AI agents call get_note to retrieve information from GetNote MCP Server 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 note data without modifying, deleting, or executing operations. It has no capacity to change state or trigger external actions. The blast radius of misuse is limited to unauthorized information disclosure of notes the user can access, which is a low severity read operation.
From the tool's definition Tool description states it 'retrieves specified note details including body text, tags, attachments, audio transcriptions, web links, etc.' The verb '获取' (retrieve/fetch) and the nature of the operation (querying note content) indicate read-only data…
Documented attack patterns abuse exactly the kind of access get_note gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GetNote MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_note:
{
"version": "1",
"default": "deny",
"tools": {
"get_note": {}
}
}get_note is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the GetNote MCP Server MCP server in PolicyLayer and add a rule for get_note: 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 GetNote MCP Server. Nothing to install.
get_note 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 get_note 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 get_note. 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.
get_note is provided by the GetNote MCP Server MCP server (iswalle/getnote-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GetNote MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
