Mastra AI workflow integration

You can now chain lead creation into your complex Mastra AI workflows. Add the `create_hubspot_lead` tool to your agent's toolkit to trigger CRM updates based on logical conditions. Since it supports human-in-the-loop, you can require approval before the tool executes. This ensures only qualified leads hit your CRM database.

Robust lead handling with Mastra AI

The `create_hubspot_lead` tool integrates natively into your agent's decision-making process. If your agent determines a user is a potential client, it calls this tool with the extracted data. This setup allows you to build multi-step flows where lead capture is just one piece of the puzzle. You get granular control over when and how the CRM is updated.

Automated CRM entry for Mastra AI

By using the HubSpot Lead Creator within your agent framework, you remove manual data entry tasks. The agent extracts contact info and passes it to the `create_hubspot_lead` function automatically. It works perfectly with your existing Mastra AI infrastructure. Just register the server and start using the tool in your agent definitions.

Setup guide

Set up HubSpot Lead Creator 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 HubSpot Lead Creator 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: "hubspot-lead-creator-mcp-client",
  servers: {
    "hubspot-lead-creator-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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