WHAT IT DOES

What search_events does on Microsoft Graph MCP Server

AI agents call search_events to retrieve information from Microsoft Graph MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why search_events needs a policy

This tool queries calendar events and returns data without side effects. It performs information retrieval only, matching the Read category definition. Severity is low because unauthorized access to calendar summaries, while a privacy concern, does not enable destructive or financial harm at the tool level. The blast radius of misuse is limited to disclosure of existing calendar event metadata.

From the tool's definition Tool description states it 'Search[es] or list[s] calendar events by keywords' and 'Returns matching events with summary information.' The verb 'search' and 'list' are read operations that retrieve data without modification.

POLICY

How to control search_events

PolicyLayer is an MCP gateway — it sits between your AI agents and Microsoft Graph MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_events:

policy.json

{
  "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.

Create a free account and register Microsoft Graph MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
