THE RISK

Why generate_orbit_config needs a policy

This tool generates configuration code for Orbit chain deployment. It produces code/config artifacts rather than executing deployments directly or moving funds. Code generation is a Write operation (creates new files/content).

From the tool's definition Generate configuration code for Orbit chain deployment. Supports chain config, AnyTrust DAC setup, and custom gas token configuration using @arbitrum/orbit-sdk.

How to control generate_orbit_config

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_orbit_config:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_orbit_config": {
      "limits": [
        {
          "counter": "generate_orbit_config_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_orbit_config 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.

Create a free account and register ARBuilder — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about generate_orbit_config

What does the generate_orbit_config tool do? +

Generate configuration code for Orbit chain deployment. Supports chain config, AnyTrust DAC setup, and custom gas token configuration using @arbitrum/orbit-sdk. 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.

How do I enforce a policy on generate_orbit_config? +

Register the ARBuilder MCP server in PolicyLayer and add a rule for generate_orbit_config: 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.

What risk level is generate_orbit_config? +

generate_orbit_config is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit generate_orbit_config? +

Yes. Add a rate_limit block to the generate_orbit_config 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.

How do I block generate_orbit_config completely? +

Set action: deny in the PolicyLayer policy for generate_orbit_config. 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.

What MCP server provides generate_orbit_config? +

generate_orbit_config 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.

Enforce policy on every ARBuilder tool call.

Start from ARBuilder, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
