THE RISK

Low Risk

Why get-calendars needs a policy

This tool retrieves and queries calendar metadata without side effects. It fetches existing data (colors, settings, sync status) but does not create, modify, delete, or execute operations. This is a straightforward Read operation with minimal risk—calendar metadata is typically non-sensitive configuration data. Even if an agent calls this repeatedly, no harm occurs.

From the tool's definition Tool name 'get-calendars' and description 'Get all calendars. Returns calendar metadata including colors, settings, and sync status.' indicate pure data retrieval with no modification, creation, or deletion of resources.

POLICY

How to control get-calendars

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 get-calendars:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get-calendars": {}
  }
}

get-calendars 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 Akiflow 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.
