compare_env_filesCompare dotenv files and report which keys are missing from which file, and which are extra relative to a template. Takes file contents directly. Only key NAMES are returned \u2014 never values \u2014 because a dotenv file is where credentials live and the answer does not need them. In "auto" mode the reference is the union of all keys, so nothing can be extra; "template" mode compares every file

EnvSync-LE: Zero Hassle .env Sync Spot missing keys across your .env files before they bite Automatic checks, a status bar counter, and a plain markdown report

What it does
EnvSync-LE compares the variable names across the .env files in your workspace and tells you which files are missing which keys. It never reads or compares values, and it never modifies your files. Works in VS Code and in VS Code–based editors like Cursor and VSCodium (installable from Open VSX).
- Automatic checks — a debounced sync check runs whenever a watched .env file changes
- Status bar counter — the current issue count, one click away from the full report
- Markdown report — Show Details (Ctrl+Alt+S / Cmd+Alt+S) lists every missing key per file
- Three comparison modes — auto (union of all keys), manual (only the files you list), template (validate everything against one reference file; also reports keys a file has that the template lacks)
- Ignore list — temporarily exclude files (e.g. .env.example) from checking
Install
Use it from an AI agent
The same engine runs as an MCP server, so an agent can call it directly instead of you running a command.
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
Install directly
Runs npx -y envsync-le-mcp on your machine. Read the scan report first; the gateway never runs local packages.
