How to Use the 123FormBuilder MCP in Cursor

Q: Can my Cursor agent create new 123FormBuilder forms for testing?

Yes, the agent can use createnewform to set up a fresh workspace for your tests. It can then call updateforminfo to name the form and prepare it for your code integration. This makes it easy to spin up test environments on the fly.

Q: Can Cursor pull a list of active 123FormBuilder forms?

The agent uses listactiveforms to retrieve all the active forms in your account. You can then ask it to find a specific form by name or ID to inspect its fields. This saves you from searching through the web interface when you need a quick reference.

Generate code against live form schemas and test submissions directly inside Cursor.

Generate code using live form schemas

You ask the Cursor agent to write a frontend component or a backend handler that integrates with your forms. The agent inspects the actual structure of your form with `list_form_fields` and writes accurate, typed code that matches your live fields exactly. You stop writing code based on outdated documentation or guessing field IDs. Your generated code works on the first run because it uses the exact schema pulled directly from your active account.

Test 123FormBuilder webhooks directly in your editor

You write a new webhook endpoint and need to test how it handles actual incoming payloads. The agent pulls your current webhook configurations using `list_form_webhooks` and fetches mock payloads with `get_entry_details` to simulate real-world requests. You avoid setting up complex local tunneling tools or manually triggering form submissions in a browser. You test and refine your API endpoints entirely within your development environment.

Clean up test forms and data while coding

You spin up temporary forms to test your application's submission pipeline and need to wipe them out when done. The agent runs `remove_form` and `remove_entry` to clean up your workspace directly from the chat panel. You prevent your production account from getting cluttered with half-finished test forms. Your workspace remains clean without you ever leaving your code editor.

Setup guide

Set up 123FormBuilder 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 123FormBuilder 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.
