Clear all authentication tokens (logout).
AI agents call ticktick_logout to permanently remove resources in TickTick MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing all authentication tokens is irreversible in the sense that the tokens are permanently destroyed and the session cannot be restored without re-authentication. This is a destructive operation on the auth state. If an AI agent triggers this unintentionally, the assistant loses all access to TickTick until OAuth2 re-authorization is performed, potentially disrupting ongoing workflows.

Clear all authentication tokens (logout). It is categorised as a Destructive tool in the TickTick MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the TickTick MCP Server MCP server in PolicyLayer and add a rule for ticktick_logout: 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_logout is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the ticktick_logout 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_logout. 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_logout is provided by the TickTick MCP Server MCP server (mostafasuliman/ticktick-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
