AI agents call google_tasks_list_tasks to retrieve information from Google MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves task data without creating, modifying, deleting, or executing any operations. It is a straightforward read operation analogous to 'list' or 'get' operations, posing minimal security risk even if misused by an AI agent.
From the tool's definition Tool name 'google_tasks_list_tasks' and description 'List tasks from a task list' indicate a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access google_tasks_list_tasks gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Google MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for google_tasks_list_tasks:
{
"version": "1",
"default": "deny",
"tools": {
"google_tasks_list_tasks": {}
}
}google_tasks_list_tasks 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 tasks from a task list. It is categorised as a Read tool in the Google MCP MCP Server, which means it retrieves data without modifying state.
Register the Google MCP server in PolicyLayer and add a rule for google_tasks_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 MCP. Nothing to install.
google_tasks_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 google_tasks_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 google_tasks_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.
google_tasks_list_tasks is provided by the Google MCP server (vakharwalad23/google-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Google MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
