Generate HTML design from task + confirmed decisions
AI agents use generate_design to create or update resources in BWVI — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your BWVI environment.
This tool creates new HTML artifacts based on inputs, which constitutes a Write action—data creation that is reversible. It does not execute arbitrary code (Execute), delete data (Destructive), move money (Financial), or merely retrieve information (Read).
From the tool's definition Tool generates HTML design output from task and confirmed decisions. The description uses 'Generate' which indicates content creation/modification.
Documented attack patterns abuse exactly the kind of access generate_design gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and BWVI, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_design:
{
"version": "1",
"default": "deny",
"tools": {
"generate_design": {
"limits": [
{
"counter": "generate_design_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generate_design 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 HTML design from task + confirmed decisions. It is categorised as a Write tool in the BWVI MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the BWVI MCP server in PolicyLayer and add a rule for generate_design: 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 BWVI. Nothing to install.
generate_design 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_design 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_design. 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_design is provided by the BWVI MCP server (lh123aa/bwvi-design). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from BWVI, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
