Prospeo MCP with Claude: Faster B2B Lead Research and Contact Verification
The short answer
Claude connects to Prospeo through the Model Context Protocol (MCP), or through Prospeo's direct API. Once connected, Claude can search for people and companies, enrich contact details and verify email addresses. Users make requests in natural language, and access is controlled by the organisation's own API key and permissions.
What is Prospeo?
Prospeo is a B2B prospecting API. It provides person search, company search, contact enrichment and email verification, helping teams find accurate lead data faster. Sales development representatives, account executives, marketing operations staff and customer success teams typically use it to build prospect lists and keep contact records current before outreach campaigns begin.
How Claude connects to Prospeo through MCP
The Model Context Protocol is an open standard that lets Claude securely use other software. Think of it as a universal adapter between Claude and a tool. Through it, Claude can read information from Prospeo and take actions in it, using permissions the organisation sets.
Once connected, Claude can search for people and companies, enrich contact records and check whether email addresses are valid. A sales team member might simply ask for decision makers at a named company in a given city, and Claude carries out the lookup and returns the results in a readable form.
Permissions and approvals keep people in charge. Access is granted with the organisation's own API key and limited to the functions the team needs. Consequential actions, such as adding large batches of contacts to a campaign, can be set to require a person's approval before they proceed.
What you can automate
Building targeted prospect lists
A sales manager asks Claude for finance directors at mid-sized manufacturers in a particular region. Claude searches Prospeo's person and company data, filters the results against the criteria, and presents a clean list. The manager reviews the list before it is used, saving hours of manual searching across several websites.
Enriching existing CRM contacts
A sales operations lead has hundreds of contacts with missing job titles or company details. Claude uses Prospeo's contact enrichment to fill in gaps, flagging records it could not complete. This typically leads to fuller records that account executives can use when planning calls and follow-ups.
Cleaning email lists before a campaign
A marketing team preparing an outbound email sequence asks Claude to verify a large list of addresses. Claude runs Prospeo's email verification and returns a summary of valid, risky and invalid addresses. Teams often use this to reduce bounce rates before sending, which helps protect sender reputation.
Researching companies before outreach
A business development representative needs background on a company before a first call. Claude fetches company data through Prospeo, such as size, industry and location, and summarises it in a short briefing. The representative arrives at the call better prepared without switching between tools.
Supporting customer success account reviews
A customer success manager preparing a quarterly review wants to identify new stakeholders at existing client accounts. Claude searches for relevant contacts at those companies and lists people who may be worth introducing to the wider relationship, with the manager deciding who to approach.
An end-to-end workflow: Trade show lead capture to CRM
TriggerA sales team returns from a trade show with a spreadsheet of about 300 badge scans, many with incomplete details.
Claude reads the spreadsheet and identifies records missing job titles, company names or email addresses.
Claude uses Prospeo to enrich each incomplete record and search for missing contact details.
Claude runs email verification on every address and marks valid, risky and invalid results.
A sales operations person reviews a summary and approves the records to be imported.
Approved, verified contacts are written into the CRM (for example Microsoft Dynamics 365 or Salesforce) with source and date tags.
Account owners receive a task in their calendar to follow up within two working days.
OutcomeTypically, the team moves from a messy spreadsheet to a verified, enriched CRM record set in a fraction of the time manual research would take, with follow-up started while the event is still fresh.

Frequently asked questions
What does the Prospeo MCP server do?
The Prospeo MCP server lets Claude securely access Prospeo's functions for person search, company search, contact enrichment and email verification. It acts as a bridge, so Claude can carry out these lookups when someone asks in plain English. The server uses your API key and only performs the actions your permissions allow.
Is connecting Prospeo to Claude secure?
Security depends on how the connection is set up. Access is granted with your organisation's own API key, limited to the functions each workflow needs. Activity can be logged and consequential actions can require approval. We design and review these controls with you before launch.
What can Claude do with Prospeo once connected?
Typically, Claude can search for people and companies, enrich existing contact records, verify email addresses and retrieve company information. Users make requests in natural language, and Claude returns results that the team can review and use in their own tools.
How long does setup take?
Timing depends on the number of workflows and the systems involved. A single well-defined workflow with one API key connection can often be set up within a few weeks, including testing and team training. More complex, multi-system projects take longer. The free automation audit gives a realistic timeline.
Which plan or permissions do I need?
Generally, you need an active Prospeo account with an API key that has permission for the functions you plan to use. The exact access depends on your Prospeo agreement and your internal permissions. We check this during the audit so there are no surprises at launch.
