Look up an inventory item by its SKU code. Returns full item details including stock, location, and pricing. Requires API key.
AI agents call lookup_sku to retrieve information from CerebroChain MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
lookup_sku retrieves and queries inventory data (stock levels, location, pricing) without side effects. It matches the Read category pattern (search, list, get, fetch). The API key requirement is a standard authentication control and does not elevate the risk category.
From the tool's definition Tool description states it 'Look up an inventory item' and 'Returns full item details' — pure data retrieval with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Look up an inventory item by its SKU code. Returns full item details including stock, location, and pricing. Requires API key. It is categorised as a Read tool in the CerebroChain MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CerebroChain MCP Server MCP server in PolicyLayer and add a rule for lookup_sku: 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 CerebroChain MCP Server. Nothing to install.
lookup_sku 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 lookup_sku 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 lookup_sku. 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.
lookup_sku is provided by the CerebroChain MCP Server MCP server (cerebrochain/cerebrochain-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
