WHAT IT DOES

What detect_repeated_questions does on Nodebench

AI agents call detect_repeated_questions 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 detect_repeated_questions is rated Low

This tool retrieves and analyzes data (causal_events) to detect patterns using Jaccard similarity clustering. It has no side effects, does not modify or delete data, does not execute code or external operations, and does not involve financial transactions. It is purely analytical/read-only, similar to search or query operations that examine existing information.

From the tool's definition Tool 'Analyze...to find patterns' and 'cluster repeated queries' — performs pattern detection and analysis on existing causal_events data without modification, deletion, or execution of external operations.

RECOMMENDED RULE

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

detect_repeated_questions Allowed

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

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

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 detect_repeated_questions call is checked against it from then on.

FAQ

Questions about detect_repeated_questions

What does the detect_repeated_questions tool do? +

Analyze causal_events to find patterns where the user/agent asks the same strategic question repeatedly. Uses Jaccard similarity on summary text to cluster repeated queries. 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 detect_repeated_questions? +

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

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

Can I rate-limit detect_repeated_questions? +

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

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

detect_repeated_questions 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.
