AI agents call async_tool as a supporting operation in Agent Jail workflows.

RISK

Why async_tool is rated Low

With no description and only a generic name ('async_tool'), there is insufficient information to determine what this tool does. The name alone only suggests it operates asynchronously, but provides no clue about its category or potential impact. Defaulting to 'Other' with very low confidence.

From the tool's definition Tool name is 'async_tool' with an empty description. No information about what the tool does is provided.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

async_tool Rate-limited

async_tool gets a rate cap, and everything else on the server is denied unless you say otherwise.
