AI agents call search_reminders to retrieve information from Python Apple MCP 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 reminder data based on text search criteria. It does not create, modify, delete, execute external code, or move money. The action is purely informational and reversible, consistent with the Read category for tools that retrieve data without side effects.
From the tool's definition Tool name 'search_reminders' and description 'Search for reminders containing the given text' indicate a query/retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access search_reminders gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Python Apple MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_reminders:
{
"version": "1",
"default": "deny",
"tools": {
"search_reminders": {}
}
}search_reminders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Search for reminders containing the given text. It is categorised as a Read tool in the Python Apple MCP MCP Server, which means it retrieves data without modifying state.
Register the Python Apple MCP server in PolicyLayer and add a rule for search_reminders: 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 Python Apple MCP. Nothing to install.
search_reminders 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_reminders 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_reminders. 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_reminders is provided by the Python Apple MCP server (jxnl/python-apple-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Python Apple MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
