View current Selver.ee cart contents and total price.
AI agents call view_cart to retrieve information from Selver without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and displays existing cart information. It has no side effects, does not modify data, does not execute code or external operations, and does not involve financial transactions or destructive actions. It is a straightforward data retrieval operation with minimal risk.
From the tool's definition Tool name 'view_cart' and description 'View current Selver.ee cart contents and total price' indicate a read-only operation that retrieves and displays cart data without modifying it.
Documented attack patterns abuse exactly the kind of access view_cart gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Selver, and nothing reaches the server without passing your rules. This is the rule we recommend for view_cart:
{
"version": "1",
"default": "deny",
"tools": {
"view_cart": {}
}
}view_cart is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Selver MCP server in PolicyLayer and add a rule for view_cart: 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 Selver. Nothing to install.
view_cart 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 view_cart 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 view_cart. 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.
view_cart is provided by the Selver MCP server (martparve/selver-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Selver, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
