cookbook
AI agents call cookbook to retrieve information from Vector Memory MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name suggests retrieval of pre-stored knowledge/examples rather than creation, modification, or deletion. Sibling tools show the server provides list, search, and get operations typical of read-only memory access. Without a description, confidence is moderately reduced, but the semantic memory context and naming convention strongly suggest this is a read operation.
From the tool's definition Tool name 'cookbook' with empty description. Based on server context (semantic memory, knowledge organization), 'cookbook' most likely retrieves stored recipes, code snippets, or documented solutions—a read-only reference pattern.
Attacks that exploit this kind of access
cookbook. It is categorised as a Read tool in the Vector Memory MCP MCP Server, which means it retrieves data without modifying state.
Register the Vector Memory MCP server in PolicyLayer and add a rule for cookbook: 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 Vector Memory MCP. Nothing to install.
cookbook 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 cookbook 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 cookbook. 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.
cookbook is provided by the Vector Memory MCP server (xsaven/vector-memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
