How to Use the Handlebars Template Compiler MCP in Vercel AI SDK

Q: Does this Handlebars Template Compiler support conditional loops in Vercel AI SDK?

Yes, it does. The compiletemplate tool handles nested arrays and conditional blocks natively. Your agent just feeds it the JSON payload.

Render clean HTML templates live in your Vercel AI SDK stream without letting LLMs break the syntax.

Stop broken HTML streams in Vercel AI SDK

LLMs are terrible at raw string replacement. When you stream UI components, a single missing bracket ruins the layout. This MCP Server lets your agent delegate the compilation to a real engine. By calling `compile_template` directly inside your Next.js edge route, the server outputs safe, compiled HTML. Your users see the final rendered email or card instantly, without the typical streaming glitches.

Fast edge compilation for real-time UI

Heavy rendering libraries slow down edge functions. This tool offloads the template processing entirely, keeping your Vercel AI SDK setup lightweight and fast. Pass your layout string and JSON context to `compile_template`. The server spits back clean markup that fits right into your React or Svelte frontend components.

Strict schema safety for dynamic components

Letting an LLM write raw HTML is a security risk. This MCP setup forces the model to work with structured JSON data instead of writing code directly. The `compile_template` tool acts as a sandbox. Your agent supplies the raw data, the compiler handles the loops, and your Vercel AI SDK app gets clean, sanitized results.

Setup guide

Set up Handlebars Template Compiler 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 Handlebars Template Compiler 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 Handlebars Template Compiler transactions",
});

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

Common questions about Handlebars Template Compiler MCP in Vercel AI SDK

It stops the LLM from writing HTML directly. Instead of guessing brackets, the agent passes the data structure to `compile_template`, returning safe markup that streams cleanly.

Yes. The MCP Server executes independently, so your edge functions stay small and fast without carrying heavy template compiler dependencies.

Yes, it does. The `compile_template` tool handles nested arrays and conditional blocks natively. Your agent just feeds it the JSON payload.

The MCP tool catches the syntax error immediately. It returns a clean error message to your agent, allowing it to correct the JSON payload before retrying.

All template strings and JSON payloads are processed in an ephemeral V8 sandbox. Vinkius never logs or retains your raw marketing data or template structures.
