Build automated prospecting workflows in Mastra AI

Stop manually checking who visited your site. This HappierLeads MCP Server lets Mastra AI trigger a workflow that runs `list_visitors` every morning to find new corporate traffic. If a new company is found, the workflow uses `list_qualified_leads` to see if they fit your ideal customer profile. The engine handles retries automatically if the API hits a temporary rate limit.

Route leads using conditional branching

Set up conditional steps based on visitor behavior. Use `list_page_views` to check if the company visited your pricing page or just read a blog post. If they viewed pricing, Mastra AI branches to call `get_lead` to pull decision-maker contact details. Otherwise, it logs the session via `get_session` and waits.

Monitor team notifications autonomously

Keep your sales team in the loop without building complex webhooks. The MCP integration allows the Mastra engine to poll `list_notifications` to detect high-value target accounts on your site. When a notification matches, it triggers an alert step to your Slack. You don't have to write any boilerplate glue code to handle the API response parsing.

Setup guide

Set up HappierLeads 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 HappierLeads 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: "happierleads-alternative-mcp-client",
  servers: {
    "happierleads-alternative-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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