AI agents call check_cart_availability to retrieve information from Ikea without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and checks availability data (a query operation) with no side effects. It does not create, modify, delete, execute code, or commit financial transactions. The read-only nature of the server and the query-based functionality of checking availability clearly place this in the Read category with low severity risk.
From the tool's definition Tool description states 'Check whether all items in a shopping list are available' and server is explicitly 'Read-only MCP server'. The tool queries stock data without modifying, creating, or deleting any information.
Attacks that exploit this kind of access
Check whether all items in a shopping list are available in sufficient quantity at a single IKEA store. It is categorised as a Read tool in the Ikea MCP Server, which means it retrieves data without modifying state.
Register the Ikea MCP server in PolicyLayer and add a rule for check_cart_availability: 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 Ikea. Nothing to install.
check_cart_availability 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 check_cart_availability 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 check_cart_availability. 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.
check_cart_availability is provided by the Ikea MCP server (taejin5314/ikea-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
