How to Use the JSONBin.io MCP in Vercel AI SDK

Q: How do I connect JSONBin.io to the Vercel AI SDK?

Install @ai-sdk/mcp and use createMCPClient. Pass the HTTP transport URL, call mcpClient.tools(), and feed the results into streamText.

Q: Can the Vercel AI SDK read specific versions of JSONBin.io data?

Yes. The readbin tool accepts version parameters. Your agent can pull historical states of a bin directly into your edge function.

Q: Does JSONBin.io work with Vercel AI SDK streaming?

It works perfectly. The agent executes updatebin in the background while streamText pushes the UI updates to your React frontend.

Q: How do I organize bins for different users?

Use the createcollection tool to group bins by user ID or session. You can list them later with fetchcollectionbins.

Live State Management via MCP Server

The `create_bin` and `update_bin` tools let your Vercel AI SDK agent manage remote JSON state on the fly. When a user interacts with your frontend, the agent writes their preferences or session data directly to JSONBin.io. You don't need a heavy database for simple state. Your Next.js app streams the results back to the client while `read_bin` pulls the updated records for the next interaction.

Schema Validation on the Edge

The `create_schema` tool enforces strict data contracts before your agent writes anything. You define the shape of the data, and `add_schema_to_collection` locks it to a specific group of bins. This prevents malformed AI outputs from breaking your React components. If the agent tries to push bad data, the server rejects it before it hits your production UI.

XL Bins for Heavy Payloads

The `create_xl_bin` tool handles payloads up to 10MB for accounts with Early Access. Your agent can store massive arrays of generated text, image metadata, or complex nested objects without hitting standard limits. When your frontend needs that data, `read_xl_bin` pulls it down. You can filter the response using JSON Path to grab exactly what your UI needs right now.

Setup guide

Set up JSONBin.io 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 JSONBin.io 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 JSONBin.io transactions",
});

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