AI agents call lookup_drug to retrieve information from Drug Landscape without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though lookup_drug only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Get the full profile of a single drug by canonical slug, brand name, or generic name. Returns mechanism of action, FDA-approved indications, common + serious side effects, drug interactions, clinical trials, patents, pricing, and sponsor. Use this whenever the user asks about a specific drug.. It is categorised as a Read tool in the Drug Landscape MCP Server, which means it retrieves data without modifying state.
Register the Drug Landscape MCP server in PolicyLayer and add a rule for lookup_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 Drug Landscape. Nothing to install.
lookup_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 lookup_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 lookup_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.
lookup_drug is provided by the Drug Landscape MCP server (james-h-millett/drug-landscape). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
