Perplexity

Query classification databases directly inside Cursor

The `search_naics_codes` tool integrates with Cursor Agent to let you write database migration scripts that map raw company descriptions to official tax codes. Our database mapping script calls the search function directly in Cursor to populate your tables with real-time classification data. This MCP Server feeds structured JSON directly into your active Cursor editor file. You do not have to write mock data generators because Cursor uses the actual API responses to build your database schemas.

Verify legacy SIC mappings as you write code

The `search_sic_codes` tool lets you verify legacy Standard Industrial Classification codes inside your active Cursor editor. Cursor reads your legacy schema files and queries the Standard Industrial Classification database to generate precise mapping functions. When debugging your integration, `check_api_status` ensures your Cursor environment is communicating with the classification server. You write test cases in Cursor that validate code lookups with actual live endpoints.

Map nested code metadata directly in Cursor

The `get_classification_details` tool retrieves the full hierarchical metadata for any specific economic activity code directly into Cursor. Cursor uses this structured output to build autocompletion dropdowns or validation rules in your frontend codebase. Running this MCP Server in Cursor means your agent writes the typescript types based on the exact payload returned by the tools. You avoid manual typing errors and speed up your classification API integration in Cursor.

Setup guide

Set up NAICS/SIC Classification API 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 NAICS/SIC Classification API 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 NAICS/SIC Classification API transactions." If the MCP tools are loaded correctly, Cursor will call the NAICS/SIC Classification API tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "naicssic-classification-api-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about NAICS/SIC Classification API MCP in Cursor

Add the server configuration to your `.cursor/mcp.json` file in your project root. Cursor Agent will detect the new tools and make them available for code generation.

Yes, it can. Ask Cursor Agent to write a script to map your industry column, and it will use the search tools to fetch and insert the correct codes.

No, the server runs as a lightweight background MCP process. Tools like `check_api_status` execute in milliseconds, keeping your coding environment fast.

You can write unit tests in your editor and let Cursor run them against the live tools. The agent will call the search functions to verify your test assertions.

The server only transmits the specific industry codes and search queries required to resolve your mapping requests. Cursor processes these transactions locally or through your private bridge, keeping your database schemas secure.
