ZoomInfo MCP with Claude: Faster Prospect Research and Contact Enrichment
The short answer
Claude works with ZoomInfo through the Model Context Protocol (MCP), an open standard that acts as a secure adapter between the two. Once connected using OAuth sign-in, Claude can search companies and contacts, enrich records and look up recent news, based on permissions your organisation sets and approves.
What is Zoominfo?
ZoomInfo is a business-to-business database of companies and professional contacts. Sales, marketing and revenue teams use it to find potential customers, check contact details and keep customer records up to date. It helps teams decide who to contact, what to say and when, so that sales effort goes to the right prospects.
How Claude connects to Zoominfo through MCP
The Model Context Protocol (MCP) is an open standard that lets Claude use other software securely. Think of it as a universal adapter between Claude and a tool like ZoomInfo. The organisation decides exactly which information Claude may read and which actions it may take.
Once ZoomInfo is connected, Claude can typically search for companies by industry, size or location, find contacts by role, enrich partial records and look up recent company news. Staff can ask for these things in ordinary language rather than building complicated search filters.
Permissions and approvals keep people in charge. Access is granted through OAuth sign-in with least-privilege settings, so Claude only sees what it needs. Consequential actions, such as adding records to a campaign, can require a person to approve them first, and every request is logged for review.
What you can automate
Prospect list building
A sales manager asks for mid-sized logistics companies in the Midlands with recent funding. Claude searches ZoomInfo, returns a shortlist with key contacts and summarises why each account may be a good fit. The team reviews the list before outreach starts, saving hours of manual filtering.
Contact enrichment for the CRM
Sales operations teams often hold records with missing job titles or phone numbers. Claude can check incomplete contacts against ZoomInfo and propose updated details. A person reviews the changes before they are written back, which typically improves data quality and reduces bounced emails.
Account research before meetings
An account executive preparing for a call asks for a brief on a prospect. Claude gathers company size, recent news, key decision makers and likely pain points from ZoomInfo, giving the executive a concise summary in minutes rather than an hour of browsing.
News-triggered outreach
Marketing teams want to reach companies when something changes, such as a leadership hire or expansion. Claude can search recent news for target accounts and flag relevant events, so the team can time personalised messages around genuine business moments.
Territory and segment analysis
Revenue leaders need to understand where their total addressable market sits. Claude can summarise account counts by region, industry and size from ZoomInfo data, helping leaders plan territories and set realistic targets for each team.

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom must follow their own rules on commercial email and personal data, and we design workflows to respect them.

Frequently asked questions
What does the ZoomInfo MCP server do?
The ZoomInfo MCP server acts as a secure bridge between ZoomInfo and AI tools such as Claude. It allows Claude to find companies, enrich contacts, research prospects and search news using natural language, within the permissions you grant. It does not replace your ZoomInfo account or its own controls.
Is connecting ZoomInfo to Claude secure?
Security depends on how the connection is configured. We use OAuth sign-in, least-privilege access and audit logs, and we require human approval for actions that change records or start outreach. Your administrator stays in control of who can use the connection and what it can reach.
What can Claude do with ZoomInfo once connected?
Typically, Claude can search for companies and contacts by criteria you describe, enrich partial records, summarise account information and look up recent company news. It can then pass results into your CRM or other systems, subject to the approvals you set.
How long does setup take?
Many organisations are running a first workflow within a few weeks. The timeline depends on how many systems are involved, how complex the approval rules are and how much testing your data needs. We confirm a realistic schedule after the free automation audit.
Which ZoomInfo plan or permissions do I need?
Access depends on the ZoomInfo subscription and user permissions your organisation already has. Generally, the connecting user needs permission to use the data and API features the workflow relies on. We check these requirements during the audit so there are no surprises.
