Automated firmographics in Mastra AI

Link `find_company` to your agents to automate lead qualification. If the agent finds a match, the workflow proceeds to the next step. If the data is missing, use the Mastra framework to retry the lookup or branch to a manual review task. It handles the logic for you.

Person enrichment inside Mastra AI agents

Connect `find_person` to your agent tools to build dynamic contact lists. The agent pulls the email data and updates your records automatically. You can set up exponential backoff for these lookups to keep your API usage steady. It keeps the agent running even if the external service hits a snag.

Risk auditing with Mastra AI workflows

Use `find_risk` within a multi-step agent pipeline to flag bad accounts. The agent checks the risk level and decides whether to block or allow the lead. It turns a manual audit into a background process. Your team only hears about it if the agent flags a high-risk profile.

Setup guide

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

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

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

Common questions about Clearbit (HubSpot) MCP in Mastra AI

Yes, you can define retry policies for any tool call. If the connection drops, Mastra AI will attempt the request again automatically.

Add the server to your agent configuration and spread the tools into the agent's toolset. It auto-detects the transport and is ready to run.

You can force a human-in-the-loop check for sensitive operations. The agent pauses until you approve the tool execution.

Your endpoint token is the only thing needed. Vinkius handles the underlying authentication so you don't expose keys in your code.

No, the server is ephemeral. It fetches the email and company data you need, then clears the memory once the agent finishes the task.
