AI agents call check_drug to retrieve information from Pharma Regulatory 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 check_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.

Retrieve pharmaceutical regulatory reference data for a drug, medicine, or active ingredient across multiple authoritative datasets. Input: drug brand name, generic active ingredient, or CAS number (e.g. 'metformin', 'ibuprofen', '50-78-2'). Returns: DrugBank compound data (ID, groups, targets, SMILES, DDI count), WHO Essential Medicines listing (ATC code, formulations, indications, dosage, contraindications, pregnancy safety), Australian TGA ARTG records (ARTG ID, sponsor, category, schedule, dosage form, route, indications), and FDA NDI notifications (NDI number, FDA response, intended use). Sources: DrugBank (4,947 compounds), WHO EML, Australian TGA ARTG (23,259 medicines), FDA NDI (1,330 notifications). For pharmaceutical regulatory compliance and drug safety reference. Do not use for drug-drug interactions (use check_drug_interactions), adverse events (use check_adverse_events), or cosmetic/food/cannabis substances.. It is categorised as a Read tool in the Pharma Regulatory MCP Server, which means it retrieves data without modifying state.
Register the Pharma Regulatory MCP server in PolicyLayer and add a rule for check_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 Pharma Regulatory. Nothing to install.
check_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 check_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 check_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.
check_drug is provided by the Pharma Regulatory MCP server (https://pharma-mcp-server.rootsbybenda.workers.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
