# Calculate TTL expiration

Use the Privi Agent Survival remote MCP tool `privi_expiry_window` when this workflow is relevant. The server is a stateless calculation service. It does **not** perform external actions or manage the calling agent's credentials.

## Procedure

1. Confirm the input is user-authorized and contains no unnecessary secrets.
2. Connect an MCP-capable agent to `https://privi-ai-21-gateway.onrender.com/mcp` or use `POST /v1/tools/privi_expiry_window` with your own API key.
3. Provide the following JSON tool arguments:

```json
{"start_iso":"2026-11-13T20:00:00Z","ttl_seconds":3600}
```

4. Review returned values before acting; do not claim remote actions occurred.
5. A computed expiry never revokes a credential by itself; enforce expiration server-side.

## Production cautions

All Privi tool executions require a prepaid API key; public discovery does not grant free execution. Stripe and Base checkout remain disabled until verified.
