AI agents call ticktick_filter_tasks to retrieve information from TickTick MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Filtering tasks is a read/query operation that retrieves tasks matching specified criteria without modifying any data. No side effects are implied.

PolicyLayer is an MCP gateway — it sits between your AI agents and TickTick MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for ticktick_filter_tasks:
{
"version": "1",
"default": "deny",
"tools": {
"ticktick_filter_tasks": {}
}
}ticktick_filter_tasks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Filter tasks by various criteria. It is categorised as a Read tool in the TickTick MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TickTick MCP Server MCP server in PolicyLayer and add a rule for ticktick_filter_tasks: 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 Server. Nothing to install.
ticktick_filter_tasks 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 ticktick_filter_tasks 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 ticktick_filter_tasks. 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.
ticktick_filter_tasks is provided by the TickTick MCP Server MCP server (liadgez/ticktick-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from TickTick MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
