AI agents call tasks_listTaskLists to retrieve information from Google MCP Remote without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates task lists without creating, modifying, deleting, or executing any actions. It is a straightforward query operation with minimal blast radius if misused by an AI agent—at worst, it exposes metadata about task list organization but cannot modify or delete data.
From the tool's definition Tool name 'tasks_listTaskLists' and description 'List all task lists' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access tasks_listTaskLists gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Google MCP Remote, and nothing reaches the server without passing your rules. This is the rule we recommend for tasks_listTaskLists:
{
"version": "1",
"default": "deny",
"tools": {
"tasks_listTaskLists": {}
}
}tasks_listTaskLists is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all task lists. It is categorised as a Read tool in the Google MCP Remote MCP Server, which means it retrieves data without modifying state.
Register the Google MCP Remote MCP server in PolicyLayer and add a rule for tasks_listTaskLists: 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 MCP Remote. Nothing to install.
tasks_listTaskLists 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 tasks_listTaskLists 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 tasks_listTaskLists. 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.
tasks_listTaskLists is provided by the Google MCP Remote MCP server (vakharwalad23/google-mcp-remote). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Google MCP Remote, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
