AI agents use batch_add_notes_to_topic 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.
The tool creates associations between notes and topics, which modifies the state of the knowledge base structure. While reversible (tags and topic assignments can be removed), it affects multiple records at once. Severity is medium because the blast radius is limited to note organization/metadata; there is no destructive capability, financial impact, or code execution.
From the tool's definition Tool name 'batch_add_notes_to_topic' and description '批量将笔记添加到知识库（每批最多 20 个）' (batch add notes to knowledge base, up to 20 per batch) indicate creation/modification of relationships between notes and topics.
Risk signalsBulk/mass operation — affects multiple targets
Documented attack patterns abuse exactly the kind of access batch_add_notes_to_topic 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 batch_add_notes_to_topic:
{
"version": "1",
"default": "deny",
"tools": {
"batch_add_notes_to_topic": {
"limits": [
{
"counter": "batch_add_notes_to_topic_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}batch_add_notes_to_topic 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.

批量将笔记添加到知识库（每批最多 20 个）。. It is categorised as a Write tool in the GetNote MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the GetNote MCP Server MCP server in PolicyLayer and add a rule for batch_add_notes_to_topic: 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.
batch_add_notes_to_topic 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 batch_add_notes_to_topic 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 batch_add_notes_to_topic. 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.
batch_add_notes_to_topic 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.
