# Danger Zone MCP A Model Context Protocol (MCP) server that allows executing predefined commands with safety checks. ## Features - Execute safe commands from configuration - Execute dangerous commands with native macOS confirmation dialog - Support for pre-authorized dangerous commands (skip confirmation) - JSONC support (JSON with comments) - Multiple configuration file formats supported (.jsonc and .json) - Fallback to global config in `~/.claude/` if project config not found - TypeScript implementation - Works with npx for easy execution ## Installation ```bash npm install -g @koinunopochi/danger-zone-mcp ``` Or use with npx (no installation required): ```bash npx @koinunopochi/danger-zone-mcp ``` ## Configuration Create a configuration file in your project root or home directory: 1. **Project-specific config** (highest priority): - `<project>/.claude/.danger-zone-exec.local.jsonc` (recommended for comments) - `<project>/.claude/.danger-zone-exec.local.json` 2. **Global config** (fallback): - `~/.claude/.danger-zone-exec.jsonc` (recommended for comments) - `~/.claude/.danger-zone-exec.json` ```jsonc { // Safe commands that can be executed without confirmation "commands": [ { "name": "build_project", "description": "Build the project", "command": "npm", "args": ["run", "build"] }, { "name": "check_chrome_mcp", "description": "Check if MCP Chrome profile instances are running", "command": "ps aux | grep -E '(Google Chrome.*mcp-chrome-profile)' | grep -v grep | wc -l" } ], // Dangerous commands that require confirmation "dangerZone": [ { "name": "clean_build", "description": "Clean all build artifacts", "command": "rm -rf dist" // Will show confirmation dialog (default behavior) }, { "name": "kill_chrome_mcp", "description": "Kill all Chrome instances with MCP profile", "command": "pkill -f 'Google Chrome.*mcp-chrome-profile'", "preAuthorized": true // Skip confirmation dialog } ] } ``` ## Usage with Claude Desktop / Claude Code Add to your Claude configuration: ```json { "mcpServers": { "danger-zone": { "command": "npx", "args": ["@koinunopochi/danger-zone-mcp"] } } } ``` Note: When using Claude Code, the `cwd` is automatically set to your current project directory. ## Development ```bash # Install dependencies npm install # Build npm run build # Run in development mode npm run dev ``` ## Configuration Options ### Command Properties - `name`: Tool name (used as `exec_<name>`) - `description`: Description shown in Claude - `command`: Shell command to execute - `args`: Optional array of default arguments ### DangerZone Properties - `name`: Tool name (used as `danger_<name>`) - `description`: Description shown in Claude - `command`: Shell command to execute - `preAuthorized`: Skip confirmation dialog if true (optional, defaults to false) ## Safety Features - Dangerous commands show native macOS confirmation dialog by default - Pre-authorized commands can skip confirmation when explicitly configured - Commands are sandboxed to configured list - Clear separation between safe and dangerous operations
