How to Use the NLM RxNorm (Drug Database) MCP in Mastra AI

Q: How do I configure the NLM RxNorm (Drug Database) with Mastra AI?

Initialize the client using @mastra/mcp and specify the Vinkius URL. Spread the tools directly into your agent definition using the Mastra MCP client so it can invoke findrxcuibystring during runs.

Q: Can Mastra AI handle human approval steps before querying the NLM RxNorm (Drug Database)?

Yes, you can set requireToolApproval on tools like getndcproperties to require manual confirmation. This keeps a clinician in the loop for critical medication checks.

Q: Can I run bulk drug class queries with this setup?

Yes, you can use findsimilarclassesbydruglist in a workflow step. This allows your agent to analyze entire groups of RxCUIs simultaneously.

Build resilient clinical workflows that map drug classes and NDCs using Mastra AI.

Perplexity

Automate Drug Classification with Mastra AI Workflows

The `get_class_by_rxnorm_drug_id` tool extracts the drug classes associated with any RxCUI. The Mastra AI framework can route this data through conditional branches to flag specific drug-class combinations. If a lookup fails, the framework retries the query using exponential backoff. This ensures your automated clinical checks remain highly reliable.

Verify NDC Statuses in Multi-Step Pipelines

The `get_ndc_status` tool tracks the active or inactive history of specific National Drug Codes. Your Mastra agents use this to audit formulary lists against current FDA data. By combining this with `find_related_ndcs`, your workflow automatically finds alternative codes when a specific package is retired. It handles complex medical logic without manual intervention.

Query Complex Relationships via this MCP Server

The `get_related_by_relationship` tool uncovers specific connections like generic-to-brand mappings. Mastra AI uses these relationships to build drug substitution pipelines. The agent uses `get_drugs` to fetch clinical products related to an ingredient name. This MCP Server gives your backend pipelines direct access to standardized NIH data.

Setup guide

Set up NLM RxNorm (Drug Database) 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 NLM RxNorm (Drug Database) 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: "nlm-rxnorm-drug-database-mcp-client",
  servers: {
    "nlm-rxnorm-drug-database-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent NLM RxNorm (Drug Database) transactions"
);
console.log(result.text);

Initialize the client using `@mastra/mcp` and specify the Vinkius URL. Spread the tools directly into your agent definition using the Mastra MCP client so it can invoke `find_rxcui_by_string` during runs.

Yes, you can set `requireToolApproval` on tools like `get_ndc_properties` to require manual confirmation. This keeps a clinician in the loop for critical medication checks.

Mastra's built-in workflow engine handles rate limits using automatic retries. If `get_rx_concept_properties` hits a rate limit, Mastra's MCP integration pauses and retries.

Yes, you can use `find_similar_classes_by_drug_list` in a workflow step. This allows your agent to analyze entire groups of RxCUIs simultaneously.

This MCP Server only processes non-proprietary drug names, RxCUIs, and NDCs. Vinkius executes all database requests inside ephemeral, zero-trust sandboxes to guarantee data isolation.
