Read all attributes (labels and relations) for a note. View existing labels (#tags), template relations (~template), and note metadata. This tool provides read-only access to inspect current attributes assigned to any note. Returns structured data with labels, relations, and summary information.
AI agents call read_attributes 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 retrieves and queries attribute metadata for a note without causing side effects, mutations, or irreversible changes. It falls clearly under the Read category as it provides inspection capabilities only.
From the tool's definition Tool name 'read_attributes' and description explicitly states 'read-only access' to 'inspect current attributes'. Returns data about labels, relations, and metadata without modifying or deleting anything.
Documented attack patterns abuse exactly the kind of access read_attributes 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 read_attributes:
{
"version": "1",
"default": "deny",
"tools": {
"read_attributes": {}
}
}read_attributes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

This tool provides read-only access to inspect current attributes assigned to any note. Returns structured data with labels, relations, and summary information. 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 read_attributes: 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.
read_attributes 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 read_attributes 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 read_attributes. 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.
read_attributes 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.
