How to Use the Knack MCP in Cursor

Q: How do I configure the Knack MCP server in Cursor?

Create an mcp.json file in your project root directory. Add the server details and switch your chat to Agent mode to enable the tools.

Q: Can Cursor automatically find my Knack application ID?

Yes. The agent runs listaccountapplications to discover the correct application IDs. It binds those IDs to your environment variables for immediate use.

Q: Does this tool support partial record updates?

The updaterecord function accepts partial JSON payloads. You only send the specific fields you want to change, leaving the rest of the database row intact.

Connect Cursor directly to your Knack MCP server. Generate working frontend code using live schemas and real API data inside your editor.

Perplexity

Pull live schemas into Cursor

The `list_object_fields` tool fetches the exact data types and internal keys from your Knack database right into Cursor's context window. Your agent uses `get_object_schema` to understand the table relationships before writing a single line of fetch logic. Writing integration code against outdated documentation causes endless debugging loops. Injecting the live schema directly into your IDE means the AI generates TypeScript interfaces that perfectly match your actual Knack environment.

Seed real data with this MCP Server

The `list_records` tool dumps actual database rows into your editor so Cursor can build UI components using real content. Instead of generating generic placeholder text, the agent writes React components mapped to your live Knack data. When you need specific edge cases, `search_records` isolates exact records using Knack's JSON filter syntax. You get working code that handles the exact data structures your application actually processes in production.

Generate working database mutations

The `create_record` tool proves your insertion logic works before you even commit the code. Cursor writes the API call, formats the JSON payload with the correct `field_x` keys, and executes the write to verify the endpoint accepts it. Updating existing rows follows the exact same pattern. The agent tests partial data payloads via `update_record` to ensure your patch requests function properly. You stop guessing about API requirements and start shipping verified database interactions.

Setup guide

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

.cursor/mcp.json

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

Yes. The agent runs `list_account_applications` to discover the correct application IDs. It binds those IDs to your environment variables for immediate use.

Ask the agent to build a form for a specific table. It will trigger `list_object_fields` to get the internal keys, then write the exact HTML inputs required to submit data.

The `update_record` function accepts partial JSON payloads. You only send the specific fields you want to change, leaving the rest of the database row intact.

Your customer records and application metadata remain strictly within your local V8 Isolate Sandbox. The connection handles authentication via ephemeral tokens, ensuring no persistent access to your database rows after the session ends.
