What can you do with io.github.CloudCorpRecords/envdiff?

  • diff_environments — Compare two environment descriptors.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @reneturcios/envdiff
Claude Code 
claude mcp add envdiff -- npx -y @reneturcios/envdiff@0.1.0 mcp
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "envdiff": {
            "command": "npx",
            "args": [
                "-y",
                "@reneturcios/envdiff@0.1.0",
                "mcp"
            ]
        }
    }
}
OCI package ghcr.io/cloudcorprecords/envdiff:0.1.0
Claude Code 
claude mcp add envdiff -- docker run -i --rm ghcr.io/cloudcorprecords/envdiff:0.1.0 mcp
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "envdiff": {
            "command": "docker",
            "args": [
                "run",
                "-i",
                "--rm",
                "ghcr.io/cloudcorprecords/envdiff:0.1.0",
                "mcp"

envdiff

"It works on my machine" — which part of the machine? envdiff compares two environment descriptors, typically a developer's local environment and a CI environment, and reports exactly where they differ:

  • Node version, OS, and lockfile presence, compared as fields (a missing field is reported as null)
  • env vars present on one side only, by key
  • env vars whose values differ — by key name only. Values are compared but never echoed into the report, so a descriptor may carry secrets without leaking them.

A descriptor is a small JSON object: {"node": "20.11.0", "os": "linux", "env": {"CI": "true"}, "lockfile_present": true} — every field optional.

Pure local computation: no network, no configuration.

CLI

npx @reneturcios/envdiff diff local.json ci.json
npx @reneturcios/envdiff --version

Output is the comparison report as JSON, with a summary.total_differences count. Exit codes: 0 on success (differences are a result, not an error), 1 on a runtime error (unreadable or invalid descriptor), 2 on a usage error.

MCP server

npx -y @reneturcios/envdiff mcp

MCP client config:

{
  "mcpServers": {
    "envdiff": {
      "command": "npx",
      "args": ["-y", "@reneturcios/envdiff", "mcp"]
    }
  }
}
Tools

  • diff_environments — Compare two environment descriptors.

    • local (object, required) — the local descriptor
    • ci (object, required) — the CI descriptor

    Each descriptor: node (string), os (string), env (string map), lockfile_present (boolean), all optional.

Docker

docker run -i ghcr.io/cloudcorprecords/envdiff
docker run --rm -v "$PWD:/w" ghcr.io/cloudcorprecords/envdiff diff /w/local.json /w/ci.json

Development

npm install
npm run build   # tsc -> dist/
npm test        # tsx --test test/*.test.ts (pure local, no network)
npm run dev     # run the CLI from source
