AI agents call search_behaviors to retrieve information from Meta Ads MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a data retrieval tool that queries Meta's advertising API to fetch behavior targeting metadata. The operation is non-destructive and produces no side effects—it merely lists available targeting parameters without modifying any campaigns, budgets, or ad content. The parameters (access_token, limit) control what existing data is returned, not what is changed.
From the tool's definition The tool description explicitly states it retrieves 'available behavior targeting options' with no modification, creation, or deletion capabilities.
Documented attack patterns abuse exactly the kind of access search_behaviors gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Meta Ads MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_behaviors:
{
"version": "1",
"default": "deny",
"tools": {
"search_behaviors": {}
}
}search_behaviors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all available behavior targeting options. Args: access_token: Meta API access token (optional - will use cached token if not provided) limit: Maximum number of results to return (default: 50) Returns: JSON string containing behavior targeting options with id, name, audience_size bounds, path, and description. It is categorised as a Read tool in the Meta Ads MCP MCP Server, which means it retrieves data without modifying state.
Register the Meta Ads MCP server in PolicyLayer and add a rule for search_behaviors: 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 Ads MCP. Nothing to install.
search_behaviors 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 search_behaviors 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 search_behaviors. 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.
search_behaviors is provided by the Meta Ads MCP server (pipeboard-co/meta-ads-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
