Env Tools MCP Server

@rog0x/mcp-env-tools

MCP server providing environment and configuration tools for AI agents. Helps with parsing .env files, generating templates, checking ports, inspecting system info, and verifying tool dependencies.

Tools

Environment Parser

• env_list_variables - Parse a .env file and list all variable keys (values masked)
• env_detect_missing - Check if required environment variables are present and populated
• env_compare_files - Compare .env vs .env.example to find missing or extra variables
• env_find_duplicates - Find duplicate variable keys in a .env file

Environment Generator

• env_generate_example - Generate .env.example from an existing .env file (strips values, keeps comments, adds placeholders)
• env_detect_from_package_json - Detect environment variables referenced in package.json scripts
• env_detect_from_docker_compose - Detect environment variables referenced in a docker-compose.yml file

Port Checker

• port_check - Check if a specific port is in use and identify the process
• port_find_available - Find available ports within a given range
• port_list_processes - List processes using specific ports

System Info

• system_info - OS, CPU, memory, disk, Node/npm/Python/Git/Docker versions

Dependency Checker

• deps_check_tools - Check if specified tools are installed and get their versions
• deps_check_versions - Verify installed tools meet minimum version requirements
• deps_verify_path - Analyze the system PATH for common tool directories
