WHAT IT DOES

What list_available_documents does on Cowork Bench

AI agents call list_available_documents to retrieve information from Cowork Bench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_available_documents is rated Low

Even though list_available_documents only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_available_documents safely

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

list_available_documents Allowed

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

  "tools": {

  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Cowork Bench, apply this rule, and every list_available_documents call is checked against it from then on.
