Power query specifically for drug labels. Can search ingredients, warnings, indications.
AI agents call search_drug_labels to retrieve information from OpenFDA FastMCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries publicly available FDA drug label information. It performs searches on structured data (ingredients, warnings, indications) without creating, modifying, deleting, or executing operations. The capability to search public health datasets presents minimal risk—an AI agent using this tool can only access information already publicly available through the FDA.
From the tool's definition Tool description states 'Power query specifically for drug labels. Can search ingredients, warnings, indications.' The verbs 'search' and the context of querying public health datasets indicate read-only retrieval of existing FDA drug label data with no…
Documented attack patterns abuse exactly the kind of access search_drug_labels gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenFDA FastMCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_drug_labels:
{
"version": "1",
"default": "deny",
"tools": {
"search_drug_labels": {}
}
}search_drug_labels is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Power query specifically for drug labels. Can search ingredients, warnings, indications. It is categorised as a Read tool in the OpenFDA FastMCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenFDA FastMCP Server MCP server in PolicyLayer and add a rule for search_drug_labels: 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 OpenFDA FastMCP Server. Nothing to install.
search_drug_labels 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_labels 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_labels. 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_drug_labels is provided by the OpenFDA FastMCP Server MCP server (suyashekhande/openfda-semantic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OpenFDA FastMCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
