AI agents call list_policy_packs to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves information about policy pack configurations. It has no side effects, does not execute code, does not modify data, and does not delete anything. The blast radius of misuse is minimal—an agent could only learn about existing policies, not change them or trigger external operations.
From the tool's definition Tool name 'list_policy_packs' and description 'List locally configured policy packs for task done gates' indicates a retrieval operation that queries existing configuration data without modifying or executing anything.
Attacks that exploit this kind of access
List locally configured policy packs for task done gates. It is categorised as a Read tool in the Todos MCP Server, which means it retrieves data without modifying state.
Register the Todos MCP server in PolicyLayer and add a rule for list_policy_packs: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Todos. Nothing to install.
list_policy_packs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_policy_packs rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_policy_packs. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_policy_packs is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
