## Introduction

This guide walks you through connecting Hotspotsystem to LangChain using the Composio tool router. By the end, you'll have a working Hotspotsystem agent that can list all customers at main street location, generate a single-use voucher for lobby, list paid transactions for downtown hotspot through natural language commands.
This guide will help you understand how to give your LangChain agent real control over a Hotspotsystem account through Composio's Hotspotsystem 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 Hotspotsystem MCP server, and what's possible with it?

The Hotspotsystem MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Hotspotsystem account. It provides structured and secure access to your Wi-Fi hotspot management platform, so your agent can perform actions like listing customers, generating access vouchers, monitoring transactions, and managing subscribers across your locations.
- Customer and subscriber management: Instantly list all customers or newsletter subscribers, or filter them by specific hotspot locations for targeted communications or support.
- On-demand voucher generation: Have your agent create single-use access vouchers for guests or events—automatically and only when there are enough credits.
- Location and asset visibility: Retrieve and review all your registered hotspot locations, making it easy to audit or manage distributed sites and devices.
- Transaction monitoring and reporting: List MAC-based or paid transactions by location, enabling your agent to provide real-time analytics or billing support for your hotspots.
- API health checks and diagnostics: Use the agent to ping the Hotspotsystem API for connectivity checks, ensuring your integrations and automations run smoothly.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `HOTSPOTSYSTEM_CUSTOMERS_LIST` | List Customers | Lists all customers in the HotspotSystem account with optional filtering. Use this tool to: - Retrieve all customers with their details (name, email, contact info, registration date, etc.) - Paginate through large customer lists using limit and offset parameters - Sort customers by any field in ascending or descending order - Filter response to only include specific fields to reduce payload size Returns metadata with total customer count and an array of customer objects. |
| `HOTSPOTSYSTEM_CUSTOMERS_LIST_BY_LOCATION` | List Customers by Location | Lists all customers associated with a specific HotspotSystem location. Use this tool to: - Retrieve customer details (name, email, contact info, registration date) for a specific location - Paginate through large customer lists using limit and offset parameters - Sort customers by any field (prepend '-' for descending order, e.g., '-registered_at') - Filter response to include only specific fields to reduce payload size - Query customers at different locations by location ID Returns metadata with total customer count and an array of customer objects. Note: Empty results (total_count: 0) indicate no customers are registered at the specified location. |
| `HOTSPOTSYSTEM_GENERATE_VOUCHER_V1` | Generate Voucher (v1) | Generates an access voucher code on-demand for a specific location. This action creates a single-use voucher that can be used for hotspot access. The voucher is generated against available voucher credits in the specified location. Use this when you need to provide immediate access codes to users. Note: Requires an active location with available voucher credits (use the List Locations action first to get valid location_id values). |
| `HOTSPOTSYSTEM_GET_LOCATIONS_OPTIONS` | Get Locations Options | Tool to get simplified list of locations as dropdown options. Returns only id/name pairs for each location. Use when you need location options for selection menus or dropdowns. |
| `HOTSPOTSYSTEM_GET_ME` | Get Me | Tool to verify the resource owner's credentials and retrieve authenticated user information. Use when you need to confirm authentication status or get the current user's ID and operator name. |
| `HOTSPOTSYSTEM_LIST_PAID_TRANSACTIONS` | List Paid Transactions | Tool to list paid transactions globally across all locations. Use when you need to retrieve all paid transaction records with optional pagination and sorting. |
| `HOTSPOTSYSTEM_LOCATIONS_LIST` | List Locations | Tool to list the resource owner's locations. Use when you need to retrieve locations with optional filtering, sorting, or pagination. |
| `HOTSPOTSYSTEM_MISC_PING` | Misc Ping | Tool to perform health check against the HotspotSystem API. Use when verifying connectivity and availability. |
| `HOTSPOTSYSTEM_SUBSCRIBERS_LIST` | List Subscribers | List newsletter subscribers across all locations with optional filtering, sorting, and pagination. Returns subscriber information including contact details (name, email, phone, address) and social network data (Facebook, Google, etc.). Supports field selection to retrieve only needed properties, sorting by any field (ascending or descending), and pagination with limit/offset for large result sets. Use this tool when you need to: - Retrieve all subscribers for the account - Filter subscribers by specific fields - Sort subscribers by registration date, name, email, etc. - Paginate through large subscriber lists |
| `HOTSPOTSYSTEM_SUBSCRIBERS_LIST_BY_LOCATION` | List Subscribers by Location | Tool to list subscribers by location. Use when you need to retrieve subscribers for a specific location with optional field selection, sorting, and pagination. |

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

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

url = session.mcp.url
```

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

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

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

No description provided.
```python
client = MultiServerMCPClient({
    "hotspotsystem-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({
    "hotspotsystem-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 Hotspotsystem 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 Hotspotsystem 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 Hotspotsystem MCP?

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

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

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