Knack MCP by usefulapi

Connect Claude, Cursor, or any MCP client to your Knack no-code database — read, create, update and delete records, and inspect objects, fields and schema.

Live endpoint: https://knack.usefulapi.io/mcp · Homepage: https://usefulapi.io/knack

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://knack.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http knack https://knack.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "knack": {
      "url": "https://knack.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Knack credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/knack/

On first connect you'll paste two credentials — your Application ID and REST API Key (Knack Builder → Settings → API & Code). They're sent as the X-Knack-Application-Id and X-Knack-REST-API-Key headers on every request.
