## Introduction

This guide walks you through connecting Desktime to LangChain using the Composio tool router. By the end, you'll have a working Desktime agent that can list all active projects with tasks, get today's time tracked for each employee, start timing work on 'client website redesign' through natural language commands.
This guide will help you understand how to give your LangChain agent real control over a Desktime account through Composio's Desktime 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:
- Get and set up your OpenAI and Composio API keys
- Connect your Desktime project to Composio
- Create a Tool Router MCP session for Desktime
- Initialize an MCP client and retrieve Desktime tools
- Build a LangChain agent that can interact with Desktime
- Set up an interactive chat interface for testing

## 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 Desktime MCP server, and what's possible with it?

The Desktime MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Desktime account. It provides structured and secure access to your time tracking, project management, and productivity data, so your agent can perform actions like tracking work hours, managing projects, analyzing employee productivity, and reporting on team activities on your behalf.
- Automated project and task management: Create new projects, assign optional starter tasks, and retrieve a comprehensive list of active company projects for streamlined organization.
- Employee and company insights: Instantly fetch detailed company account info, list all employees with their roles and statuses, and access individual employee data for better workforce visibility.
- Time tracking control: Start or stop tracking work on specific projects and tasks, enabling hands-free, accurate logging of work sessions and project contributions.
- Productivity and app usage analysis: Retrieve employee project assignments and application usage data to monitor work habits and identify productivity trends across your team.
- API health and connectivity checks: Use built-in API ping tools to verify Desktime API availability and ensure uninterrupted agent operations.

## Supported Tools

| Tool slug | Name | Description |

| `DESKTIME_GET_ACCOUNT_DETAILS` | Get Account Details | Retrieves company account configuration including work schedule and timezone settings. This action fetches company-level information such as company name, work hours (start/end times), work duration, working days configuration, time tracking hours, and timezone. No parameters are required. This is useful for understanding the company's work schedule configuration and timezone settings. |
| `DESKTIME_GET_ALL_COMPANY_EMPLOYEES` | Get All Company Employees | Tool to list all employees in the company, including their roles and statuses. Use after confirming valid credentials to fetch the organization’s roster. |
| `DESKTIME_GET_EMPLOYEE` | Get Employee | Tool to retrieve information about a single employee including user info, work settings, and tracking data for a specific date. Use when you need detailed information for one employee. Returns data for the currently logged-in user if no employee ID is specified. |
| `DESKTIME_GET_EMPLOYEE_APPS` | Get Employee Apps | Retrieves employee tracking data including tracked apps for a specific date. Returns data for the currently logged-in user if no employee ID is specified. Use this action to view detailed application usage and productivity data for an employee. |
| `DESKTIME_GET_EMPLOYEE_PROJECTS` | Get Employee Projects | Retrieves comprehensive employee project tracking data including project assignments, time tracking metrics, work hours, and productivity statistics for a specific employee and date. Returns detailed information about: - Employee profile (ID, name, email, group) - Time tracking metrics (online time, productive time, efficiency) - Work schedule (work start/end times, timezone) - Active project details (current project and task being worked on) - Projects list (all projects tracked on the specified date with durations) - Employee status indicators (online, arrived, left, late) Use this action when you need to: - View an employee's project assignments and tracking data - Check time spent on specific projects by an employee - Monitor employee productivity and work hours - Retrieve historical project tracking data for a specific date Both parameters are optional - defaults to current API-key user and today's date. |
| `DESKTIME_GET_EMPLOYEE_PROJECTS_AND_APPS` | Get Employee Basic Data | Retrieve an employee's basic information and daily tracking statistics from DeskTime. Returns employee profile data, work hours, productivity metrics, attendance status, and currently active project. Use this when you need employee time tracking data for a specific date (defaults to today). Note: For detailed project/app usage breakdowns, use the dedicated Get Employee Projects action. |
| `DESKTIME_GET_PROJECTS_LIST` | Get Projects List | Tool to retrieve all active projects for the company, including related tasks. Use when you need projects overview after authentication. |
| `DESKTIME_PING_REQUEST` | Ping DeskTime API | Tool to check the API's availability and confirm the service is operational. Use when you need to verify that the DeskTime API is reachable and responsive. |
| `DESKTIME_START_PROJECT_TASK` | Start Project Task | Starts time tracking for a specified project and optional task in DeskTime. This action begins recording time against the specified project. If a task name is provided, time is also tracked at the task level within that project. Both projects and tasks are created automatically if they don't already exist in the DeskTime account. Use this action when a user wants to: - Begin working on a project and track time - Start a specific task within a project - Switch time tracking to a different project or task Note: Only one project/task can be tracked at a time per user. Starting a new project automatically stops tracking on any previously active project. |
| `DESKTIME_STOP_PROJECT_TASK` | Stop Project Task | Tool to stop tracking time for a specified project and optional task. Use when you have finished work and need to record end time. |

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

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

url = session.mcp.url
```

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

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

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

No description provided.
```python
client = MultiServerMCPClient({
    "desktime-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({
    "desktime-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 Desktime 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 Desktime 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
main().catch((err) => {
    console.error('Fatal error:', err);

## Frequently Asked Questions

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

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

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

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