AI agents call list_tasks to retrieve information from ATMcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or queries task data with optional filtering parameters. It does not create, modify, delete, or execute operations; it only reads and returns information about tasks. This is a standard Read-category operation with minimal risk if misused by an AI agent.
From the tool's definition Tool name is 'list_tasks' and description states it 'List the task board, optionally filtered by status/assignee/goal or since a cursor' — this is a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List the task board, optionally filtered by status/assignee/goal or since a cursor. It is categorised as a Read tool in the ATMcp MCP Server, which means it retrieves data without modifying state.
Register the AT MCP server in PolicyLayer and add a rule for list_tasks: 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 ATMcp. Nothing to install.
list_tasks 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_tasks 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_tasks. 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_tasks is provided by the AT MCP server (midcheck/atmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
