What is the Findymail MCP Server?
Connect your Findymail account to any AI agent and supercharge your sales prospecting and data enrichment workflows through the power of the Model Context Protocol (MCP). Findymail is designed for high-growth sales teams that need accurate, verified contact data without the manual grind of searching through LinkedIn or guessing email patterns.
What you can do
- Precision Email Finding — Instantly retrieve verified B2B emails by providing a person's name and their company domain or name. No more guessing; get data that actually delivers.
- Real-time Email Verification — Protect your sender reputation by verifying any email address before it hits your outreach sequence. Our verification tool checks for deliverability in seconds.
- Direct Phone Discovery — Scale your cold calling efforts by fetching direct phone numbers directly from LinkedIn profiles using our specialized phone finder tool.
- Deep Company Enrichment — Transform a simple domain or LinkedIn URL into a full company profile, including industry data, size, and social identifiers.
- Intellimatch Lead Generation — Use natural language to discover new leads. Simply ask your agent to 'Find SaaS founders in the US' or 'Get me marketing heads in London', and let Findymail do the heavy lifting.
- List & Contact Management — Organically manage your prospecting lists and retrieve specific contact details to keep your CRM updated and your outreach personalized.
- Credit Monitoring — Keep a pulse on your API usage with built-in tools to check your remaining credits and usage summaries directly from your AI conversation.

Frequently asked questions
How does Findymail ensure the accuracy of the found emails?
Findymail uses a proprietary verification engine that checks the deliverability of B2B emails in real-time. By using the 'verify_email' tool, you can double-check any address to ensure your bounce rate stays below 1%.
Can I search for leads using natural language like 'Founders in San Francisco'?
Yes! The 'search_leads' tool uses the Intellimatch engine, allowing you to discover companies and contacts based on conversational queries. It's like having a lead researcher built into your AI agent.
What happens if a phone number or email cannot be found?
If Findymail cannot locate a verified contact, the tool will return a null or empty status. Findymail only charges credits for successful finds, ensuring you only pay for data you can actually use.
