What list_task_runs does on Todos
AI agents call list_task_runs to retrieve information from Todos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_task_runs is rated Low
This tool queries and retrieves run ledger data without modifying, deleting, or executing anything. It is a pure read operation that returns information about task runs. The optional scoping parameter does not change the fundamental read-only nature of the tool. Blast radius is minimal—misuse would only expose or exfiltrate existing task run data, not modify or delete it.
From the tool's definition Tool name 'list_task_runs' and description 'List local run ledger entries, optionally scoped to a task' indicate query/retrieval operations with no modification or side effects.
Attacks that exploit this kind of access
The rule that runs list_task_runs safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Todos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_task_runs, this is the rule to start with:
list_task_runs is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Todos, apply this rule, and every list_task_runs call is checked against it from then on.
