WHAT IT DOES

What save does on Agent Jail

AI agents use save to create or update resources in Agent Jail, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Agent Jail environment.

RISK

Why save is rated Medium

The name 'save' suggests writing or persisting data, placing it in the Write category. Without a description, confidence is reduced but the name itself indicates a modification operation. Severity is medium because the blast radius depends on what data is being saved and whether it can be recovered; without specifics, a moderate risk level is appropriate.

From the tool's definition Tool name is 'save', which conventionally creates or modifies data. No description provided to clarify scope or reversibility.

RECOMMENDED RULE

The rule that runs save safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Agent Jail, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For save, this is the rule to start with:

save Rate-limited

save stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
