Common questions

Is EnvSync-LE safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 16 days ago, and the latest version (2.5.0) reached the registry 19 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

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

Useful? A star or rating is how other developers find it —

★ GitHub ·

★ Open VSX ·

★ Marketplace

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 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

Where	What you get	Install
VS Code	The same comparison, live, in your editor	Marketplace
Cursor, VSCodium, Windsurf	The same extension	Open VSX
A terminal or a CI step	The same run over a whole tree, with exit codes	`npx envsync-le` · npm or `cargo install envsync-le` · crates.io
Any MCP agent, via Node	`compare_env_files` over stdio	`npx envsync-le-mcp` · npm

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.

Editor	How
VS Code 1.101+	Nothing to install — the extension registers `compare_env_files` with agent mode
Claude Code	`claude mcp add envsync-le -- npx -y envsync-le-mcp`
Cursor, Windsurf, anything else	point it at `npx envsync-le-mcp`

compare_env_files(files[], mode?, templatePath?, caseSensitive?, maxResults?)

Takes file contents directly and reports which keys are missing from which file. Only key names are returned, never values — a dotenv file is where credentials live and the answer does not need them.

The server takes content and returns data — it reads no files and makes no network requests of its own. Published as envsync-le-mcp on npm and as io.github.nolindnaidoo/envsync-le in the MCP registry.

Configuring it by hand — any host with an MCP config file

Most hosts read a JSON config. Add one entry:

"mcpServers": { "envsync-le": { "command": "npx", "args": ["-y", "envsync-le-mcp"] } } }

-y skips the install prompt on first run. Pin a version if you would rather not track releases — envsync-le-mcp@2.3.0.

Prefer not to go through npx on every launch? Install it once and point at the binary instead:

npm install -g envsync-le-mcp

"mcpServers": { "envsync-le": { "command": "envsync-le-mcp" } } }

It speaks MCP over stdio and needs no environment variables, no API key and no configuration of its own. To check it before wiring it into anything:

echo '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' | npx -y envsync-le-mcp

That prints the tool list and exits — if you see compare_env_files, the server works.

File classification

Filename	Type
`.env`	base
`.env.local`, `.env.*.local`	local override
`.env.example`, `.env.template`	template
`.env.production`, `.env.prod`	production
`.env.development`, `.env.dev`	development
`.env.test`	test
`anything.env`, unknown segments	base

Classification is segment-based on the basename — app.device.env is not "development", and Windows paths classify correctly.

The CLI

The same comparison runs from a terminal or a CI step: a Rust CLI in crate/, sharing one corpus with the extension — crate/fixtures/ — so the two can never read a dotenv file differently. Install it from npm with npm install -g envsync-le (or run it with npx envsync-le) or from crates.io with cargo install envsync-le. Both install the same command and are held to the same output byte for byte.

envsync-le .                            # have these environments drifted? JSON on stdout when piped

envsync-le --template .env.example . # will this deploy break? envsync-le mcp # the same comparison over MCP on stdio

Install it from npm (envsync-le) or from crates.io (envsync-le). Both install the same envsync-le command.

npm install -g envsync-le   # or run it once: npx envsync-le

cargo install envsync-le

.env: missing STRIPE_KEY, SENTRY_DSN (in .env.example) .env.production: missing SENTRY_DSN (in .env.example) out of sync — 2 files with mismatches across 3 files

The exit code is the product — 0 in sync, 1 out of sync, 2 malformed question. Finding no dotenv files at all is 0: there is nothing to be out of sync with. Unlike the extractors in this family there is no list to pipe onward; the number is the answer.

It never reads a value. Only key names are parsed, compared or reported, and three separate checks enforce that rather than a promise.

Commands

Command	Description
`EnvSync-LE: Show Details`	Run a sync check and open the markdown report
`EnvSync-LE: Compare Files`	Compare the key sets of two or more selected `.env` files
`EnvSync-LE: Set Template`	Mark a `.env` file as the reference template
`EnvSync-LE: Clear Template`	Return to automatic comparison
`EnvSync-LE: Ignore File`	Exclude a `.env` file from sync checking
`EnvSync-LE: Unignore File`	Re-include a previously ignored file
`EnvSync-LE: Clear Ignored Files`	Empty the ignore list
`EnvSync-LE: Open Settings`	Open VS Code settings filtered to EnvSync-LE
`EnvSync-LE: Help & Troubleshooting`	Built-in documentation

No command is bound to a key by default. Give any of them one under Keyboard Shortcuts in the editor.

Settings

Setting	Default	Description
`envsync-le.enabled`	`true`	Master switch for sync checking
`envsync-le.watchPatterns`	`[".env*"]`	Glob patterns for files to watch and compare
`envsync-le.excludePatterns`	`[]`	Glob patterns to exclude; patterns without `/` match the basename (so `.env.*.local` excludes nested files too)
`envsync-le.notificationLevel`	`important`	`all` = missing + extra keys, `important` = missing keys + errors, `silent` = nothing
`envsync-le.statusBar.enabled`	`true`	Show the status bar item (applies immediately)
`envsync-le.debounceMs`	`1000`	Delay between a file change and the sync check
`envsync-le.caseSensitive`	`true`	Treat `DB_URL` and `db_url` as different keys
`envsync-le.comparisonMode`	`auto`	`auto`, `manual`, or `template`
`envsync-le.compareOnlyFiles`	`[]`	In manual mode, only compare these files (workspace-relative)
`envsync-le.templateFile`	—	The reference file for template mode (set via `Set Template`)
`envsync-le.temporaryIgnore`	`[]`	Files currently ignored (managed by the ignore commands)
`envsync-le.telemetryEnabled`	`false`	Local-only event log (see Privacy)

Parsing notes

Keys must match A-Za-z_*, so dotted names such as spring.datasource.url count; anything else left of = is reported as a parse error for that line (the rest of the file still counts).
export KEY=value is accepted; duplicate keys count once.
Values quoted with ", ', or ` may span multiple lines; an unterminated quote is reported as an error.
In auto mode the reference is the union of all keys, so "extra keys" only exist in template mode.

Languages

Twelve languages besides English:

German · Spanish · French · Indonesian · Italian · Japanese · Korean · Portuguese (Brazil) · Russian · Ukrainian · Vietnamese · Chinese (Simplified)

Both halves are covered — the manifest (command titles, setting names and descriptions) and everything shown while the extension runs (notifications, the status bar, quick-picks and prompts, and the headings of the report). The help page is written in English. The extension follows VS Code's display language, so it matches whatever the editor is already set to; no setting of its own.

Privacy & security

No network access. The extension never sends data anywhere. The telemetryEnabled setting only writes events to a local Output Channel you can inspect (envsync-le).
Values are never read, displayed, or logged — only key names are compared.
The MCP server returns key names, never values. A dotenv file is where credentials li
