Check if a product is available for delivery to a specific address and see which stores carry it
AI agents call check_availability to retrieve information from Mcp Drizly without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries product availability and store location data based on an address parameter. It has no side effects—it does not create, modify, delete, execute code, or commit financial transactions. It is a straightforward lookup/read operation that matches the Read category pattern of 'search, list, get, fetch' operations.

Attacks that exploit this kind of access
Check if a product is available for delivery to a specific address and see which stores carry it. It is categorised as a Read tool in the Mcp Drizly MCP Server, which means it retrieves data without modifying state.
Register the Mcp Drizly MCP server in PolicyLayer and add a rule for check_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 Mcp Drizly. Nothing to install.
check_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_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_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_availability is provided by the Mcp Drizly MCP server (markswendsen-code/mcp-drizly). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
