AI agents call get_profiles to retrieve information from Klaviyo 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 or queries profile data from Klaviyo without modifying, deleting, or executing operations. Despite the empty description, the naming convention and server context indicate a read-only operation. Severity is low because unauthorized profile retrieval, while a privacy concern, does not directly enable destructive or financial actions by itself.
From the tool's definition Tool name 'get_profiles' indicates retrieval of profile data. Server context describes managing profiles, lists, segments, and campaigns with the Klaviyo API.
Documented attack patterns abuse exactly the kind of access get_profiles gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Klaviyo MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_profiles:
{
"version": "1",
"default": "deny",
"tools": {
"get_profiles": {}
}
}get_profiles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_profiles. It is categorised as a Read tool in the Klaviyo MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Klaviyo MCP Server MCP server in PolicyLayer and add a rule for get_profiles: 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 Klaviyo MCP Server. Nothing to install.
get_profiles 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 get_profiles 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 get_profiles. 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.
get_profiles is provided by the Klaviyo MCP Server MCP server (mattcoatsworth/klaviyo-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Klaviyo MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
