Cmdxray MCP Server

Offline MCP server: explains shell commands token-by-token and flags destructive ones for AI agents. This MCP entry surfaces a curated ranking/list from the project README rather than a classic multi-tool integration surface. It runs locally over stdio via the published package.

People who work with bash, command line and developer tools and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Cmdxray

Claude Code

claude mcp add aurelio-nakamura-cmdxray -- npx -y cmdxray

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "aurelio-nakamura-cmdxray": {
      "command": "npx",
      "args": [
        "-y",
        "cmdxray"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
