Create a new task in Google Tasks

How to control create ↓

AI agents use create to create or update resources in Google Tasks MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Tasks MCP Server environment.

Medium Risk

Creating tasks is a Write operation because it adds new data to the system and the action is reversible (tasks can be updated or deleted). While the server also supports deletion (Destructive), this specific tool only creates data, making it Write category. Severity is low because task creation has minimal blast radius—accidental task creation causes minor clutter but no data loss or critical impact.

From the tool's definition Tool creates a new task in Google Tasks, which is a reversible data modification operation. The description explicitly states 'Create a new task' and the server integrates with Google Tasks to allow 'creating' among other operations.

Documented attack patterns abuse exactly the kind of access create gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and Google Tasks MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create": {
      "limits": [
        {
          "counter": "create_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Google Tasks MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the create tool do? +

Create a new task in Google Tasks. It is categorised as a Write tool in the Google Tasks MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create? +

Register the Google Tasks MCP Server MCP server in PolicyLayer and add a rule for create: 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 MCP Server. Nothing to install.

What risk level is create? +

create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create? +

Yes. Add a rate_limit block to the create 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.

How do I block create completely? +

Set action: deny in the PolicyLayer policy for create. 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.

What MCP server provides create? +

create is provided by the Google Tasks MCP Server MCP server (zcaceres/gtasks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Google Tasks MCP Server tool call.
