25 tools. 6 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.
Last updated:
Destructive tools (calendar_v3_delete_event) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (calendar_v3_create_event, calendar_v3_quick_add, calendar_v3_update_event) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Intercept sits between your agent and Google Calendar and Meet. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

- action: deny Destructive tools should never be available to autonomous agents without human approval.
calendar_v3_create_event:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.

rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Google Calendar and Meet server exposes 1 destructive tools including calendar_v3_delete_event. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Google Calendar and Meet server has 5 write tools including calendar_v3_create_event, calendar_v3_quick_add, calendar_v3_update_event. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.
25 tools across 3 categories: Destructive, Read, Write. 19 are read-only. 6 can modify, create, or delete data.
One line change. Instead of running the Google Calendar and Meet server directly, prefix it with Intercept: intercept -c inside-hair-mcp-google-meet-and-calendar.yaml -- npx -y @INSIDE-HAIR/mcp-google-meet-and-calendar. Download a pre-built policy from policylayer.com/policies/inside-hair-mcp-google-meet-and-calendar and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
Set budgets, approvals, and hard limits across MCP servers.
