Live route streaming for Vercel AI SDK

Pipe routing data directly into your frontend components. When your users request a path, the Vercel AI SDK fetches data via `calculate_routing_line` and renders it without waiting for a full page refresh. This keeps your UI responsive. By streaming tool output, you avoid the standard loading spinner pattern and show the path as the coordinates arrive.

Search and autocomplete in the browser

Give your users address lookup capabilities using `search_map_places` and `search_autocomplete`. Your AI client handles the query and updates the UI state immediately. It handles bias parameters automatically. This ensures the results stay relevant to the user's current view or input history.

Distance matrices for real-time logistics

Calculate travel times between multiple points using `calculate_distance_matrix`. Your app can now display accurate ETAs by processing these results through the Vercel AI SDK. This works at the edge. The MCP Server provides the raw data, and your frontend renders the final logistics view for the end user.

Setup guide

Set up Jawg Maps (Location & Routing) 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 Jawg Maps (Location & Routing) 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 Jawg Maps (Location & Routing) transactions",
});

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

Common questions about Jawg Maps (Location & Routing) MCP in Vercel AI SDK

You pass the search tool to your generateText call. The Vercel AI SDK handles the execution of `search_map_places` and returns the location data to your app.

Yes, you use `calculate_routing_line` as a tool definition. The stream will populate the coordinates into your interface as they are generated.

It does. Since this MCP Server uses standard HTTP transport, it connects to your edge-deployed code without issues.

You provide an endpoint token during the client setup. The SDK attaches this to every request made to the server.

The server only touches specific GPS coordinates and address strings you send. It does not store your user session history or tracking logs.
