What serac_retrieve does on Serac
AI agents call serac_retrieve to retrieve information from Serac without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why serac_retrieve is rated Low
This tool retrieves pre-existing encrypted data without side effects. It queries/fetches stored information from the user's namespace. The encryption and zero-knowledge architecture suggests the data is isolated per user. No reversible or irreversible modifications, no code execution, and no financial transactions occur. Classification as Read with low severity is appropriate.
From the tool's definition Tool description states 'Retrieve encrypted data from your namespace by key' - retrieve is a read operation with no modification or deletion of data.

The rule that runs serac_retrieve safely

serac_retrieve is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
