List events from a Google Calendar within an optional time window.
AI agents call list-events to retrieve information from Universal Mcp Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves calendar event data within an optional time window. It has no side effects: it does not create, modify, delete, or execute any operations. The action is purely informational (Read category).
From the tool's definition Tool name is 'list-events' and description states 'List events from a Google Calendar' — a retrieval operation with no modification, deletion, or execution of external actions.
Attacks that exploit this kind of access

Register the Universal Mcp Toolkit 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 Universal Mcp Toolkit. 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 Universal Mcp Toolkit MCP server (markgatcha/universal-mcp-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
