Koskamo

Env Contract MCP

A local Model Context Protocol server that inspects environment configuration drift by comparing variable names in .env.example and dotenv files against references in source code. It reports declared, referenced, missing, and unused names without exposing actual environment values, ensuring safety by reading only local project files.
