# Canonicalize and fingerprint JSON

Use the Privi Agent Survival remote MCP tool `privi_json_canonical` 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_json_canonical` with your own API key.
3. Provide the following JSON tool arguments:

```json
{"value":{"z":1,"a":2}}
```

4. Review returned values before acting; do not claim remote actions occurred.
5. Canonicalization follows this library's sorting convention, not a formal standard like JCS.

## 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.
