AI agents call task_list to retrieve information from AgentOS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays task information for a session. It has no side effects, does not modify data, and merely provides visibility into existing task state. The optional status filter is a read-time parameter that narrows query results. This is a straightforward Read category tool with low severity due to its passive nature and limited blast radius.
From the tool's definition Tool name 'task_list' and description 'List all tasks for a session with optional status filter' indicate a retrieval operation that queries task data without modifying, deleting, or executing anything.
Attacks that exploit this kind of access
List all tasks for a session with optional status filter. It is categorised as a Read tool in the AgentOS MCP Server, which means it retrieves data without modifying state.
Register the AgentOS MCP server in PolicyLayer and add a rule for task_list: 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 AgentOS. Nothing to install.
task_list 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 task_list 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 task_list. 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.
task_list is provided by the AgentOS MCP server (netflypsb/agentos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
