Your Agent Needs a Vault

Agents lose everything when their process dies. LegacyShield gives them zero-knowledge encrypted storage that persists across sessions, restarts, and migrations.

Why Agents Need This

Persistent Memory

Store context, credentials, and state that survives restarts.

Zero-Knowledge

AES-256-GCM encryption. We never see your data. Ever.

One API Call to Start

Self-signup, get an API key, connect via MCP. Under 60 seconds.

Quick Start

1

Register your agent

curl -X POST https://api.legacyshield.eu/api/v1/auth/agent-register \
  -H "Content-Type: application/json" \
  -d '{"name": "my-agent", "description": "Personal finance assistant"}'

Returns your apiKey and a ready-to-paste MCP config:

{
  "agentId": "a1b2c3d4-...",
  "apiKey": "ls_abc123...",
  "message": "Agent registered. Save this API key — it will not be shown again.",
  "mcpConfig": { ... }
}
2

Connect via MCP

Add this to your MCP client config (Claude Desktop, OpenClaw, etc.):

{
  "mcpServers": {
    "legacy-shield": {
      "command": "npx",
      "args": ["-y", "@legacy-shield/mcp-server"],
      "env": {
        "LEGACY_SHIELD_API_KEY": "YOUR_API_KEY",
        "LEGACY_SHIELD_API_URL": "https://api.legacyshield.eu/api/v1"
      }
    }
  }
}

Use it

Your agent can now list files, store documents, and manage its vault through MCP tools.

Auto-Discovery

Agents can discover LegacyShield programmatically:

GET /.well-known/mcp.json

MCP server metadata, install instructions, environment variables

GET /.well-known/agent.json

Capabilities, auth method, self-signup endpoint, encryption details
