Cursor MCP Setup

This guide shows how to connect Cursor to cvss-calculator-mcp for CVSS 2.0, 3.0, 3.1, and 4.0 Base Score calculations.

Option 1: Local MCP (stdio) - Recommended

Local stdio executes on your workstation with zero rate limits.

Step 1: Install the Binary (Linux / macOS)

Terminal window
curl -fsSL https://get.cvss.my.id/install.sh | bash

Step 2: Add to .cursor/mcp.json

Create or edit .cursor/mcp.json in your project root (or ~/.cursor/mcp.json for global configuration):

{
  "mcpServers": {
    "cvss-calculator": {
      "command": "cvss-calculator-mcp",
      "args": []
    }
  }
}

Option 2: Remote MCP (Streamable HTTP)

Connect to https://cvss.my.id/mcp over Streamable HTTP without installing a local binary.

Rate limit: 5 requests per minute per IP. For higher usage, run Local MCP (stdio).

Add the remote server to .cursor/mcp.json or ~/.cursor/mcp.json:

{
  "mcpServers": {
    "cvss-calculator": {
      "url": "https://cvss.my.id/mcp"
    }
  }
}

Verify the Connection

  1. Open Cursor Settings > MCP and verify that cvss-calculator shows a green active indicator and lists the calculate_cvss tool.
  2. In Cursor Composer / Agent chat, ask:
Use calculate_cvss to score CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Expected Base Score result: 9.3 (CRITICAL).

Troubleshooting

  • Red status indicator in Cursor Settings > MCP: Cursor GUI applications on macOS/Linux often do not load ~/.bashrc or ~/.zshrc paths. Run which cvss-calculator-mcp in your terminal and set "command" to the full path (e.g. "/usr/local/bin/cvss-calculator-mcp").
  • Rate limit (HTTP 429) on Remote MCP: The public endpoint allows 5 requests per minute per IP. Switch to Option 1 (Local stdio).
