Duplicates a lead form under the same (or another) Page.
AI agents use meta_ads_lead_forms_duplicate to create or update resources in Mureo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mureo environment.
Duplicating a lead form creates a new copy of an existing resource. This is a reversible write operation — the duplicate can be deleted afterward. It does not execute code, irreversibly destroy data, or move money. Severity is medium because duplicating lead forms at scale could clutter ad accounts or expose form configurations to unintended pages.

Documented attack patterns abuse exactly the kind of access meta_ads_lead_forms_duplicate gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mureo, and nothing reaches the server without passing your rules. This is the rule we recommend for meta_ads_lead_forms_duplicate:
{
"version": "1",
"default": "deny",
"tools": {
"meta_ads_lead_forms_duplicate": {
"limits": [
{
"counter": "meta_ads_lead_forms_duplicate_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}meta_ads_lead_forms_duplicate 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.

Duplicates a lead form under the same (or another) Page. It is categorised as a Write tool in the Mureo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mureo MCP server in PolicyLayer and add a rule for meta_ads_lead_forms_duplicate: 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 Mureo. Nothing to install.
meta_ads_lead_forms_duplicate 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 meta_ads_lead_forms_duplicate 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 meta_ads_lead_forms_duplicate. 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.
meta_ads_lead_forms_duplicate is provided by the Mureo MCP server (logly/mureo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mureo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
