List tasks from a task list. Supports filtering by due date range and completion status.
AI agents call list-tasks to retrieve information from Google Tasks without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries task data without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk—the worst case is unauthorized access to read task list contents.
From the tool's definition Tool name 'list-tasks' and description 'List tasks from a task list' indicate a retrieval operation with no modification capability. Filtering parameters (due date range, completion status) are query-only operations.
Attacks that exploit this kind of access
List tasks from a task list. Supports filtering by due date range and completion status. It is categorised as a Read tool in the Google Tasks MCP Server, which means it retrieves data without modifying state.
Register the Google Tasks 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 Google Tasks. 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 Google Tasks MCP server (scottie-will/google-tasks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
