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.

Why CrewAI?
When paired with CrewAI, Findymail becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Findymail tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

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.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
