AI agents call search_items to retrieve information from Sana without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search operations retrieve or query data without side effects. The tool fits the Read category pattern established by sibling search/lookup tools on this inventory and trip management server. No modifications, deletions, or external execution occurs.
From the tool's definition Tool name 'search_items' indicates a query/search operation with no modification verb. Sibling tools include 'search_discard_history', 'search_trips', and 'lookup_trip_details' which are clearly Read operations on the same server.
Attacks that exploit this kind of access
search_items. It is categorised as a Read tool in the Sana MCP Server, which means it retrieves data without modifying state.
Register the Sana MCP server in PolicyLayer and add a rule for search_items: 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 Sana. Nothing to install.
search_items 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 search_items 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 search_items. 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.
search_items is provided by the Sana MCP server (sana-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
