Summary
This gives Claude direct access to your development environment through tools for parsing dotenv files, checking port availability, and inspecting system info. You get operations like env_list_variables to see what's in your .env, env_compare_files to diff against .env.example, port_check to identify what's using port 3000, and system_info for OS and runtime versions. The env_generate_example tool creates sanitized templates by stripping values while preserving structure. Useful when Claude needs to troubleshoot configuration issues, verify dependencies are installed, find an open port for a new service, or detect missing environment variables before deployment.
Keeps your Mac awake while Claude Code, Codex or Cursor works. Lets it sleep when they are done.

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
.envfile and list all variable keys (values masked) - env_detect_missing - Check if required environment variables are present and populated
- env_compare_files - Compare
.envvs.env.exampleto find missing or extra variables - env_find_duplicates - Find duplicate variable keys in a
.envfile
Environment Generator
- env_generate_example - Generate
.env.examplefrom an existing.envfile (strips values, keeps comments, adds placeholders) - env_detect_from_package_json - Detect environment variables referenced in
package.jsonscripts - env_detect_from_docker_compose - Detect environment variables referenced in a
docker-compose.ymlfile
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
