What todaysMenu does on Genkit MCP
AI agents call todaysMenu to retrieve information from Genkit MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why todaysMenu is rated Low
This tool queries and returns information about today's menu items. It performs a read-only retrieval operation without creating, modifying, deleting, or executing any operations. The low severity reflects minimal blast radius—an AI agent misusing this tool could at worst retrieve menu data it shouldn't have access to, but cannot cause data loss, code execution, or financial harm.
From the tool's definition Tool name 'todaysMenu' and description 'retrieve all the items on today' indicate a data retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
The rule that runs todaysMenu safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Genkit MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For todaysMenu, this is the rule to start with:
todaysMenu is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Genkit MCP, apply this rule, and every todaysMenu call is checked against it from then on.
