AI agents call n2n_export_markdown to retrieve information from N2n Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name suggests a read/export operation that retrieves knowledge graph data and formats it as markdown, which is a non-destructive read-like operation. However, 'export' could also involve writing a file to disk. Given the empty description and the context of sibling tools (which include explicit read tools like n2n_read_graph and n2n_open_nodes), this is most likely a read/export operation.
From the tool's definition Tool name 'n2n_export_markdown' suggests exporting data to markdown format; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access n2n_export_markdown gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and N2n Memory, and nothing reaches the server without passing your rules. This is the rule we recommend for n2n_export_markdown:
{
"version": "1",
"default": "deny",
"tools": {
"n2n_export_markdown": {}
}
}n2n_export_markdown is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

n2n_export_markdown. It is categorised as a Read tool in the N2n Memory MCP Server, which means it retrieves data without modifying state.
Register the N2n Memory MCP server in PolicyLayer and add a rule for n2n_export_markdown: 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 N2n Memory. Nothing to install.
n2n_export_markdown 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 n2n_export_markdown 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 n2n_export_markdown. 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.
n2n_export_markdown is provided by the N2n Memory MCP server (n2ns/n2n-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from N2n Memory, 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.
