Start a focus/Pomodoro session
AI agents invoke ticktick_start_focus_session to trigger actions in TickTick MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
The tool triggers an action that initiates a focus session, which is an operation with real-world side effects (starting a timer, potentially affecting UI state, logging session data). While not destructive or financial, it goes beyond passive data retrieval (Read) or simple data modification (Write).
From the tool's definition Tool description states 'Start a focus/Pomodoro session' — this initiates an external operation (starting a timer/session) whose effects depend on execution context and user state.
Documented attack patterns abuse exactly the kind of access ticktick_start_focus_session gives an agent:
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_start_focus_session:
{
"version": "1",
"default": "deny",
"tools": {
"ticktick_start_focus_session": {
"limits": [
{
"counter": "ticktick_start_focus_session_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}ticktick_start_focus_session stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Start a focus/Pomodoro session. It is categorised as a Execute tool in the TickTick MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the TickTick MCP Server MCP server in PolicyLayer and add a rule for ticktick_start_focus_session: 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_start_focus_session is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the ticktick_start_focus_session 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_start_focus_session. 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_start_focus_session 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.
Free to start. No card required.
