How to Use the Postscript MCP in Vercel AI SDK

Q: How do I connect Postscript to Vercel AI SDK?

Install the @ai-sdk/mcp package and define your transport URL. Pass the resulting tools to your streamText function so the agent controls your subscribers.

Q: Can Vercel AI SDK stream Postscript campaign data to my frontend?

Yes. When the agent calls getcampaign, the response streams directly into your UI components. Users watch SMS metrics load in real-time.

Q: How do I manage Postscript webhooks with Vercel AI SDK?

Call createwebhook or deletewebhook via the agent. This sets up endpoints for delivery receipts and opt-out events instantly.

Perplexity

Manage subscribers from the frontend

The `create_subscriber` tool lets your Vercel AI SDK app add new users to SMS lists straight from your UI via this MCP server. You capture a phone number in a custom React component, and the agent fires it to Postscript instantly. Want to check an opt-in status? The `get_subscriber` and `update_subscriber` tools stream that profile data back to the user without a page reload. It keeps your interface fast and compliant with marketing rules.

Stream campaign analytics live

Fetching performance stats happens via the `list_campaigns` tool. Your agent pulls active broadcast metrics and streams the results directly into your Next.js dashboard. Users click on a specific broadcast, and the `get_campaign` tool retrieves the exact send counts and click rates. You build the UI, and the MCP integration handles the data layer.

Track automations and keywords

The `list_automations` tool exposes your active abandoned cart flows and welcome series. Your Vercel AI SDK client reads these triggers to show merchants exactly what texts go out automatically. You also get access to `list_keywords` for opt-in tracking. You build dynamic frontend views where marketers see exactly which keywords drive the most signups.

Setup guide

Set up Postscript 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 Postscript 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 Postscript transactions",
});

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