Live HubSpot MCP Server in Cursor

The `create_hubspot_lead` tool fires directly from your IDE when Agent mode is active. You can write a script that processes user signups, and Cursor can test the logic by actually pushing a test contact into your CRM. It expects an email address and accepts optional names, phone numbers, and company details. Developers waste hours mocking up API payloads. This setup lets your AI client hit the real endpoint while you code. You see exactly how the HubSpot API responds without ever leaving your workspace or writing a temporary curl script.

Instant API Payload Testing

Triggering `create_hubspot_lead` proves your data mapping works before you push to production. Cursor reads your current file, figures out what contact variables you are working with, and sends them through the MCP protocol. The record hits HubSpot instantly. That means no more guessing if your custom form logic matches the CRM schema. You get immediate validation. If the request fails, the agent reads the error and helps you rewrite the function on the spot.

Focused Development Workflow

Executing `create_hubspot_lead` is the only action this server handles. We stripped out everything else so the AI does not get confused trying to search or update existing database entries. It writes a new lead, period. This single-purpose design keeps the context window clean. Cursor focuses entirely on writing your application code, while the MCP handles the grunt work of authenticating and formatting the outbound POST request.

Setup guide

Set up HubSpot Lead Creator MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the HubSpot Lead Creator MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.

Ask Cursor something like "List my recent HubSpot Lead Creator transactions." If the MCP tools are loaded correctly, Cursor will call the HubSpot Lead Creator tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about HubSpot Lead Creator MCP in Cursor

Create an MCP configuration file in your project root or your global directory. Add the server details under the mcpServers array. Turn on Agent mode in the chat panel to start testing.

No, the server lacks read permissions. It exposes exactly one write operation. You can push new leads to the database, but you cannot pull records back into your editor.

Because you stay in your editor. The AI writes the code, tests the payload against the real API, and fixes any errors without you switching windows. It merges writing and testing into one step.

It might, depending on your CRM configuration. If you have active workflows that trigger on new contact creation, this tool will set them off. Use a developer sandbox account for testing.

The MCP architecture isolates your execution environment. When you pass an email, firstname, lastname, phone, or company, Cursor sends only those specific variables to the HubSpot endpoint. Your codebase is not uploaded to the CRM.
