List all direct child notes of a given note using a deterministic Trilium search query. Returns child note summaries including noteId, title, type, mime, and dateModified, sorted by dateCreated desc then title.
AI agents call list_children_notes to retrieve information from TriliumNext Notes' 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 structured data (child note metadata) without creating, modifying, deleting, or executing any operations. The read-only nature, deterministic search query, and return of note summaries (noteId, title, type, mime, dateModified) confirm it as a Read category tool with low severity risk.
From the tool's definition Tool description explicitly states 'List all direct child notes' and 'Returns child note summaries' — purely a retrieval operation with no modification or execution of side effects.
Documented attack patterns abuse exactly the kind of access list_children_notes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and TriliumNext Notes' MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_children_notes:
{
"version": "1",
"default": "deny",
"tools": {
"list_children_notes": {}
}
}list_children_notes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all direct child notes of a given note using a deterministic Trilium search query. Returns child note summaries including noteId, title, type, mime, and dateModified, sorted by dateCreated desc then title. It is categorised as a Read tool in the TriliumNext Notes' MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TriliumNext Notes' MCP Server MCP server in PolicyLayer and add a rule for list_children_notes: 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 TriliumNext Notes' MCP Server. Nothing to install.
list_children_notes 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 list_children_notes 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 list_children_notes. 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.
list_children_notes is provided by the TriliumNext Notes' MCP Server MCP server (tan-yong-sheng/triliumnext-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
