AI agents call get_goal 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 only queries and retrieves existing goal data by ID. It has no side effects and does not create, modify, or delete any data. This is a straightforward read operation that fits the 'Read' category, which covers tools that retrieve or query data without side effects (search, list, get, fetch).
From the tool's definition Tool name is 'get_goal' and description states it retrieves goal details (获取目标详情), returning goal information without modifying data.
Documented attack patterns abuse exactly the kind of access get_goal 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_goal:
{
"version": "1",
"default": "deny",
"tools": {
"get_goal": {}
}
}get_goal 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.
获取目标详情 Args: goal_id: 目标ID (任务ID) Returns: 目标详情. 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_goal: 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_goal 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_goal 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_goal. 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_goal 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.
