Search events by title, location, notes, or attendees.
AI agents call search_events to retrieve information from Fantastical MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and searches calendar event data based on various criteria but does not create, modify, delete, or execute any actions. It is a read-only query operation with minimal security impact, suitable for calendar information discovery.
From the tool's definition Tool name 'search_events' and description 'Search events by title, location, notes, or attendees' indicate a query operation with no modification or deletion capability.
Documented attack patterns abuse exactly the kind of access search_events gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Fantastical MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_events:
{
"version": "1",
"default": "deny",
"tools": {
"search_events": {}
}
}search_events is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search events by title, location, notes, or attendees. It is categorised as a Read tool in the Fantastical MCP MCP Server, which means it retrieves data without modifying state.
Register the Fantastical MCP server in PolicyLayer and add a rule for search_events: 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 Fantastical MCP. Nothing to install.
search_events is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_events 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 search_events. 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.
search_events is provided by the Fantastical MCP server (jaydenk/fantastical-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Fantastical MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
