MCP Overview

cvss-calculator-mcp is a fast, lightweight, open-source Model Context Protocol (MCP) server written in Go (alfa-reza/cvss-calculator-mcp). It enables AI coding agents and security tools to validate CVSS vectors and compute Base Scores across CVSS v4.0, v3.1, v3.0, and v2.0.

[!IMPORTANT] Scope Comparison: Base-Only MCP vs Full Browser Calculator The Go MCP server (cvss-calculator-mcp) computes Base Scores only via the calculate_cvss tool. When you need Threat, Temporal, Environmental, or Supplemental metric group scoring, use the Full Browser Calculator.

Two Ways to Connect

Install the standalone single binary onto your workstation and let your AI client launch cvss-calculator-mcp directly over standard input/output (stdio).

Terminal window
curl -fsSL https://get.cvss.my.id/install.sh | bash
  • Supported OS: Linux and macOS (amd64 and arm64), or any platform via go install.
  • Transport: stdio
  • Rate limit: None (100% local execution, works offline).
  • Guide: Local MCP Setup (stdio)

2. Remote MCP (HTTP) - Free Public Endpoint

Connect any MCP client that supports Streamable HTTP directly to the hosted endpoint without installing a local binary:

https://cvss.my.id/mcp
  • Transport: Streamable HTTP
  • Rate limit: 5 requests per minute per IP. For higher usage, run Local MCP (stdio).
  • Note: The endpoint https://cvss.my.id/mcp is a protocol endpoint for MCP clients, not a human HTML page. For the human overview page, visit MCP Tools Overview.
