What critter_check does on Nodebench
AI agents call critter_check 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 critter_check is rated Low
The tool appears designed to retrieve or query information (likely related to task status, progress, or accountability metrics) based on its framing as an 'accountability partner' that seeks information via 'answer'. The lack of any action verbs (create, delete, execute, pay) and the emphasis on gathering/knowing information classifies this as a Read operation.
From the tool's definition Tool name 'critter_check' and description 'accountability partner that wants to know everything — answer' suggests information gathering and querying for accountability purposes. No modification, execution, deletion, or financial operations are implied.

The rule that runs critter_check 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 critter_check, this is the rule to start with:
critter_check 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 critter_check call is checked against it from then on.
Questions about critter_check
The accountability partner that wants to know everything — answer. 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 critter_check: 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.
critter_check 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 critter_check 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 critter_check. 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.
critter_check 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.
