List calendar events within an inclusive date range (capped at 90 days). Returns a JSON array of
AI agents call ical__list_events to retrieve information from Mcp Ical Swift without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves calendar event data within a specified date range without creating, modifying, or deleting any events. It is a read-only query operation with no side effects. The 90-day cap further limits its scope. Severity is low because exposure of calendar event metadata poses minimal risk compared to other categories.
From the tool's definition Tool description states 'List calendar events' which is a query/retrieval operation. The word 'List' and the context of returning 'a JSON array of' events indicates data retrieval with no modification or side effects.
Attacks that exploit this kind of access
List calendar events within an inclusive date range (capped at 90 days). Returns a JSON array of. It is categorised as a Read tool in the Mcp Ical Swift MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ical Swift MCP server in PolicyLayer and add a rule for ical__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 Mcp Ical Swift. Nothing to install.
ical__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 ical__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 ical__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.
ical__list_events is provided by the Mcp Ical Swift MCP server (sealjay/mcp-ical-swift). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
