How to Use the Happierleads MCP in Mastra AI

Q: How do I register Happierleads in a Mastra AI agent?

Instantiate MCPClient from @mastra/mcp with your Vinkius server URL, then fetch the tools using mcpClient.listTools(). Spread these tools directly into your Mastra agent configuration. The agent can then call happierleadsinfo whenever it needs to identify an anonymous corporate visitor.

Trigger branch workflows with Mastra AI and MCP

The `happierleads_info` tool acts as the primary data trigger inside your Mastra workflow engine. When an anonymous visitor hits a high-value page, the agent queries this tool to resolve the corporate domain and instantly routes the lead based on company size. If the tool identifies an enterprise account, Mastra branches the workflow to ping your sales team on Slack. For smaller companies, the agent automatically queues a personalized email sequence, executing these decisions without manual intervention.

Automatic retries for firmographic lookups

The `happierleads_info` tool integrates with Mastra's built-in retry logic to handle temporary network hiccups or API rate limits. If a lookup fails, the workflow backs off exponentially and tries again, ensuring you never miss a high-intent visitor. You don't have to write custom error-handling code. Mastra manages the execution state of the server tool, keeping your backend clean and your lead data pipeline reliable.

Human-in-the-loop lead verification

The `happierleads_info` tool supports Mastra's `requireToolApproval` setting to prevent accidental outreach to sensitive accounts. Before your agent sends automated messages to a resolved domain, the workflow pauses and waits for a manual thumbs-up from a team member. This safeguard protects your brand reputation and prevents compliance issues. You get the speed of automated deanonymization with the security of human oversight.

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-mcp-client",
  servers: {
    "happierleads-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);

Common questions about Happierleads MCP in Mastra AI

Instantiate `MCPClient` from `@mastra/mcp` with your Vinkius server URL, then fetch the tools using `mcpClient.listTools()`. Spread these tools directly into your Mastra agent configuration. The agent can then call `happierleads_info` whenever it needs to identify an anonymous corporate visitor.

Yes, you can build complex workflows that branch based on the output of `happierleads_info`. For example, your Mastra agent can check the company size returned by the tool and route enterprise leads to one slack channel and mid-market leads to another.

Mastra uses built-in workflow steps that support automatic retries and exponential backoff. If the `happierleads_info` tool hits a rate limit, Mastra pauses the workflow and retries the execution, preserving your API credits and ensuring data consistency.

No, the Mastra MCP client auto-detects whether the connection uses Streamable HTTP or Server-Sent Events. You only need to provide the Vinkius endpoint URL during initialization, and Mastra handles the underlying communication protocol automatically.

The MCP server processes all firmographic lookups over encrypted TLS connections directly to Happierleads. No visitor IP addresses or resolved corporate domains are written to persistent logs, meeting strict compliance requirements for enterprise data handling.
