Enigmagent MCP

enigmagent-mcp is a local encrypted vault server for MCP-capable clients. It stores secret values with an Argon2id-derived AES-256-GCM key and keeps the vault file encrypted at rest.

People who work with aes 256 gcm, argon2id and secrets and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Enigmagent MCP

Claude Code

claude mcp add agnuxo1-enigmagent-mcp -- npx -y enigmagent-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "agnuxo1-enigmagent-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "enigmagent-mcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key
