Register the Aldi MCP Server MCP server in PolicyLayer and add a rule for check_product_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 Aldi MCP Server. Nothing to install.
check_product_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_product_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_product_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_product_availability is provided by the Aldi MCP Server MCP server (markswendsen-code/mcp-aldi). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
