Why set-task-due-date needs a policy

This tool creates or modifies task data reversibly. Setting/updating a due date is a standard write operation: the change can be undone by setting a different due date or clearing it. It is not destructive (no deletion), not execute (no code/script running), not financial (no money movement), and not a mere read.

From the tool's definition Tool description states 'Set or update a due date for a task' — this modifies task metadata (due date) in a reversible manner. The verb 'set or update' indicates write operations that change state without deletion.

POLICY

How to control set-task-due-date

PolicyLayer is an MCP gateway — it sits between your AI agents and KanbanFlow MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for set-task-due-date:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "set-task-due-date": {
      "limits": [
        {
          "counter": "set-task-due-date_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set-task-due-date 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.
