@gws mcp -s calendar Write Risk 3/5

// WHEN AI AGENTS USE THIS TOOL

AI agents use calendar_calendarList_insert to create or modify resources in Google Workspace Calendar (gws CLI). Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON CALENDAR_CALENDARLIST_INSERT

Without a policy, an AI agent could call calendar_calendarList_insert repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Google Workspace Calendar (gws CLI).

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

  calendar_calendarList_insert:
