AI agents call wb_audit to retrieve information from Workbench without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool generates an audit/reconciliation report showing clearing status, contract trust status, and submission suggestions. This is a read/query operation that retrieves and presents existing state information without modifying data. Severity is low as misuse would only expose internal workflow state.
From the tool's definition 模块对账报告(清算状态/契约信任状态/送审建议) — 'report', '状态' (status), '建议' (suggestions) indicate retrieval and display of audit/reconciliation information

模块对账报告(清算状态/契约信任状态/送审建议). It is categorised as a Read tool in the Workbench MCP Server, which means it retrieves data without modifying state.
Register the Workbench MCP server in PolicyLayer and add a rule for wb_audit: 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 Workbench. Nothing to install.
wb_audit 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 wb_audit 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 wb_audit. 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.
wb_audit is provided by the Workbench MCP server (nvrenshiren/workbench). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
wb_audit is one line of Workbench's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
