What update_tag does on TickTick MCP Service

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

Why update_tag needs a policy

This tool modifies data reversibly by updating tag attributes. It is not a Read operation (it changes state), not Execute (it doesn't run arbitrary code or external operations), not Destructive (the tag itself persists and the change is reversible), and not Financial.

From the tool's definition Tool name 'update_tag' with description stating it updates tag information (更新标签信息); it modifies existing tag data by allowing changes to name and color properties via the 'name' and 'color' parameters.

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

How to control update_tag

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

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

update_tag 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 TickTick MCP Service — 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.
