Generate a Next.js frontend with wagmi, RainbowKit, and DaisyUI for Arbitrum dApps. Includes wallet connection, contract hooks, and responsive UI components.
AI agents use generate_frontend to create or update resources in ARBuilder — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ARBuilder environment.
This tool creates new frontend application code and configuration files, which are reversible modifications to a codebase. It does not execute code, delete data, or move funds. While it generates code that will eventually be executed, the tool itself performs code generation (Write category) rather than code execution.
From the tool's definition Tool generates frontend code including Next.js configuration, React components, wallet integration, and UI elements. The verb 'Generate' and the scope of outputs (full frontend application files) indicate code creation and file generation.
Documented attack patterns abuse exactly the kind of access generate_frontend gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ARBuilder, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_frontend:
{
"version": "1",
"default": "deny",
"tools": {
"generate_frontend": {
"limits": [
{
"counter": "generate_frontend_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generate_frontend 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.

Generate a Next.js frontend with wagmi, RainbowKit, and DaisyUI for Arbitrum dApps. Includes wallet connection, contract hooks, and responsive UI components. It is categorised as a Write tool in the ARBuilder MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ARBuilder MCP server in PolicyLayer and add a rule for generate_frontend: 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 ARBuilder. Nothing to install.
generate_frontend 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 generate_frontend 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 generate_frontend. 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.
generate_frontend is provided by the ARBuilder MCP server (quantum3-labs/arbuilder). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ARBuilder, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
