## Introduction

This guide walks you through connecting Shortpixel to LangChain using the Composio tool router. By the end, you'll have a working Shortpixel agent that can check your remaining shortpixel credits, purge all images from site storage, monitor api key usage status through natural language commands.
This guide will help you understand how to give your LangChain agent real control over a Shortpixel account through Composio's Shortpixel MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## What is LangChain?

LangChain is a framework for developing applications powered by language models. It provides tools and abstractions for building agents that can reason, use tools, and maintain conversation context.
Key features include:
- Agent Framework: Build agents that can use tools and make decisions
- MCP Integration: Connect to external services through Model Context Protocol adapters
- Memory Management: Maintain conversation history across interactions
- Multi-Provider Support: Works with OpenAI, Anthropic, and other LLM providers

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

The Shortpixel MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your ShortPixel account. It provides structured and secure access to your image optimization tools, so your agent can perform actions like monitoring API usage, purging storage, and managing your ShortPixel resources on your behalf.
- API status monitoring: Instantly check your API key status, including available image optimization credits, so you never run out unexpectedly.
- Bulk storage purging: Direct your agent to purge all files stored on ShortPixel servers for a domain, making large-scale cleanups quick and hassle-free.
- Account usage visibility: Let your agent retrieve up-to-date usage metrics before initiating new optimization tasks or campaigns.
- Automated maintenance workflows: Schedule regular storage purges or status checks, keeping your ShortPixel account organized with minimal manual effort.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `SHORTPIXEL_ADD_CDN_DOMAIN` | Add CDN Domain | Tool to add a new domain to the ShortPixel CDN system and associate it with your API key. Use when you need to register a domain for CDN services. If the domain already exists without a user, it will be associated with your API key. |
| `SHORTPIXEL_BULK_PURGE_STORAGE` | Bulk Purge ShortPixel Storage | Tool to purge all files stored on ShortPixel storage servers for a domain. Use when you need to remove all stored files for a site in bulk. |
| `SHORTPIXEL_CHECK_IMAGE_STATUS` | Check Image Status | Tool to check the optimization status of an image being processed by ShortPixel. Returns current status of queued images including URLs and size information. |
| `SHORTPIXEL_CLEAN_UP_IMAGE` | Clean Up Image | Tool to remove images from the processing queue. Use when you need to optimize another image with the same URL but different contents within the next hour. |
| `SHORTPIXEL_GET_ADAPTIVE_IMAGE_CDN` | Get Adaptive Image via CDN | Tool to optimize images on-the-fly via ShortPixel CDN. Transform images by URL with parameters for width, height, cropping, quality, and format conversion. Returns the optimized image directly without CDN caching. |
| `SHORTPIXEL_GET_API_STATUS` | Get API Status | Tool to retrieve the current status of your API key, including available credits. Use when you need to monitor your account usage before making additional API calls. |
| `SHORTPIXEL_GET_CDN_USAGE` | Get CDN Usage Statistics | Tool to retrieve detailed CDN usage statistics for a domain including traffic, API calls, monthly quota, remaining credits, and historical usage breakdown by date. Use when you need to monitor CDN consumption or check quota status. |
| `SHORTPIXEL_OPTIMIZE_IMAGES_BY_URL` | Optimize Images by URL | Tool to optimize images by providing their URLs. Supports batch processing of up to 100 URLs per request with options for lossy, glossy, or lossless compression, resizing, format conversion (WebP/AVIF), and background removal. Use when you need to compress and optimize images accessible online. |
| `SHORTPIXEL_READ_CDN_DOMAIN` | Read CDN Domain Status | Tool to check the status of a domain and its CDN quota on ShortPixel. Returns a status code indicating credit availability. Use when you need to verify domain accessibility and quota status. |
| `SHORTPIXEL_REVOKE_CDN_DOMAIN` | Revoke CDN Domain | Tool to revoke a domain association from ShortPixel CDN. Only works if the API key belongs to the current domain owner. Use when you need to remove the association between a domain and the user account. |
| `SHORTPIXEL_SET_CDN_DOMAIN` | Set CDN Domain | Tool to associate an API key with an existing domain. Unlike add-domain, this does not create a new domain - it only associates a user ID if not already associated. Use when you need to claim unassociated domains. |
| `SHORTPIXEL_UPLOAD_AND_OPTIMIZE_IMAGES` | Upload and Optimize Images | Tool to upload and optimize images that are not accessible online. Uses multipart form data to upload files directly and applies optimization parameters like compression type, resize options, and format conversion. |

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

The Shortpixel MCP server is an implementation of the Model Context Protocol that connects your AI agent to Shortpixel. It provides structured and secure access so your agent can perform Shortpixel 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

No description provided.

### 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 dependencies

No description provided.
```python
pip install composio-langchain langchain-mcp-adapters langchain python-dotenv
```

```typescript
npm install @composio/langchain @langchain/core @langchain/openai @langchain/mcp-adapters dotenv
```

### 3. Set up environment variables

Create a .env file in your project root.
What's happening:
- COMPOSIO_API_KEY authenticates your requests to Composio's API
- COMPOSIO_USER_ID identifies the user for session management
- OPENAI_API_KEY enables access to OpenAI's language models
```bash
COMPOSIO_API_KEY=your_composio_api_key_here
COMPOSIO_USER_ID=your_composio_user_id_here
OPENAI_API_KEY=your_openai_api_key_here
```

### 4. Import dependencies

No description provided.
```python
from langchain_mcp_adapters.client import MultiServerMCPClient
from langchain.agents import create_agent
from dotenv import load_dotenv
from composio import Composio
import asyncio
import os

load_dotenv()
```

```typescript
import { Composio } from '@composio/core';
import { LangchainProvider } from '@composio/langchain';
import { MultiServerMCPClient } from "@langchain/mcp-adapters";
import { createAgent } from "langchain";
import * as readline from 'readline';
import 'dotenv/config';

dotenv.config();
```

### 5. Initialize Composio client

What's happening:
- We're loading the COMPOSIO_API_KEY from environment variables and validating it exists
- Creating a Composio instance that will manage our connection to Shortpixel tools
- Validating that COMPOSIO_USER_ID is also set before proceeding
```python
async def main():
    composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY"))

    if not os.getenv("COMPOSIO_API_KEY"):
        raise ValueError("COMPOSIO_API_KEY is not set")
    if not os.getenv("COMPOSIO_USER_ID"):
        raise ValueError("COMPOSIO_USER_ID is not set")
```

```typescript
const composioApiKey = process.env.COMPOSIO_API_KEY;
const userId = process.env.COMPOSIO_USER_ID;

if (!composioApiKey) throw new Error('COMPOSIO_API_KEY is not set');
if (!userId) throw new Error('COMPOSIO_USER_ID is not set');

async function main() {
    const composio = new Composio({
        apiKey: composioApiKey as string,
        provider: new LangchainProvider()
    });
```

### 6. Create a Tool Router session

What's happening:
- We're creating a Tool Router session that gives your agent access to Shortpixel tools
- The create method takes the user ID and specifies which toolkits should be available
- The returned session.mcp.url is the MCP server URL that your agent will use
- This approach allows the agent to dynamically load and use Shortpixel tools as needed
```python
# Create Tool Router session for Shortpixel
session = composio.create(
    user_id=os.getenv("COMPOSIO_USER_ID"),
    toolkits=['shortpixel']
)

url = session.mcp.url
```

```typescript
const session = await composio.create(
    userId as string,
    {
        toolkits: ['shortpixel']
    }
);

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

### 7. Configure the agent with the MCP URL

No description provided.
```python
client = MultiServerMCPClient({
    "shortpixel-agent": {
        "transport": "streamable_http",
        "url": session.mcp.url,
        "headers": {
            "x-api-key": os.getenv("COMPOSIO_API_KEY")
        }
    }
})

tools = await client.get_tools()

agent = create_agent("gpt-5", tools)
```

```typescript
const client = new MultiServerMCPClient({
    "shortpixel-agent": {
        transport: "http",
        url: url,
        headers: {
            "x-api-key": process.env.COMPOSIO_API_KEY
        }
    }
});

const tools = await client.getTools();

const agent = createAgent({ model: "gpt-5", tools });
```

### 8. Set up interactive chat interface

No description provided.
```python
conversation_history = []

print("Chat started! Type 'exit' or 'quit' to end the conversation.\n")
print("Ask any Shortpixel related question or task to the agent.\n")

while True:
    user_input = input("You: ").strip()

    if user_input.lower() in ['exit', 'quit', 'bye']:
        print("\nGoodbye!")
        break

    if not user_input:
        continue

    conversation_history.append({"role": "user", "content": user_input})
    print("\nAgent is thinking...\n")

    response = await agent.ainvoke({"messages": conversation_history})
    conversation_history = response['messages']
    final_response = response['messages'][-1].content
    print(f"Agent: {final_response}\n")
```

```typescript
let conversationHistory: any[] = [];

console.log("Chat started! Type 'exit' or 'quit' to end the conversation.\n");
console.log("Ask any Shortpixel related question or task to the agent.\n");

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

rl.prompt();

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;
    }

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

    const response = await agent.invoke({ messages: conversationHistory });
    conversationHistory = response.messages;

    const finalResponse = response.messages[response.messages.length - 1]?.content;
    console.log(`Agent: ${finalResponse}\n`);
        
        rl.prompt();
    });

    rl.on('close', () => {
        console.log('\n👋 Session ended.');
        process.exit(0);
    });
```

### 9. Run the application

## Frequently Asked Questions

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

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

### Can I use Tool Router MCP with LangChain?

Yes, you can. LangChain 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 Shortpixel tools.

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

Yes, absolutely. You can configure which Shortpixel 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 Shortpixel data and credentials are handled as safely as possible.
