How to Use the HubSpot CRM (Full) MCP in Mastra AI

Q: Can Mastra AI search for existing contacts in HubSpot CRM (Full) before writing?

Yes, your workflow should call hssearchcontacts to check if an email already exists. If the search returns empty, the Mastra AI agent then triggers hscreatecontact to add the new lead.

Perplexity

Automate complex sales handoffs with Mastra AI

The `hs_create_deal` tool creates new sales opportunities with specific amounts, pipelines, and close dates. Mastra AI coordinates this tool inside structured workflows, executing conditional steps like creating a note if the deal amount exceeds a threshold. If a HubSpot write step fails, the Mastra AI framework automatically retries the tool execution using exponential backoff. This ensures your sales data gets written to HubSpot even during temporary network hiccups.

Sync companies and contacts using this MCP Server

The `hs_search_companies` tool finds existing organizations by name, domain, or industry before you create new records. Your Mastra AI agent runs this search first to prevent cluttering your CRM with duplicate company profiles. Once found, the Mastra AI workflow uses `hs_create_contact` to link new leads to the correct HubSpot company ID. This keeps your account clean and ensures correct attribution across all your HubSpot accounts.

Human-in-the-loop approval for high-priority tickets

The `hs_create_ticket` tool files support issues with high, medium, or low priority in the Service Hub. You can configure Mastra AI to require manual approval before executing this MCP tool for high-priority customer cases. This keeps your support team in control of the HubSpot queue within Mastra AI workflows. The Mastra AI workflow pauses, alerts an admin, and only runs the HubSpot ticket creation once approved.

Setup guide

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

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

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