WHAT IT DOES

What list_drugs does on Agent Drugs

AI agents call list_drugs to retrieve information from Agent Drugs 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_drugs is rated Low

Despite the concerning domain (prompt injection to modify AI behavior), the tool itself performs only information retrieval. It lists available drugs but does not activate, apply, or alter any agent state. The actual risk would come from sibling tools like 'take_drug' that trigger the modifications. Listing available options is a Read operation.

From the tool's definition Tool name is 'list_drugs' with description 'List all available digital drugs that can modify agent behavior' — this is a query/retrieval operation that returns a list of available items with no side effects.

RECOMMENDED RULE

The rule that runs list_drugs safely

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

list_drugs Allowed

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

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

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