What discover_infrastructure does on Nodebench
AI agents call discover_infrastructure 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.
Why discover_infrastructure is rated Low
This tool performs static analysis and scanning of a codebase to identify infrastructure patterns (agent loops, telemetry, evaluation systems, governance patterns). The verbs used ('scans', 'returns') indicate read-only operations that retrieve and report on existing structures without creating, modifying, deleting, or executing anything.
From the tool's definition Tool description states it "Scans for" and "Returns what exists" — purely informational discovery with no modification, deletion, or execution of code.
Attacks that exploit this kind of access
The rule that runs discover_infrastructure 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 discover_infrastructure, this is the rule to start with:
discover_infrastructure is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nodebench, apply this rule, and every discover_infrastructure call is checked against it from then on.
Questions about discover_infrastructure
Discover existing agent infrastructure in the codebase. Scans for agent loops, telemetry, evaluation, verification, multi-channel integrations, self-learning systems, and governance patterns. Returns what exists, what. It is categorised as a Read tool in the Nodebench MCP Server, which means it retrieves data without modifying state.
Register the Nodebench MCP server in PolicyLayer and add a rule for discover_infrastructure: 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.
discover_infrastructure 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 discover_infrastructure 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 discover_infrastructure. 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.
discover_infrastructure 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.
