01 · Install Envault

before you install - you'll need

Set ENVAULT_CLI_URL, NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, ENCRYPTION_KEY, SUPABASE_SERVICE_ROLE_KEY, UPSTASH_REDIS_REST_URL, UPSTASH_REDIS_REST_TOKEN, NEXT_PUBLIC_API_SIGNATURE_SALT, VERCEL_CLIENT_ID, VERCEL_CLIENT_SECRET, VERCEL_REDIRECT_URI, VERCEL_WEBHOOK_SECRET before connecting.

Claude Code

claude mcp add dinanathdash-envault -- npx -y @dinanathdash/envault-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "dinanathdash-envault": {
      "command": "npx",
      "args": [
        "-y",
        "@dinanathdash/envault-mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

06 · Envault FAQ

What is Envault?

Is Envault still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-02. We re-verify nightly.

How do I install Envault?

Run `npx -y @dinanathdash/envault-mcp-server`. The README documents 12 environment variables (ENVAULT_CLI_URL, NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY…) to set first. Set ENVAULT_CLI_URL, NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, ENCRYPTION_KEY, SUPABASE_SERVICE_ROLE_KEY, UPSTASH_REDIS_REST_URL, UPSTASH_REDIS_REST_TOKEN, NEXT_PUBLIC_API_SIGNATURE_SALT, VERCEL_CLIENT_ID, VERCEL_CLIENT_SECRET, VERCEL_REDIRECT_URI, VERCEL_WEBHOOK_SECRET before connecting. You can also paste the ready-made client config above.

Does Envault run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
