全局语义搜索：在所有笔记中进行语义召回。适用场景：「搜一下」「找找我哪些笔记提到了 XX」。返回结果按相关度从高到低排序。需要 note.recall.read scope。
AI agents call recall 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 retrieves and queries data from notes using semantic search without any side effects or ability to modify state. It is a read-only retrieval operation that returns sorted results. The required scope 'note.recall.read' further confirms read-only access. No data creation, modification, deletion, or code execution capabilities are present.
From the tool's definition Tool description states '全局语义搜索：在所有笔记中进行语义召回' (global semantic search: semantic recall across all notes) and '返回结果按相关度从高到低排序' (returns results sorted by relevance).
Documented attack patterns abuse exactly the kind of access recall 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 recall:
{
"version": "1",
"default": "deny",
"tools": {
"recall": {}
}
}recall 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 recall: 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.
recall 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 recall 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 recall. 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.
recall 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.
