Search for drugs by name. Returns results from RxNorm and FDA databases.
AI agents call search_drug to retrieve information from Pharmacy MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves medication information from established pharmaceutical reference databases (RxNorm, FDA). It performs a lookup/search operation with no data modification, code execution, or destructive capability. The context (pharmacy reference workflows, dosing calculations, drug interaction checking) confirms this is informational—supporting clinical decision-making rather than performing actions.
From the tool's definition Tool name 'search_drug' and description 'Search for drugs by name. Returns results from RxNorm and FDA databases.' indicate a query operation that retrieves and returns drug reference data without modifying, executing code, or causing side effects.

Register the Pharmacy MCP Server MCP server in PolicyLayer and add a rule for search_drug: 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 Pharmacy MCP Server. Nothing to install.
search_drug 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_drug 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_drug. 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.
