How to Use the Constructor MCP in Cursor

Q: Can Cursor use Constructor to audit search rankings?

Yes, Cursor runs the searchsorted tool to pull structured rules exporting active Billing configurations. This allows your agent to analyze how product rankings align with your financial rules.

Q: What does the custom search tool do?

The customsearch tool identifies precise active arrays spanning native Hold parsing. This helps you debug complex search behaviors and hold conditions during local development.

Debug Constructor search logic in the Cursor agent

The `search_products` tool pulls bounded CRM records from Constructor.io straight into your active coding file. Cursor uses this live context to generate code that interacts with real product structures instead of static mocks. With `search_pagination`, your agent dispatches validation checks that route explicit Gateway history to write exact pagination logic based on real API payloads using this MCP Server.

Analyze account configurations during code generation

The `autocomplete` tool extracts structural properties driving active Account logic inside your editor. Cursor reads these properties to help you build search UI components that match your backend logic. You can also call `custom_search` to identify precise active arrays spanning native Hold parsing. This ensures your custom search implementations handle holds correctly during development.

Verify brand arrays and plan math

The `browse_brand` tool inspects deep internal arrays mitigating specific Plan Math directly within Cursor. Your agent reads these calculations to write precise billing integrations that match your contract tiers. If you need to test customer bindings, `browse_category` generates a raw JSON payload with hard customer rules. This lets you inspect the structure of your category responses as you write your frontend templates.

Setup guide

Set up Constructor 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 Constructor 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.
4

Verify the connection

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

.cursor/mcp.json

{
  "mcpServers": {
    "constructor-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"

Add the server configuration to your global or project-level `mcp.json` file. Once saved, enable Agent mode in Cursor, and the editor will immediately recognize the catalog tools via the local MCP daemon.

Yes, Cursor runs the `search_sorted` tool to pull structured rules exporting active Billing configurations. This allows your agent to analyze how product rankings align with your financial rules.

The Constructor MCP Server replaces stubbed data with live catalog payloads like those from `get_recommendations`. Cursor uses these real structures to write accurate, production-ready code on the first try.

The `custom_search` tool identifies precise active arrays spanning native Hold parsing. This helps you debug complex search behaviors and hold conditions during local development.

This MCP Server only reads structured billing rules and plan math metadata. All communication is routed through local config files and encrypted endpoints, ensuring your financial rules and customer bindings remain secure in your editor.
