从任务中提取关键词 (来自API) Args: limit: 返回的关键词数量 (默认20) force_refresh: 是否强制刷新缓存数据 (默认为 False) Returns: 关键词频率字典
AI agents call extract_task_keywords to retrieve information from TickTick MCP Service without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads task data and performs keyword extraction/analysis, returning a frequency dictionary. It has no side effects, does not modify or delete any data, and does not execute arbitrary code or trigger external operations. It is purely a read operation that retrieves and processes existing task information from the TickTick API.
From the tool's definition Tool description states it 'extracts keywords from tasks' (extract_task_keywords) with output of 'keyword frequency dictionary'. Arguments include 'limit' (number of keywords to return) and 'force_refresh' (whether to refresh cached data).
Documented attack patterns abuse exactly the kind of access extract_task_keywords gives an agent:
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 extract_task_keywords:
{
"version": "1",
"default": "deny",
"tools": {
"extract_task_keywords": {}
}
}extract_task_keywords is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

从任务中提取关键词 (来自API) Args: limit: 返回的关键词数量 (默认20) force_refresh: 是否强制刷新缓存数据 (默认为 False) Returns: 关键词频率字典. It is categorised as a Read tool in the TickTick MCP Service MCP Server, which means it retrieves data without modifying state.
Register the TickTick MCP Service MCP server in PolicyLayer and add a rule for extract_task_keywords: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches TickTick MCP Service. Nothing to install.
extract_task_keywords is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the extract_task_keywords rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for extract_task_keywords. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
extract_task_keywords is provided by the TickTick MCP Service MCP server (galaxyxieyu/didatodolist-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from TickTick MCP Service, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
