## Introduction

This guide walks you through connecting Codereadr to LangChain using the Composio tool router. By the end, you'll have a working Codereadr agent that can create a new barcode scanning service, configure survey questions after each scan, enable kiosk mode for unattended device through natural language commands.
This guide will help you understand how to give your LangChain agent real control over a Codereadr account through Composio's Codereadr 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 Codereadr MCP server, and what's possible with it?

The Codereadr MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Codereadr account. It provides structured and secure access to your data collection and barcode scanning workflows, so your agent can create services, configure scan workflows, manage databases, and automate data collection processes for you.
- Automated service and workflow setup: Let your agent create new CodeREADr services and configure custom workflows for scanning, picking, delivery, and receiving tasks.
- Custom data collection form creation: Easily set up or modify data capture forms by adding or deleting custom questions after each scan.
- Real-time scan integration: Configure Direct Scan URLs, postback endpoints, or Google Sheets connectors to forward scan results instantly to your desired platforms.
- Device and database management: Direct your agent to delete devices or entire databases when they are no longer needed, streamlining your data environment.
- Kiosk and unattended scanning configuration: Enable and fine-tune Kiosk Mode for unattended or dedicated scanning stations to support high-volume operations.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CODEREADR_COLLECT_DATA_WITH_QUESTIONS` | Collect Data With Questions | Create and attach custom questions to a CodeREADr service for data collection after scans. Use this to configure forms that collect additional information from users after each barcode scan. Requires a valid service ID from CODEREADR_RETRIEVE_SERVICES or CODEREADR_CREATE_SERVICE. |
| `CODEREADR_CONFIGURE_CONNECTOR` | Configure CodeREADr Connector | Helper to guide configuring the CodeREADr Connector for Google Sheets. There is no public API to programmatically create connector configurations. This tool validates your API connectivity (optional) and returns clear steps to proceed via the Google Sheets Add-on UI: https://www.codereadr.com/knowledgebase/codereadr-connector-add-on/ |
| `CODEREADR_CREATE_SERVICE` | Create CodeREADr Service | Creates a new CodeREADr service (barcode scanning workflow configuration). A service defines how barcode scans are processed - whether they're simply recorded, validated against a database, forwarded to an external URL, or display web content. Each validation_method type has different required parameters: 'database'/'ondevicedatabase' require database_id, 'postback' requires postback_url, 'webview' requires description (URL/HTML). |
| `CODEREADR_DELETE_DATABASE` | Delete CodeREADr Database | Delete a CodeREADr validation database by its ID. This permanently removes the database and all its barcode values. Use with caution. Note: A database cannot be deleted if it is currently linked to one or more services. You must unlink those services from the database first. Example: "Delete database with ID 1340798" |
| `CODEREADR_DELETE_DEVICE` | Delete Device | Tool to delete a device from CodeREADr. Uses the CodeREADr legacy API with section=devices and action=delete parameters. Note: Device deletion may have limited support in the CodeREADr API - only 'retrieve' and 'update' actions are officially documented for devices. |
| `CODEREADR_DELETE_QUESTION` | Delete Custom Question | Permanently deletes one or more custom questions from your CodeREADr account. Questions are used to collect additional data after scans. Once deleted, the question and all associated answer options are removed. This action cannot be undone. |
| `CODEREADR_DELETE_SERVICE` | Delete CodeREADr Service | Delete a CodeREADr service by its numeric ID. Use this to permanently remove a service/workflow configuration from your account. Note: This is a destructive action and cannot be undone. You can delete a single service, multiple services (comma-separated IDs), or all services. Example: "Delete service with ID 12345" |
| `CODEREADR_DELETE_USER` | Delete CodeREADr User | Deletes an existing user account from CodeREADr. Uses the CodeREADr legacy API endpoint (POST /api/ with section=users, action=delete). The user_id parameter can be a single ID, comma-separated list of IDs, or 'all'. Note: You cannot delete the account owner's app-user. The API will return an error if an invalid user_id is provided. |
| `CODEREADR_GENERATE_SCAN_LINK` | Generate Scan Link | Generates a CodeREADr scan link URI that opens the CodeREADr mobile app with a pre-filled scan value. Use this tool when you need to create clickable links that launch the CodeREADr scanner with a specific barcode, QR code, or identifier already entered. |
| `CODEREADR_LIST_SUPPORTED_BARCODE_TYPES` | List Supported Barcode Types | Lists barcode symbologies supported by CodeREADr for scanning. Returns 1D barcodes (Code 39, Code 128, EAN, UPC, Codabar, etc.), 2D barcodes (QR Code, Data Matrix, PDF-417, Aztec, etc.), and specialized formats. Use this to verify if a specific barcode type is supported before scanning. |
| `CODEREADR_RETRIEVE_DATABASES` | Retrieve CodeREADr Databases | Retrieves all validation databases configured in your CodeREADr account. Use this to list databases for barcode validation, see their IDs, names, item counts, and which services they're linked to. |
| `CODEREADR_RETRIEVE_DEVICES` | Retrieve Devices | Retrieve a list of devices registered to your CodeREADr account. This tool fetches information about devices linked to your account, including device IDs, UDIDs, names, and creation timestamps. Use this to monitor which devices have access to your CodeREADr services. |
| `CODEREADR_RETRIEVE_SCANS` | Retrieve Scan Records | Retrieve scan records from your CodeREADr account. Scans are the core data collected by CodeREADr when users scan barcodes using the mobile app. Each scan record includes the barcode value, timestamp, device info, validation status, and any collected responses. Use filters to narrow down results by service, user, device, date range, or status. Returns scan records in batches. Use limit and offset parameters for pagination. |
| `CODEREADR_RETRIEVE_SERVICES` | Retrieve CodeREADr Services | Retrieve configured services from your CodeREADr account. Services are the core organizational units in CodeREADr that define how barcode scans are validated and processed. Use this action to list all services or retrieve specific services by ID. |
| `CODEREADR_UPDATE_QUESTION` | Update CodeREADr Question | Add answer options to an existing CodeREADr question. Use this to add selectable answers for checkbox, dropdown, or option-type questions. The CodeREADr API does not support updating question text - to change text, delete and recreate the question. |
| `CODEREADR_UPDATE_SERVICE` | Update CodeREADr Service | Update an existing CodeREADr service configuration. Use this action to modify settings of a service by its ID. Only specified fields will be updated - omitted fields retain their current values. Common use cases: - Renaming a service - Changing postback/webhook URL - Enabling/disabling GPS tracking - Modifying duplicate scan handling - Setting time restrictions for service availability |

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

The Codereadr MCP server is an implementation of the Model Context Protocol that connects your AI agent to Codereadr. It provides structured and secure access so your agent can perform Codereadr 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 Codereadr 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 Codereadr 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 Codereadr tools as needed
```python
# Create Tool Router session for Codereadr
session = composio.create(
    user_id=os.getenv("COMPOSIO_USER_ID"),
    toolkits=['codereadr']
)

url = session.mcp.url
```

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

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

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

No description provided.
```python
client = MultiServerMCPClient({
    "codereadr-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({
    "codereadr-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 Codereadr 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 Codereadr 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

No description provided.
```python
if __name__ == "__main__":
    asyncio.run(main())
```

```typescript

## Conclusion

You've successfully built a LangChain agent that can interact with Codereadr through Composio's Tool Router.
Key features of this implementation:
- Dynamic tool loading through Composio's Tool Router
- Conversation history maintenance for context-aware responses
- Async Python provides clean, efficient execution of agent workflows
You can extend this further by adding 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 Codereadr MCP?

With a standalone Codereadr MCP server, the agents and LLMs can only access a fixed set of Codereadr tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Codereadr 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 Codereadr tools.

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

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