Search for events containing specific text
AI agents call search_events to retrieve information from macOS MCP Servers without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries calendar events based on search criteria without creating, modifying, or deleting any data. It has no side effects beyond returning matching results. The blast radius of misuse is minimal—an agent could retrieve sensitive calendar information, but this is a read-only operation with low severity.
From the tool's definition Tool name 'search_events' and description 'Search for events containing specific text' indicate a query operation with no modification or deletion of data.
Attacks that exploit this kind of access
Search for events containing specific text. It is categorised as a Read tool in the macOS MCP Servers MCP Server, which means it retrieves data without modifying state.
Register the macOS MCP Servers MCP server in PolicyLayer and add a rule for search_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 macOS MCP Servers. Nothing to install.
search_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 search_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 search_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.
search_events is provided by the macOS MCP Servers MCP server (tdisawas0github/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
