WHAT IT DOES

What log_gap does on Nodebench

AI agents use log_gap to create or update resources in Nodebench, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nodebench environment.

RISK

Why log_gap is rated Medium

This tool creates and stores gap analysis records (Write category). It does not execute code, delete data, or involve financial transactions. The blast radius is low since it only logs metadata about identified gaps and does not modify or affect any underlying systems or data beyond recording the gap entry itself.

From the tool's definition 'Record a gap found during Phase 2 (Gap Analysis)' — the tool writes/creates a gap record categorized by severity levels

Attacks that exploit this kind of access

RECOMMENDED RULE

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

log_gap Rate-limited

log_gap stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. 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 log_gap call is checked against it from then on.

FAQ

Questions about log_gap

What does the log_gap tool do? +

Record a gap found during Phase 2 (Gap Analysis). Gaps are categorized by severity: CRITICAL (protocol violations, security), HIGH (API incompatibilities), MEDIUM (outdated versions), LOW (edge cases). It is categorised as a Write tool in the Nodebench MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on log_gap? +

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

log_gap is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit log_gap? +

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

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

log_gap 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.
