Create a new Synology Calendar event. Requires confirm=true.
AI agents use calendar_create_event to create or update resources in Synology Office — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Synology Office environment.
This tool creates (writes) a new calendar event, which is a reversible modification of data. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. The confirm requirement lowers severity from high to medium, as it provides a safety gate against accidental misuse by an AI agent, though a determined agent could still bypass it if authorized to set confirm=true.
From the tool's definition Tool name 'calendar_create_event' and description 'Create a new Synology Calendar event' explicitly indicate creation of calendar data. The 'Requires confirm=true' safeguard suggests awareness of potential misuse.
Documented attack patterns abuse exactly the kind of access calendar_create_event gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Synology Office, and nothing reaches the server without passing your rules. This is the rule we recommend for calendar_create_event:
{
"version": "1",
"default": "deny",
"tools": {
"calendar_create_event": {
"limits": [
{
"counter": "calendar_create_event_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}calendar_create_event stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a new Synology Calendar event. Requires confirm=true. It is categorised as a Write tool in the Synology Office MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Synology Office MCP server in PolicyLayer and add a rule for calendar_create_event: 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 Synology Office. Nothing to install.
calendar_create_event is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the calendar_create_event 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 calendar_create_event. 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.
calendar_create_event is provided by the Synology Office MCP server (vocweb/synology-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Synology Office, 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.
