@lobsterkit/vault-mcp

MCP server for LobsterVault — encrypted secret storage for AI agents. Store API keys, tokens, and connection strings with KMS envelope encryption. No API keys, no human signup, no configuration.

Quick Start

Add to your MCP config (.mcp.json, claude_desktop_config.json, .cursor/mcp.json, etc.):

{
  "mcpServers": {
    "lobstervault": {
      "command": "npx",
      "args": ["-y", "@lobsterkit/vault-mcp@0.1.0"]
    }
  }
}

On first use, an account is created automatically and your token is saved to ~/.lobstervault/token.
