How to Use the GenBank/NCBI API MCP in Mastra AI

Q: How do I get sequence summaries for a list of UIDs using the GenBank/NCBI API in a Mastra AI workflow?

Your agent can iterate through a list of UIDs, calling getncbisummary for each. Mastra AI will manage the execution, and you can add an approval step to manually verify the data for each sequence if needed.

Perplexity

Automate Sequence Audits

The `search_ncbi_sequences` tool is the first step in your automated data validation workflow. Your Mastra AI agent can query for a set of sequence UIDs, and if the NCBI API is slow or fails, Mastra's engine automatically retries. You don't have to code that logic yourself. You can build a workflow that starts by calling `list_ncbi_databases` to confirm your target database exists. Then, it runs the search. This conditional logic ensures your pipeline doesn't crash just because a database name changed.

Reliable Data Ingestion

Use `get_ncbi_summary` to enrich your internal database. Your agent can fetch a summary for a given UID, and you can add a step in your Mastra workflow to approve it manually with `requireToolApproval` before it's written to your system. This gives you a human-in-the-loop for critical data. Before kicking off a big ingestion job, your first step should always be `check_api_status`. If the API is down, Mastra can branch the workflow to send a Slack notification and reschedule the job for later, preventing a cascade of failures.

Build Resilient MCP Server Workflows

This MCP Server abstracts away the complexity of the NCBI E-utilities API. You don't need to write custom parsers for their XML format; the server gives your agent clean JSON. Mastra AI can focus on the workflow logic, not the data transformation. Integrating is simple. You add the Vinkius URL to your Mastra AI client configuration. The agent automatically discovers the tools from this MCP. You can then build complex chains, like searching for a sequence and then getting its summary.

Setup guide

Set up GenBank/NCBI API 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 GenBank/NCBI API 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: "genbankncbi-api-mcp-client",
  servers: {
    "genbankncbi-api-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "GenBank/NCBI API Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to GenBank/NCBI API tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent GenBank/NCBI API transactions"
);
console.log(result.text);

Common questions about GenBank/NCBI API MCP in Mastra AI

Mastra AI's built-in retry logic with exponential backoff helps manage this. The server itself also queues requests to avoid hammering the NCBI API. For heavy use, you can build pauses into your workflow.

Absolutely. Your first step in the Mastra AI workflow should call `check_api_status`. Use a conditional branch: if the status is not 'operational', the workflow can terminate or send an alert.

Your agent can iterate through a list of UIDs, calling `get_ncbi_summary` for each. Mastra AI will manage the execution, and you can add an approval step to manually verify the data for each sequence if needed.

Your Mastra AI workflow can handle this. Add a conditional step that checks if the list of UIDs from `search_ncbi_sequences` is empty. If it is, the agent can log the failure or try a different query term.

Yes. All requests for sequence UIDs, summaries, and database lists are passed through an ephemeral, sandboxed environment on Vinkius. No query data is logged or stored, ensuring your research remains confidential.
