Lists product catalogs for a Meta business. Args: - business_id (string): The business ID - limit (number): Max results (1–100, default 25) Returns catalog IDs, names, product counts, and verticals.
AI agents call meta_list_product_catalogs to retrieve information from Meta MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval tool that queries and returns catalog metadata. It has no side effects—it does not create, modify, delete, execute code, or commit financial transactions. The worst-case misuse scenario (an AI agent listing all catalogs for a business) results in information disclosure, which is a low-severity risk compared to categories that modify state or trigger external actions.
From the tool's definition Tool name 'meta_list_product_catalogs' and description 'Lists product catalogs' indicate a query operation that retrieves data.
Documented attack patterns abuse exactly the kind of access meta_list_product_catalogs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Meta MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for meta_list_product_catalogs:
{
"version": "1",
"default": "deny",
"tools": {
"meta_list_product_catalogs": {}
}
}meta_list_product_catalogs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists product catalogs for a Meta business. Args: - business_id (string): The business ID - limit (number): Max results (1–100, default 25) Returns catalog IDs, names, product counts, and verticals. It is categorised as a Read tool in the Meta MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Meta MCP Server MCP server in PolicyLayer and add a rule for meta_list_product_catalogs: 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 Meta MCP Server. Nothing to install.
meta_list_product_catalogs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the meta_list_product_catalogs 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_list_product_catalogs. 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_list_product_catalogs is provided by the Meta MCP Server MCP server (oliverames/meta-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Meta MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
