Diagnoses root causes of rising spend or degrading CPA on a
AI agents call meta_ads_analysis_cost to retrieve information from Mureo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes existing Meta Ads performance metrics (cost, CPA trends) to identify root causes. It performs read-only diagnostic analysis without creating, modifying, executing scripts against external systems, or deleting data. The output is insight generation based on querying existing advertising account data.
From the tool's definition Tool name 'meta_ads_analysis_cost' and description 'Diagnoses root causes of rising spend or degrading CPA' indicate analysis and diagnostic querying of Meta Ads performance data.

Documented attack patterns abuse exactly the kind of access meta_ads_analysis_cost 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_analysis_cost:
{
"version": "1",
"default": "deny",
"tools": {
"meta_ads_analysis_cost": {}
}
}meta_ads_analysis_cost is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Diagnoses root causes of rising spend or degrading CPA on a. It is categorised as a Read tool in the Mureo MCP Server, which means it retrieves data without modifying state.
Register the Mureo MCP server in PolicyLayer and add a rule for meta_ads_analysis_cost: 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_analysis_cost 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_ads_analysis_cost 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_analysis_cost. 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_analysis_cost 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.
