WHAT IT DOES

What store_data does on Agent Jail

AI agents use store_data 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 store_data is rated Medium

The name 'store_data' strongly suggests a write operation (creating or storing data). However, the empty description provides no details about what data is stored, where, or whether it could be destructive. Given the sibling tools context (expense tracking, email, user info), this is likely a general-purpose write operation. Confidence is lowered due to the lack of description.

From the tool's definition Tool name 'store_data' implies writing/storing data; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs store_data 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 store_data, this is the rule to start with:

store_data Rate-limited

store_data 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.
