## Introduction

This guide walks you through connecting Imgix to Vercel AI SDK v6 using the Composio tool router. By the end, you'll have a working Imgix agent that can auto-optimize all images in this folder, overlay company logo on product photos, extract main color palette from image through natural language commands.
This guide will help you understand how to give your Vercel AI SDK agent real control over a Imgix account through Composio's Imgix MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- How to set up and configure a Vercel AI SDK agent with Imgix integration
- Using Composio's Tool Router to dynamically load and access Imgix tools
- Creating an MCP client connection using HTTP transport
- Building an interactive CLI chat interface with conversation history management
- Handling tool calls and results within the Vercel AI SDK framework

## What is Vercel AI SDK?

The Vercel AI SDK is a TypeScript library for building AI-powered applications. It provides tools for creating agents that can use external services and maintain conversation state.
Key features include:
- streamText: Core function for streaming responses with real-time tool support
- MCP Client: Built-in support for Model Context Protocol via @ai-sdk/mcp
- Step Counting: Control multi-step tool execution with stopWhen: stepCountIs()
- OpenAI Provider: Native integration with OpenAI models

## What is the Imgix MCP server, and what's possible with it?

The Imgix MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Imgix account. It provides structured and secure access to your image library, so your agent can perform actions like optimizing images, applying overlays, adjusting visual properties, and extracting color palettes on your behalf.
- Real-time image optimization: Ask your agent to automatically compress, enhance, or format images for faster delivery and better quality using Imgix's auto optimization tools.
- Dynamic overlays and blending: Direct the agent to blend images, text, or solid colors over your base images—perfect for watermarks, banners, or creative composites.
- Precision image adjustments: Have your agent modify image brightness, contrast, and border settings to meet your design and branding needs instantly.
- Extract and analyze color palettes: Let your agent pull color palettes from any image, making it easy to generate theme colors or analyze brand consistency.
- Fine-tune overlay positioning: Control exactly where overlays appear on your images by specifying alignment and pixel-level positioning through your agent.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `IMGIX_ADD_ASSET_FROM_ORIGIN` | IMGIX_ADD_ASSET_FROM_ORIGIN | Tool to queue a path from your origin to be added to the Asset Manager. Imports the asset metadata without uploading the asset itself. Use when you need to register an existing origin-hosted file with imgix. |
| `IMGIX_AUTO` | Imgix Auto Optimization | Apply automatic image optimizations using imgix's auto parameter. Use this tool to automatically optimize images for web delivery. Common use cases: - Reduce file sizes with 'compress' for faster page loads - Auto-select modern formats (AVIF/WebP) with 'format' based on browser support - Enhance image quality with 'enhance' (adjusts brightness, contrast, saturation) - Remove red-eye from portrait photos with 'redeye' Multiple options can be combined (e.g., ['compress', 'format']) for cumulative optimizations. The 'true' option is a convenient shorthand that applies 'enhance' automatically. Note: This tool works with the imgix Rendering API and requires a valid imgix source domain. For testing, use 'assets.imgix.net' with paths like 'examples/kingfisher.jpg'. |
| `IMGIX_BLEND` | Blend Overlay | Tool to overlay an image, text, or color onto a base image using imgix blending parameters. Use after specifying the base image URL and blend parameters to composite layers. |
| `IMGIX_BLEND_ALIGN` | Imgix Blend Align | Tool to align the overlay relative to the base image when blending. Use after constructing a base Imgix URL to specify horizontal and vertical alignment (e.g., 'left,top'). |
| `IMGIX_BLEND_COLOR` | Blend Color Over Image | Tool to blend a solid color over an image using CSS keyword or hex. Use when you need to apply color overlay transformations to an existing image URL. |
| `IMGIX_BLEND_X` | Imgix Blend X Position | Position an overlay image horizontally on a base image using imgix's blend-x parameter. Use this tool when you need to place an overlay (image or color) at a specific horizontal offset from the left edge of the base image. This is useful for creating watermarks, badges, or composite images where precise positioning is required. Note: The blend-x parameter only affects image overlays. Color overlays always cover the entire image regardless of this setting. |
| `IMGIX_BORDER` | Draw Image Border | Tool to draw a border around an image. Use when you need to overlay a border without resizing. |
| `IMGIX_BRI` | Adjust Image Brightness | Tool to adjust image brightness. Use when you need to modify an image's brightness level (−100 to 100) by supplying your source domain and asset path. |
| `IMGIX_CANCEL_UPLOAD_SESSION` | IMGIX_CANCEL_UPLOAD_SESSION | Tool to cancel an Imgix Asset Manager upload session. Use when you need to abort an in-progress or abandoned upload flow and clean up the session. |
| `IMGIX_CH` | IMGIX_CH | Tool to opt in to Client Hints. Use when you want Imgix URLs to adapt based on browser headers (Width, DPR, Save-Data). |
| `IMGIX_CLOSE_UPLOAD_SESSION` | IMGIX_CLOSE_UPLOAD_SESSION | Tool to close an Imgix Asset Manager upload session after the client uploads to the presigned URL. Use after uploading a file to expedite asset processing. Closing is strongly recommended by imgix. |
| `IMGIX_CON` | Adjust Image Contrast | Tool to adjust image contrast. Use when you need to modify an image's contrast level (−100 to 100). |
| `IMGIX_CREATE_IMGIX_SOURCE` | IMGIX_CREATE_IMGIX_SOURCE | Tool to create and deploy a new imgix Source. Use when you need to add a new image source with deployment configuration for S3, Web Folder, Web Proxy, GCS, Azure, or S3-compatible storage. Requires source name and deployment details with type-specific credentials and settings. |
| `IMGIX_CREATE_UPLOAD_SESSION` | IMGIX_CREATE_UPLOAD_SESSION | Tool to create an Imgix Asset Manager upload session and return a presigned URL for client-side upload. Use when you need to upload a new image to a storage-backed imgix Source without requiring external hosting. Client performs HTTP PUT of file bytes to the presigned URL, then calls IMGIX_CLOSE_UPLOAD_SESSION to finalize. |
| `IMGIX_CS` | IMGIX_CS | Tool to set or strip output color space/profile on an Imgix image. Use when optimizing compatibility and file size (e.g., cs=strip for smaller metadata). |
| `IMGIX_DL` | IMGIX_DL | Download an asset from an Imgix source with optional custom filename. Use this tool when you need to: - Download images or assets from an Imgix CDN source - Force a specific download filename (via 'dl' parameter) - Download assets with special character filenames (via 'dl64' parameter) The asset is fetched from the Imgix CDN and returned as a downloadable file reference. If neither 'dl' nor 'dl64' is specified, the original filename from the path is used. |
| `IMGIX_DPI` | Adjust Image DPI | Tool to embed DPI (dots-per-inch) metadata for print output on an Imgix-rendered image. Use when preparing images for print to set accurate DPI. Supports JPEG and PNG only. |
| `IMGIX_DPR` | Set Device Pixel Ratio | Tool to set device pixel ratio for an Imgix image. Use when rendering at specific display densities to ensure correct sharpness. Example: 'dpr=2&w=500&h=300' doubles resolution relative to dimensions. |
| `IMGIX_EXPIRES` | Imgix URL Expiration | Tool to append an expiration parameter to an Imgix URL so it returns 404 after a given time. Use when you want the image URL to stop serving beyond a specific UNIX timestamp. |
| `IMGIX_FIT` | IMGIX_FIT | Tool to control how an image fits target dimensions after resizing. Use when specifying width, height, and fit behavior. |
| `IMGIX_FM` | IMGIX_FM | Tool to choose output file format for the rendered asset. Use after specifying the asset path when you need to convert its format. |
| `IMGIX_FORCE_ASPECT_RATIO` | Force Aspect Ratio | Tool to force a target aspect ratio on an Imgix image. Use when a specific W:H frame is needed after choosing fit=crop or fit=fill. Example: 'ar=16:9&fit=crop&w=800' yields a 16:9, 800px-wide URL. |
| `IMGIX_GET_SOURCE` | IMGIX_GET_SOURCE | Tool to retrieve details for a single imgix Source by its ID. Returns the source configuration including deployment status, type, and settings. |
| `IMGIX_GET_UPLOAD_SESSION_STATUS` | IMGIX_GET_UPLOAD_SESSION_STATUS | Tool to retrieve the status of an Imgix Asset Manager upload session. Use when you need to check the current state (PENDING/CLOSED/COMPLETE/CANCELED) of an upload session for polling or verification after client PUT and/or after closing. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Imgix MCP server is an implementation of the Model Context Protocol that connects your AI agent to Imgix. It provides structured and secure access so your agent can perform Imgix operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before you begin, make sure you have:
- Node.js and npm installed
- A Composio account with API key
- An OpenAI API key

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Navigate to your API settings and generate a new API key.
- Store this key securely as you'll need it for authentication.

### 2. Install required dependencies

First, install the necessary packages for your project.
What you're installing:
- @ai-sdk/openai: Vercel AI SDK's OpenAI provider
- @ai-sdk/mcp: MCP client for Vercel AI SDK
- @composio/core: Composio SDK for tool integration
- ai: Core Vercel AI SDK
- dotenv: Environment variable management
```bash
npm install @ai-sdk/openai @ai-sdk/mcp @composio/core ai dotenv
```

### 3. Set up environment variables

Create a .env file in your project root.
What's needed:
- OPENAI_API_KEY: Your OpenAI API key for GPT model access
- COMPOSIO_API_KEY: Your Composio API key for tool access
- COMPOSIO_USER_ID: A unique identifier for the user session
```bash
OPENAI_API_KEY=your_openai_api_key_here
COMPOSIO_API_KEY=your_composio_api_key_here
COMPOSIO_USER_ID=your_user_id_here
```

### 4. Import required modules and validate environment

What's happening:
- We're importing all necessary libraries including Vercel AI SDK's OpenAI provider and Composio
- The dotenv/config import automatically loads environment variables
- The MCP client import enables connection to Composio's tool server
```typescript
import "dotenv/config";
import { openai } from "@ai-sdk/openai";
import { Composio } from "@composio/core";
import * as readline from "readline";
import { streamText, type ModelMessage, stepCountIs } from "ai";
import { createMCPClient } from "@ai-sdk/mcp";

const composioAPIKey = process.env.COMPOSIO_API_KEY;
const composioUserID = process.env.COMPOSIO_USER_ID;

if (!process.env.OPENAI_API_KEY) throw new Error("OPENAI_API_KEY is not set");
if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set");
if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set");

const composio = new Composio({
  apiKey: composioAPIKey,
});
```

### 5. Create Tool Router session and initialize MCP client

What's happening:
- We're creating a Tool Router session that gives your agent access to Imgix tools
- The create method takes the user ID and specifies which toolkits should be available
- The returned mcp object contains the URL and authentication headers needed to connect to the MCP server
- This session provides access to all Imgix-related tools through the MCP protocol
```typescript
async function main() {
  // Create a tool router session for the user
  const session = await composio.create(composioUserID!, {
    toolkits: ["imgix"],
  });

  const mcpUrl = session.mcp.url;
```

### 6. Connect to MCP server and retrieve tools

What's happening:
- We're creating an MCP client that connects to our Composio Tool Router session via HTTP
- The mcp.url provides the endpoint, and mcp.headers contains authentication credentials
- The type: "http" is important - Composio requires HTTP transport
- tools() retrieves all available Imgix tools that the agent can use
```typescript
const mcpClient = await createMCPClient({
  transport: {
    type: "http",
    url: mcpUrl,
    headers: session.mcp.headers, // Authentication headers for the Composio MCP server
  },
});

const tools = await mcpClient.tools();
```

### 7. Initialize conversation and CLI interface

What's happening:
- We initialize an empty messages array to maintain conversation history
- A readline interface is created to accept user input from the command line
- Instructions are displayed to guide the user on how to interact with the agent
```typescript
let messages: ModelMessage[] = [];

console.log("Chat started! Type 'exit' or 'quit' to end the conversation.\n");
console.log(
  "Ask any questions related to imgix, like summarize my last 5 emails, send an email, etc... :)))\n",
);

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  prompt: "> ",
});

rl.prompt();
```

### 8. Handle user input and stream responses with real-time tool feedback

What's happening:
- We use streamText instead of generateText to stream responses in real-time
- toolChoice: "auto" allows the model to decide when to use Imgix tools
- stopWhen: stepCountIs(10) allows up to 10 steps for complex multi-tool operations
- onStepFinish callback displays which tools are being used in real-time
- We iterate through the text stream to create a typewriter effect as the agent responds
- The complete response is added to conversation history to maintain context
- Errors are caught and displayed with helpful retry suggestions
```typescript
rl.on("line", async (userInput: string) => {
  const trimmedInput = userInput.trim();

  if (["exit", "quit", "bye"].includes(trimmedInput.toLowerCase())) {
    console.log("\nGoodbye!");
    rl.close();
    process.exit(0);
  }

  if (!trimmedInput) {
    rl.prompt();
    return;
  }

  messages.push({ role: "user", content: trimmedInput });
  console.log("\nAgent is thinking...\n");

  try {
    const stream = streamText({
      model: openai("gpt-5"),
      messages,
      tools,
      toolChoice: "auto",
      stopWhen: stepCountIs(10),
      onStepFinish: (step) => {
        for (const toolCall of step.toolCalls) {
          console.log(`[Using tool: ${toolCall.toolName}]`);
          }
          if (step.toolCalls.length > 0) {
            console.log(""); // Add space after tool calls
          }
        },
      });

      for await (const chunk of stream.textStream) {
        process.stdout.write(chunk);
      }

      console.log("\n\n---\n");

      // Get final result for message history
      const response = await stream.response;
      if (response?.messages?.length) {
        messages.push(...response.messages);
      }
    } catch (error) {
      console.error("\nAn error occurred while talking to the agent:");
      console.error(error);
      console.log(
        "\nYou can try again or restart the app if it keeps happening.\n",
      );
    } finally {
      rl.prompt();
    }
  });

  rl.on("close", async () => {
    await mcpClient.close();
    console.log("\n👋 Session ended.");
    process.exit(0);
  });
}

main().catch((err) => {
  console.error("Fatal error:", err);
  process.exit(1);
});
```

## Conclusion

You've successfully built a Imgix agent using the Vercel AI SDK with streaming capabilities! This implementation provides a powerful foundation for building AI applications with natural language interfaces and real-time feedback.
Key features of this implementation:
- Real-time streaming responses for a better user experience with typewriter effect
- Live tool execution feedback showing which tools are being used as the agent works
- Dynamic tool loading through Composio's Tool Router with secure authentication
- Multi-step tool execution with configurable step limits (up to 10 steps)
- Comprehensive error handling for robust agent execution
- Conversation history maintenance for context-aware responses
You can extend this further by adding custom error handling, implementing specific business logic, or integrating additional Composio toolkits to create multi-app workflows.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Imgix MCP?

With a standalone Imgix MCP server, the agents and LLMs can only access a fixed set of Imgix tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Imgix and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Vercel AI SDK v6?

Yes, you can. Vercel AI SDK v6 fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Imgix tools.

### Can I manage the permissions and scopes for Imgix while using Tool Router?

Yes, absolutely. You can configure which Imgix scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Imgix data and credentials are handled as safely as possible.
