Compute % overlap between custom audiences in the connected ad account.
AI agents call wafle_ads_audience_overlap_check to retrieve information from wafle MCP server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and computes analytics on existing custom audiences in an ad account. It produces a read-only analysis (percentage overlap) with no side effects, data modification, code execution, or destructive capability. The operation is purely informational and safe for autonomous agents to invoke.
From the tool's definition Tool name contains 'check' and description states 'Compute % overlap' — a computational query operation that retrieves and analyzes existing audience data without modifying, executing external operations, or deleting data.
Attacks that exploit this kind of access
Compute % overlap between custom audiences in the connected ad account. It is categorised as a Read tool in the wafle MCP server MCP Server, which means it retrieves data without modifying state.
Register the wafle MCP server MCP server in PolicyLayer and add a rule for wafle_ads_audience_overlap_check: 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 wafle MCP server. Nothing to install.
wafle_ads_audience_overlap_check 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 wafle_ads_audience_overlap_check 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 wafle_ads_audience_overlap_check. 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.
wafle_ads_audience_overlap_check is provided by the wafle MCP server MCP server (the33warehouse-tech/wafle-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
