Search Apple Notes by title and plaintext body. Returns stable IDs for follow-up read, update, move, and delete tools.
AI agents call notes_search to retrieve information from Apple Notes MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves information from Apple Notes without creating, modifying, deleting, or executing external operations. It is a read-only operation that queries existing data. While the server overall supports destructive operations (notes_delete), this specific tool only performs search and returns identifiers, making it a Read category tool with low severity.
From the tool's definition Tool description explicitly states 'Search Apple Notes by title and plaintext body' and 'Returns stable IDs for follow-up read, update, move, and delete tools.' The verb 'search' combined with 'returns' indicates pure data retrieval with no modification.

Search Apple Notes by title and plaintext body. Returns stable IDs for follow-up read, update, move, and delete tools. It is categorised as a Read tool in the Apple Notes MCP MCP Server, which means it retrieves data without modifying state.
Register the Apple Notes MCP server in PolicyLayer and add a rule for notes_search: 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 Apple Notes MCP. Nothing to install.
notes_search 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 notes_search 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 notes_search. 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.
notes_search is provided by the Apple Notes MCP server (taylorarndt/apple-notes-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
