Build resilient prospecting loops using this MCP Server

`search_leads` acts as the primary data fetcher for your automated outbound workflows. This tool allows your Mastra agents to query targeted industries and extract fresh corporate profiles. Because Mastra handles conditional branching, you can route the output of this search directly into validation steps. If a lead lacks a phone number, the workflow automatically branches to search alternative sources.

Automated email verification with built-in retries

`verify_email` is your insurance policy against high bounce rates and ruined domain reputations. This tool validates the deliverability of every address found during your automated runs. Mastra's workflow engine applies exponential backoff if the verification service experiences temporary network lag. This ensures your bulk runs finish successfully without manual intervention.

Dynamic list building and company enrichment

`create_contact_list` organizes your verified prospects into structured campaigns automatically. This tool lets your agent group leads by industry, size, or custom tags on the fly. Once the list is created, the MCP tool fills in the blanks by fetching detailed firmographic data. Your Mastra workflows can then segment these lists and push them straight to your CRM.

Setup guide

Set up Findymail MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Findymail tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "findymail-mcp-client",
  servers: {
    "findymail-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Findymail Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Findymail tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Findymail transactions"
);
console.log(result.text);

Common questions about Findymail MCP in Mastra AI

Instantiating the client requires the Mastra MCP package. Use the MCPClient class to connect to the Vinkius URL, then spread the returned tools directly into your agent's configuration object.

Yes, you can set requireToolApproval to true on sensitive tools like `find_phone`. This pauses the workflow and sends a notification before spending credits on direct dials.

The framework features a built-in workflow engine that automatically retries failed tool executions. If `find_email` fails due to a temporary network issue, Mastra retries the call using exponential backoff.

Yes, you can chain `enrich_company` and `verify_email` in a Mastra pipeline. The workflow engine processes these in sequence, maintaining clean state at every step.

Your API key is stored as an environment variable and injected securely during tool execution. The MCP Server only handles business emails and phone records, processing them in ephemeral, zero-trust sandboxes.
