How to Use the FreeClimb MCP in Vercel AI SDK

Q: How do I stream FreeClimb SMS logs in Vercel AI SDK?

You configure the MCP client to use the listsmsmessages tool inside your Next.js route. The tools stream raw message arrays directly to the useChat hook, updating your UI instantly.

Q: Can I trigger a FreeClimb call directly from a Vercel AI SDK chat interface?

Yes. Your agent invokes the makecall tool when a user requests an outbound dial. The SDK handles the tool execution block and returns the call metadata to the user.

Q: How do I track my API balance?

Call the getaccountstatus tool. This returns your real-time balance and account tier directly to your agent.

Stream real-time FreeClimb call and SMS data directly into your React components using the Vercel AI SDK and this MCP server.

Live Call Tracking in Vercel AI SDK Frontends

This MCP Server exposes the `list_calls` and `get_call_details` tools to feed active call telemetry straight into your streaming UI. Your Vercel AI SDK setup catches these events and updates the interface without forcing the user to wait for a full page reload. By bypassing intermediate backend databases, you display raw status changes immediately. You get clean, event-driven updates on active dial states directly inside your web application.

Interactive SMS Dispatch and History

The `send_sms` and `list_sms_messages` tools let your frontend agent send texts and display chat histories on the fly. Users watch the outgoing message status update from queued to delivered inside their browser window. Coupling this with Vercel's Edge Functions means you avoid cold-start delays. The interface reflects outbound SMS activity in milliseconds, keeping the user in the loop.

Number Management via Vercel UI Components

With `list_buyable_numbers` and `list_my_numbers`, your agent searches available inventory and displays available options inside your React layout. The user selects a number, and the agent reserves it instantly. You don't have to build custom search forms or tables. The MCP tool returns raw phone number options that your Vercel AI SDK agent formats on the fly.

Setup guide

Set up FreeClimb 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 FreeClimb 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 FreeClimb transactions",
});

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