoomInfo domain that hosts its MCP documentation and AI products. The MCP endpoint itself is on zoominfo.com.

What is the ZoomInfo MCP server URL?

The ZoomInfo MCP server URL is https://mcp.zoominfo.com/mcp, typed exactly, with no trailing slash. It uses the Streamable HTTP transport and OAuth sign-in, with no static token or header (checked November 4, 2026). Every client connects to the same URL, whether you add ZoomInfo from a connector directory or as a custom server.

How do I connect ZoomInfo MCP to Claude?

In Claude, open Settings, then Connectors, search for ZoomInfo, select it and sign in with your ZoomInfo login. In Claude Code, run claude plugin install zoominfo@claude-plugins-official, then /mcp, pick zoominfo and authenticate (checked November 4, 2026). You need your own ZoomInfo login with data credits, because admin-only seats and subscriptions with only recurring monthly credits cannot use MCP.

Does ZoomInfo MCP work in ChatGPT?

Yes. ZoomInfo is listed in ChatGPT's app marketplace, and ZoomInfo says setup works on every ChatGPT tier, including free plans (checked November 4, 2026). Click Apps in the side panel, search for ZoomInfo, click Connect and sign in with your ZoomInfo login.

Is the ZoomInfo MCP server on GitHub?

The server itself is hosted by ZoomInfo, so there is no server code to run. ZoomInfo's GitHub organization publishes zoominfo-mcp-plugin, an MIT-licensed repo that registers the hosted server for Claude, Codex and Cursor and adds 14 skills such as account-research, build-list and meeting-prep (checked November 4, 2026). It stores no API keys, because you sign in with your ZoomInfo account over OAuth. The same organization hosts gtm-ai-cli, the GTM command-line tool our GTM.AI explainer covers.

What is the difference between ZoomInfo MCP and the ZoomInfo API?

ZoomInfo MCP is for a person asking questions inside an AI tool, the REST API is for application code, and the GTM CLI is for scripts and scheduled jobs. All three draw on the same credit pools (checked November 4, 2026). The API enriches up to 25 records per call against MCP's 10, and ZoomInfo sends bulk exports and pipelines to the web app, the REST API or the GTM CLI. Our ZoomInfo API guide covers its endpoints, OAuth setup and rate limits.
