WHAT IT DOES

What calendar_list_events does on Dialogbrain

AI agents call calendar_list_events to retrieve information from Dialogbrain without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`query`	string	—	Free text search query to filter events.
`date_to`	string	—	End date/time to query (YYYY-MM-DD or ISO 8601 format). Defaults to 7 days from now. Alias: time_max.
`date_from`	string	—	Start date/time to query (YYYY-MM-DD or ISO 8601 format). Defaults to now. Alias: time_min.
`calendar_id`	string	—	Calendar ID to list events from. OMIT to use the agent's configured default calendar (or primary).
`max_results`	integer	—	Maximum number of events to return.

Parameters from the server's own tool schema.

RISK

Why calendar_list_events is rated Low

Even though calendar_list_events only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs calendar_list_events safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Dialogbrain, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For calendar_list_events, this is the rule to start with:

calendar_list_events Allowed

calendar_list_events is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "calendar_list_events": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Dialogbrain, apply this rule, and every calendar_list_events call is checked against it from then on.
