list_events
AI agents call list_events to retrieve information from Google Calendar MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list_events' tool retrieves or queries calendar event data with no side effects. It follows the Read category pattern of listing/fetching information. While the description is empty, the name is sufficiently clear and consistent with standard CRUD terminology where 'list' operations are universally read-only.
From the tool's definition Tool name 'list_events' indicates retrieval of calendar events. Sibling tools include create_event, delete_event, update_event, and get_event; list_events aligns with the Read pattern of querying/retrieving data without modification.
Attacks that exploit this kind of access
list_events. It is categorised as a Read tool in the Google Calendar MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Google Calendar MCP Server MCP server in PolicyLayer and add a rule for list_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 Google Calendar MCP Server. Nothing to install.
list_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 list_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 list_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.
list_events is provided by the Google Calendar MCP Server MCP server (volodymyrkoval/fastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
