Why edit-time-slot needs a policy

This tool modifies calendar time slot entries, which is a reversible write operation. While it affects scheduling data that could impact task management and calendar organization, it does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or retrieve without modification (Read).

From the tool's definition Tool name 'edit-time-slot' and description 'Edit a time slot' indicate modification of existing calendar/schedule data. The verb 'edit' is a write operation that updates data reversibly without deletion or irreversible effects.

POLICY

How to control edit-time-slot

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "edit-time-slot": {
      "limits": [
        {
          "counter": "edit-time-slot_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

edit-time-slot 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
