THE RISK

Low Risk

Why get_task needs a policy

The verb 'Get' combined with 'task details' clearly describes a query operation that retrieves information. No creation, modification, deletion, code execution, or financial operation is implied. This is a straightforward read operation with minimal security risk.

From the tool's definition Tool name 'get_task' and description 'Get task details including result and execution trace' indicate data retrieval with no modification or side effects.

POLICY

How to control get_task

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_task": {}
  }
}

get_task is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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