Generate code for managing Orbit chain validators, batch posters, and AnyTrust DAC keysets. Supports listing, adding, and removing validators.
AI agents use generate_validator_setup 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 generates code for managing validators on an Orbit chain, including adding and removing validators and managing DAC keysets. While the tool itself generates code (a Write operation), the operations it enables—validator management, batch poster configuration, and DAC keyset changes—are high-impact administrative actions on a blockchain's consensus/security layer.
From the tool's definition Generate code for managing Orbit chain validators, batch posters, and AnyTrust DAC keysets. Supports listing, adding, and removing validators.
Documented attack patterns abuse exactly the kind of access generate_validator_setup 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_validator_setup:
{
"version": "1",
"default": "deny",
"tools": {
"generate_validator_setup": {
"limits": [
{
"counter": "generate_validator_setup_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generate_validator_setup 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 code for managing Orbit chain validators, batch posters, and AnyTrust DAC keysets. Supports listing, adding, and removing validators. 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_validator_setup: 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_validator_setup 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_validator_setup 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_validator_setup. 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_validator_setup 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.
