AI agents call list_recipes to retrieve information from Speclib without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries recipe data with no side effects. It is a passive listing operation that does not create, modify, delete, or execute anything. The blast radius of misuse is minimal—an agent listing recipes cannot cause harm beyond information disclosure of recipes already accessible to the authenticated user.
From the tool's definition Tool name is 'list_recipes' and description states it 'List all recipes' with no modification, deletion, or execution capability. Returns data only (public and private recipes for authenticated users).
Attacks that exploit this kind of access
List all recipes. Returns public recipes and, if authenticated, your private recipes. It is categorised as a Read tool in the Speclib MCP Server, which means it retrieves data without modifying state.
Register the Speclib MCP server in PolicyLayer and add a rule for list_recipes: 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 Speclib. Nothing to install.
list_recipes 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 list_recipes 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 list_recipes. 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.
list_recipes is provided by the Speclib MCP server (rang501/speclib-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
