WHAT IT DOES

What list_dimension_evidence does on Nodebench

AI agents call list_dimension_evidence to retrieve information from Nodebench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_dimension_evidence is rated Low

This tool retrieves historical evidence records from a DeepTrace dimension profile for audit purposes. It performs no data modification, deletion, or external operations. The blast radius of misuse is minimal—an agent could retrieve sensitive metadata about scoring logic, but cannot alter, delete, or trigger any actions. Classified as Read with low severity.

From the tool's definition Tool name contains 'list' and description states 'List the durable evidence rows' — retrieves/queries existing data without modification.

RECOMMENDED RULE

The rule that runs list_dimension_evidence safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nodebench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_dimension_evidence, this is the rule to start with:

list_dimension_evidence Allowed

list_dimension_evidence is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "version": "1",
  "default": "deny",
  "tools": {
    "list_dimension_evidence": {}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Nodebench, apply this rule, and every list_dimension_evidence call is checked against it from then on.

Questions about list_dimension_evidence

What does the list_dimension_evidence tool do? +

List the durable evidence rows behind a DeepTrace dimension profile. Useful for auditing why a score or availability status was assigned. It is categorised as a Read tool in the Nodebench MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_dimension_evidence? +

Register the Nodebench MCP server in PolicyLayer and add a rule for list_dimension_evidence: 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 Nodebench. Nothing to install.

What risk level is list_dimension_evidence? +

list_dimension_evidence is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_dimension_evidence? +

Yes. Add a rate_limit block to the list_dimension_evidence 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.

How do I block list_dimension_evidence completely? +

Set action: deny in the PolicyLayer policy for list_dimension_evidence. 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.

What MCP server provides list_dimension_evidence? +

list_dimension_evidence is provided by the Nodebench MCP server (nodebench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
