Automate drug label audits in Mastra-AI

Plug `search_drug_labels` into your agent workflows to pull structured product labeling data based on your specific logic. It handles the API handshake so your agent can focus on the analysis. If the data retrieval fails, your Mastra-AI workflow can catch the error and retry. It keeps your pipeline moving even when the upstream data source hits a hiccup.

Conditional analysis of FDA data

Use `count_drug_labels` inside your agent steps to trigger conditional branches. If the record count for a specific drug class exceeds your threshold, the agent can escalate the task. This allows for automated monitoring of drug labeling changes. You define the logic, and the tools provide the raw numbers to drive the decision.

Secure agent-based data extraction

The server exposes focused tools for your agents to execute specific tasks. It minimizes the surface area of your integration by only allowing defined API calls. You control what the agent can see. It enforces a strict boundary between your workflow logic and the openFDA data provider.

Setup guide

Set up FDA Drug Labels (openFDA) MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All FDA Drug Labels (openFDA) tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "fda-drug-labels-openfda-mcp-client",
  servers: {
    "fda-drug-labels-openfda-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "FDA Drug Labels (openFDA) Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to FDA Drug Labels (openFDA) tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent FDA Drug Labels (openFDA) transactions"
);
console.log(result.text);
