AI agents call week_overview to retrieve information from Tick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and presents existing task/project data in an organized view format for planning purposes. No data is created, modified, deleted, or executed. It is a passive query operation that has no side effects on the underlying TickTick system.
From the tool's definition Tool description explicitly states it 'Return[s] a planning-oriented overview' of events, due tasks, and overdue tasks. The verb 'return' and the read-only nature of retrieving a summary view indicates data retrieval with no modification.
Attacks that exploit this kind of access
Return a planning-oriented overview split into events, due tasks, and overdue tasks. It is categorised as a Read tool in the Tick MCP Server, which means it retrieves data without modifying state.
Register the Tick MCP server in PolicyLayer and add a rule for week_overview: 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 Tick. Nothing to install.
week_overview 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 week_overview 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 week_overview. 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.
week_overview is provided by the Tick MCP server (kpihx/tick-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
