JetBrains MCP Setup

These instructions configure JetBrains AI Assistant as an MCP client. They are separate from the MCP server built into JetBrains IDEs.

Install the binary on Linux or macOS:

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

Open Settings → Tools → AI Assistant → Model Context Protocol (MCP), add a server, select STDIO, and provide:

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

Remote MCP (Streamable HTTP)

Add a server using HTTP and provide:

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

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

Verify

Check the server status in the MCP settings. In AI Chat, ask the agent to use calculate_cvss for CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N; the expected Base Score is 5.4 (Medium). Agent availability may depend on your IDE and configuration.

Troubleshooting

  • If STDIO fails to start, use the absolute path from which cvss-calculator-mcp and check the server status.
  • If adding servers is unavailable, check whether your organization manages MCP settings centrally.
