How to use ToolKnife MCP with Cursor

Give Cursor access to 273+ deterministic tools via MCP. Finance, math, health, developer utilities, all through one config.

Prerequisites

  • Cursor IDE installed
1

Open MCP settings in Cursor

Open Cursor Settings (Cmd+Shift+P > "Cursor Settings" or Cursor > Settings > Cursor Settings). Navigate to the "MCP" section in the left sidebar.
2

Add a new MCP server

Click "Add new MCP server". You can either use the UI to enter the details, or create/edit the `.cursor/mcp.json` file in your project root directly.
.cursor/mcp.json
{
  "mcpServers": {
    "toolknife": {
      "type": "streamable-http",
      "url": "https://toolknife.com/api/mcp"
    }
  }
}
3

Verify the connection

The MCP section in Cursor settings should show "toolknife" as connected with a green status indicator. If it shows red, check your internet connection and try toggling the server off and on.
4

Use it in Composer or Chat

In Cursor's Composer (Cmd+I) or Chat panel, ask something computational: "Calculate compound interest on $10,000 at 7% for 20 years with monthly compounding." Cursor will call the tool and return exact results.
5

Optional: Add an API key

For higher rate limits, add your API key from toolknife.com/dashboard/api-keys.
With API key
{
  "mcpServers": {
    "toolknife": {
      "type": "streamable-http",
      "url": "https://toolknife.com/api/mcp",
      "headers": {
        "x-api-key": "tk_your_api_key_here"
      }
    }
  }
}
