Live chemical data streams in AI SDK

Feed `get_bioactivity_summary` and `get_hazard_summary` results directly into your React components. Your users see toxicity metrics update as the model processes them. Stop waiting for full-page reloads. This MCP Server pipes data through your existing stream handlers, keeping your UI responsive during heavy chemical lookups.

Fast search for your AI SDK app

Trigger `search_chemical_by_name` or `search_chemical_by_casrn` from your front-end inputs. The model identifies the correct DTXSID instantly. Handle chemical identification requests without manual API integration. The tool abstracts the underlying endpoint communication, letting your code focus on data display.

Physical property lookups for SDK front-ends

Pull `get_physicochemical_properties` for instant display in your dashboard. Show melting points and logP values as the user interacts with your chemical explorer. Configure your environment to handle these calls via Edge Functions. You gain fast, serverless access to EPA data without managing custom backend proxies.

Setup guide

Set up EPA Computational Toxicology MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all EPA Computational Toxicology tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent EPA Computational Toxicology transactions",
});

console.log(text);
await mcpClient.close();

Common questions about EPA Computational Toxicology MCP in Vercel AI SDK

Install the MCP client and initialize the connection using your endpoint URL. From there, you simply pass the available tools into your generateText function to start querying chemical properties.

Yes. The server is designed to stream results, which fits perfectly with the SDK's ability to render tool outputs in real-time. Just map the tool results to your UI state.

It does. The transport layer is built for standard HTTP connections, making it compatible with Vercel's serverless runtime environment.

The server returns standard error codes if a search fails or a CASRN is invalid. You should catch these in your client-side logic to provide feedback to your users.

The server accesses public EPA databases. It does not store your private input queries, ensuring the chemical names you search remain local to your session.
