convex_generate_plan
Generate a Convex-specific implementation plan for missing code signatures. Takes the gap analysis from convex_verify_concept and produces step-by-step instructions with Convex-aware injection strategies (schema changes, function registration, auth guards, index creation, etc.).

What convex_generate_plan does on Nodebench
AI agents use convex_generate_plan 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.
Why convex_generate_plan is rated Medium
The tool generates implementation plans that involve creating or modifying code-level artifacts (schemas, functions, guards, indexes). While it produces instructions rather than directly executing them, it is fundamentally a Write operation: it creates new configuration/code artifacts within a Convex system.
From the tool's definition Tool description explicitly mentions 'schema changes, function registration, auth guards, index creation' and 'produces step-by-step instructions' for code implementation. These are modifications to a system's data structures and configuration.
Attacks that exploit this kind of access
The rule that runs convex_generate_plan 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_generate_plan, this is the rule to start with:
convex_generate_plan 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 convex_generate_plan call is checked against it from then on.
Questions about convex_generate_plan
Generate a Convex-specific implementation plan for missing code signatures. Takes the gap analysis from convex_verify_concept and produces step-by-step instructions with Convex-aware injection strategies (schema changes, function registration, auth guards, index creation, etc.). 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.
Register the Nodebench MCP server in PolicyLayer and add a rule for convex_generate_plan: 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_generate_plan is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the convex_generate_plan 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_generate_plan. 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_generate_plan 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.
