Perplexity

Displaying Live Departures

When a user asks about buses or trains, call `get_live_bus_departures` or `get_live_train_departures`. You stream the results directly into your React components. This means users see departure times update instantly—no waiting for an API loader. It's perfect for Edge Functions because you get real-time data streaming back to the UI, making your application feel snappy and responsive.

Journey Planning & Fares

Need a user to plan a trip? Use `plan_public_transport_journey` to return step-by-step directions. You can also get price comparisons using `get_train_fares`. Stream the entire journey breakdown, including changes and total time, right as it renders. If you're handling multi-leg trips, make sure to include `get_train_service_details` so your agent knows the full calling pattern for accuracy.

Finding Nearby Locations

Don't just rely on addresses. Use `get_nearby_bus_stops` or `get_nearby_transport_places` when a user only provides GPS coordinates. Stream the list of options, including directions and names. This is better than requiring perfect input. Also check out `get_transport_by_postcode`. It lets you find all transit options just from a UK postcode, which saves users major headaches.

Setup guide

Set up TransportAPI Alternative 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 TransportAPI Alternative 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 TransportAPI Alternative transactions",
});

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