AI agents use update_note to create or update resources in GetNote MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GetNote MCP Server environment.
This tool modifies existing notes reversibly by updating their title, content, or tags. It does not delete data (which would be Destructive) nor execute arbitrary code (which would be Execute). The ability to overwrite tags and content makes it a Write operation.
From the tool's definition Tool description states it updates note properties: 'updates note title, content or tags' (更新已有笔记的标题、内容或标签). The description explicitly notes tags are replaced/overwritten (会覆盖原有标签), indicating modification of existing data.
Documented attack patterns abuse exactly the kind of access update_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 update_note:
{
"version": "1",
"default": "deny",
"tools": {
"update_note": {
"limits": [
{
"counter": "update_note_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_note stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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 update_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.
update_note is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_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 update_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.
update_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.
