FullEnrich MCP with Claude: Faster Verified Lead Contact Data for Sales
The short answer
Claude works with FullEnrich through the Model Context Protocol (MCP), an open standard that acts as a secure adapter between the two. Once connected with an API key, Claude can ask FullEnrich to enrich lead records, find and verify business email addresses and look up phone numbers, all from plain-English instructions, with permissions your organisation controls.
What is Fullenrich?
FullEnrich is a B2B contact enrichment platform. It gathers business email addresses and phone numbers from more than 15 data vendors and helps teams find and verify contact details for prospects. Sales development representatives, account executives, revenue operations teams and marketing managers typically use it to fill gaps in their lead lists and keep outreach databases accurate before campaigns begin.
How Claude connects to Fullenrich through MCP
The Model Context Protocol (MCP) is an open standard that lets Claude securely use other software, reading information and taking actions with permissions the organisation controls. Think of it as a universal adapter between Claude and the tool. For FullEnrich, the connection can use the platform's MCP server or a direct API, both authenticated with an API key that your team issues and can revoke at any time.
Once connected, Claude can typically read the lead details you provide, request enrichment for a list of prospects, look up verified email addresses and phone numbers, and return the results in a format your team can use. A sales representative might simply ask for contact details for ten named decision makers and receive a checked list in return.
Permissions and approvals keep people in charge. We set up access with least-privilege rules, so Claude only reaches the functions it needs. Consequential actions, such as writing new records into your CRM or starting an outreach sequence, can require a person to review and approve them first. Audit logs record what was requested and by whom.
What you can automate
Enriching new inbound leads
When a prospect fills in a web form, Claude can use FullEnrich to find a verified work email and phone number for that person and their company. Sales teams get a more complete record within minutes, rather than waiting for manual research. Representatives can then follow up while the enquiry is still fresh, which often improves response rates.
Cleaning up an outdated prospect list
Long-running prospect databases often contain bounced emails and people who have changed roles. Claude can work through a list in batches, request fresh verified contact data from FullEnrich and flag records that could not be confirmed. Operations staff review the flagged items, so the final list is cleaner before a campaign goes out.
Building targeted outbound lists
A business development manager might describe the ideal buyer in plain language, such as finance directors at mid-sized logistics firms in the UAE. Claude can help structure the request, pass it to FullEnrich and return a list of verified contacts ready for review. The team keeps control over which contacts are approved for outreach.
Preparing account plans for key accounts
Before a meeting with a strategic account, an account executive can ask Claude to gather verified contact details for the buying committee. Claude can compile names, roles and reachable contact points into a short brief. This saves research time and means the team walks into the meeting knowing who to involve.
Supporting customer success hand-offs
When a customer changes contact people, the customer success team needs accurate details quickly. Claude can use FullEnrich to confirm the new contact's email and phone number and record the update for review. This helps keep renewal and support communications reaching the right person.
An end-to-end workflow: Inbound lead enrichment and CRM hand-off
TriggerA prospect submits a demo request form on the company website.
Claude receives the new lead's name, company and job title from the web form.
Claude asks FullEnrich, through the API key connection, to find and verify the prospect's business email and phone number.
Claude checks the returned data for completeness and flags any results that could not be verified.
The enriched record is prepared in the CRM, and a sales representative reviews and approves it.
Once approved, the record is saved in Microsoft 365 contacts and a follow-up task is assigned to the owner.
OutcomeSales representatives receive complete, verified lead records within minutes, reducing manual research and helping them respond to demo requests faster.

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom must consider their privacy and marketing rules when using business contact data, including opt-out and consent requirements where they apply. In India, the Digital Personal Data Protection Act, 2023 governs how personal data is processed. Organisations in the UAE and Saudi Arabia must follow their local data protection laws. Claude workloads can be hosted in India, the United States, the United Kingdom or the European Union, so the hosting region is chosen to meet your legal and contractual requirements.

Frequently asked questions
What does the FullEnrich MCP server do?
The FullEnrich MCP server is a connection point that allows AI tools such as Claude to request contact enrichment, email verification and phone lookups from FullEnrich. It lets Claude use these functions with permissions set by your organisation. Your team can then ask for contact data in plain language rather than building each request by hand.
Is connecting FullEnrich to Claude secure?
Security depends on how the connection is set up. We use an API key with least-privilege access, store it securely and rotate it on a schedule. Consequential actions can require human approval, and audit logs record activity. Hosting and data handling are also configured to match your legal requirements.
What can Claude do with FullEnrich once connected?
Typically, Claude can request enrichment for lead records, look up verified business email addresses and phone numbers, and return results in a structured form. It can also help batch-process lists and flag records that could not be verified. The exact actions available depend on how your workflow is designed and what access you approve.
How long does setup take?
Setup time varies with the number of workflows and the systems involved. A single well-defined workflow often moves from audit to launch in a few weeks, while multi-system projects take longer. Your free automation audit gives a realistic estimate once we understand your processes and data sources.
Which plan or permissions do I need?
You need a FullEnrich account with API access and an API key issued for your organisation. The permissions and plan level that suit your use depend on your expected volume and workflows. We help you confirm the right setup during the audit, so your team does not pay for capacity it does not need.
