How to Use the Google Roads MCP in Vercel AI SDK

Q: How do I configure Google Roads with Vercel AI SDK?

Install @ai-sdk/mcp and initialize the client using the Vinkius endpoint. You then pass the tools directly into streamText to let your agent call this MCP server.

Q: What is the coordinate limit for path snapping?

The snaptoroads tool accepts up to 100 coordinate pairs in a single request. If your Vercel AI SDK client receives a larger track, you must chunk the coordinates into smaller batches before sending them to this MCP server.

Map-match messy GPS tracks and fetch speed limits in real-time streams using Google Roads inside your Vercel AI SDK application.

Clean up raw GPS traces with Vercel AI SDK

The `snap_to_roads` tool cleans up noisy coordinate streams by snapping raw GPS points directly to the actual roads traveled. When users upload route logs, your Vercel AI SDK client calls this endpoint to return clean, interpolated path points for immediate mapping. Your application streams these corrected coordinates straight to the client UI. Instead of waiting for a massive payload to finish processing, your users watch the messy map lines snap into clean roads in real-time.

Get speed limits instantly using this MCP Server

The `get_speed_limits` tool gets legal speed limits for specific road segments using place IDs. Your Vercel AI SDK client queries this endpoint to display speed data alongside active routes. Because this runs inside Vercel's Edge runtime, you get minimal latency. Your streaming frontend shows the legal speed limit the second a user clicks a point on the map, skipping slow backend hops.

Snap routes and pull speed limits in one call

The `get_snapped_speed_limits` tool combines path snapping and speed limit fetching into a single query. Pass a driver's trip history to this tool to retrieve both coordinates and speed limits simultaneously. This single-call structure prevents round-trip lag. Your streaming UI displays the snapped route and speed violations side-by-side without triggering multiple slow API requests to the MCP server.

Setup guide

Set up Google Roads 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 Google Roads 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 Google Roads transactions",
});

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

Common questions about Google Roads MCP in Vercel AI SDK

Install `@ai-sdk/mcp` and initialize the client using the Vinkius endpoint. You then pass the tools directly into `streamText` to let your agent call this MCP server.

Yes, you can stream the snapped coordinates directly to your React or Next.js map components. The `snap_to_roads` tool returns clean coordinates that your agent pipes to the frontend without waiting for the full API response.

The SDK catches API errors during runtime and passes them through the standard stream error handler. If `get_nearest_roads` fails due to an invalid coordinate, your agent can catch the exception and prompt the user to correct the input.

The `snap_to_roads` tool accepts up to 100 coordinate pairs in a single request. If your Vercel AI SDK client receives a larger track, you must chunk the coordinates into smaller batches before sending them to this MCP server.

Your raw GPS coordinates and place IDs are processed in Vinkius's secure V8 isolates before hitting the Google Roads endpoint. No location data is stored permanently on our servers, ensuring your fleet's tracking history remains private.
