WHAT IT DOES

What classify_failure does on Nodebench

AI agents call classify_failure 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 classify_failure is rated Low

This tool analyzes and categorizes existing failure information for diagnostic purposes. It retrieves or interprets failure data to assign it to a taxonomy, which is a read operation. There are no indications that it modifies systems, executes commands, deletes data, or initiates financial transactions.

From the tool's definition The tool 'classify_failure' is described as tracking and organizing failure data by 'symptom, root cause, and system layer for structured triage.' The verb 'classify' and 'tracks' indicate data retrieval, analysis, and categorization without modification or…

RECOMMENDED RULE

The rule that runs classify_failure 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 classify_failure, this is the rule to start with:

classify_failure Allowed

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

policy.json

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

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 classify_failure call is checked against it from then on.

FAQ

Questions about classify_failure

What does the classify_failure tool do? +

Classify a failure by canonical system layer taxonomy. Tracks symptom, root cause, and system layer for structured triage. 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 classify_failure? +

Register the Nodebench MCP server in PolicyLayer and add a rule for classify_failure: 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 classify_failure? +

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

Can I rate-limit classify_failure? +

Yes. Add a rate_limit block to the classify_failure 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 classify_failure completely? +

Set action: deny in the PolicyLayer policy for classify_failure. 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 classify_failure? +

classify_failure 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.
