Severity is medium rather than low because (1) the 'power_query' designation and 'ALL endpoints' access suggests broad data access that could expose sensitive medical information at scale, and (2) unrestricted querying of comprehensive drug adverse event data could enable…

From the tool's definition Tool name contains 'search' and description states 'direct access to ALL drug API endpoints' for querying FDA data. No creation, modification, deletion, execution, or financial operations described.

POLICY

How to control search_drug_power_query

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_power_query:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_drug_power_query": {}
  }
}

search_drug_power_query is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register OpenFDA FastMCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
