AI agents call get_tags 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 retrieves and returns a list of tags from TickTick without modifying, creating, or deleting any data. It is a pure read operation with no capability to alter system state. The low severity reflects minimal risk from misuse—listing tags cannot harm user data.
From the tool's definition Tool name 'get_tags' and description '获取所有标签列表' (get all tags list) with return value '标签列表' (tags list) indicates data retrieval with no side effects.
Documented attack patterns abuse exactly the kind of access get_tags 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 get_tags:
{
"version": "1",
"default": "deny",
"tools": {
"get_tags": {}
}
}get_tags is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
获取所有标签列表 Returns: 标签列表. 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 get_tags: 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.
get_tags 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 get_tags 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 get_tags. 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.
get_tags 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.
