convex_snapshot_schema
Capture a snapshot of the current schema.ts for later diffing. Stores table names, schema size, and timestamp. Use before and after schema changes to track what changed.

What convex_snapshot_schema does on Nodebench
AI agents call convex_snapshot_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_snapshot_schema is rated Low
This tool retrieves and records schema metadata (table names, size, timestamp) for comparison purposes. It is a read operation that gathers information about the current state without modifying data or triggering side effects. The snapshot is a passive capture mechanism used to enable later diffing, not to change or execute anything.
From the tool's definition Tool performs a snapshot capture operation described as storing table names, schema size, and timestamp for diffing purposes.
Attacks that exploit this kind of access
The rule that runs convex_snapshot_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_snapshot_schema, this is the rule to start with:
convex_snapshot_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_snapshot_schema call is checked against it from then on.
Questions about convex_snapshot_schema
Capture a snapshot of the current schema.ts for later diffing. Stores table names, schema size, and timestamp. Use before and after schema changes to track what changed. 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_snapshot_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_snapshot_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_snapshot_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_snapshot_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_snapshot_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.
