What convex_audit_schema does on Nodebench
AI agents call convex_audit_schema 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 convex_audit_schema is rated Low
Analysis tools retrieve and examine data structures without modifying them, fitting the Read category. Severity is medium rather than low because schema analysis could expose sensitive information about data models, authentication patterns, or business logic embedded in a Convex backend, which could inform further attacks. However, it performs no direct data access, code execution, or destructive action on its own.
From the tool's definition Tool name and description indicate 'Analyze a Convex project' — an inspection/analysis operation with no modification capability. Convex is a backend platform, and analyzing a schema is a read-only introspection task.
Attacks that exploit this kind of access
The rule that runs convex_audit_schema 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 convex_audit_schema, this is the rule to start with:
convex_audit_schema 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 convex_audit_schema call is checked against it from then on.
Questions about convex_audit_schema
Analyze a Convex project. 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 convex_audit_schema: 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.
convex_audit_schema 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 convex_audit_schema 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 convex_audit_schema. 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.
convex_audit_schema 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.
