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 Mastra AI 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. ## Also integrate Desktime with - [OpenAI Agents SDK](https://composio.dev/toolkits/desktime/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/desktime/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/desktime/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/desktime/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/desktime/framework/codex) - [OpenClaw](https://composio.dev/toolkits/desktime/framework/openclaw) - [Hermes](https://composio.dev/toolkits/desktime/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/desktime/framework/cli) - [Google ADK](https://composio.dev/toolkits/desktime/framework/google-adk) - [LangChain](https://composio.dev/toolkits/desktime/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/desktime/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/desktime/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/desktime/framework/crew-ai) ## TL;DR Here's what you'll learn: - Set up your environment so Mastra, OpenAI, and Composio work together - Create a Tool Router session in Composio that exposes Desktime tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Desktime tool definitions and attach them as a toolset - Build a Mastra agent that can reason, call tools, and return structured results - Run an interactive CLI where you can chat with your Desktime agent ## What is Mastra AI? Mastra AI is a TypeScript framework for building AI agents with tool support. It provides a clean API for creating agents that can use external services through MCP. Key features include: - MCP Client: Built-in support for Model Context Protocol servers - Toolsets: Organize tools into logical groups - Step Callbacks: Monitor and debug agent execution - OpenAI Integration: Works with OpenAI models via @ai-sdk/openai ## 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_CREATE_PROJECT_WITH_TASK` | Create Project with Optional Task | Tool to create a new project with an optional initial task. Use when you need to set up a new DeskTime project programmatically. | | `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. | ## Supported Triggers None listed. ## 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 Before starting, make sure you have: - Node.js 18 or higher - A Composio account with an active API key - An OpenAI API key - Basic familiarity with TypeScript ### 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 need credits or a connected billing setup to use the models. - Store the key somewhere safe. Composio API Key - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Go to Settings and copy your API key. - This key lets your Mastra agent talk to Composio and reach Desktime through MCP. ### 2. Install dependencies Install the required packages. What's happening: - @composio/core is the Composio SDK for creating MCP sessions - @mastra/core provides the Agent class - @mastra/mcp is Mastra's MCP client - @ai-sdk/openai is the model wrapper for OpenAI - dotenv loads environment variables from .env ```bash npm install @composio/core @mastra/core @mastra/mcp @ai-sdk/openai 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 - COMPOSIO_USER_ID tells Composio which user this session belongs to - OPENAI_API_KEY lets the Mastra agent call OpenAI models ```bash COMPOSIO_API_KEY=your_composio_api_key_here COMPOSIO_USER_ID=your_user_id_here OPENAI_API_KEY=your_openai_api_key_here ``` ### 4. Import libraries and validate environment What's happening: - dotenv/config auto loads your .env so process.env.* is available - openai gives you a Mastra compatible model wrapper - Agent is the Mastra agent that will call tools and produce answers - MCPClient connects Mastra to your Composio MCP server - Composio is used to create a Tool Router session ```typescript import "dotenv/config"; import { openai } from "@ai-sdk/openai"; import { Agent } from "@mastra/core/agent"; import { MCPClient } from "@mastra/mcp"; import { Composio } from "@composio/core"; import * as readline from "readline"; import type { AiMessageType } from "@mastra/core/agent"; const openaiAPIKey = process.env.OPENAI_API_KEY; const composioAPIKey = process.env.COMPOSIO_API_KEY; const composioUserID = process.env.COMPOSIO_USER_ID; if (!openaiAPIKey) 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 as string, }); ``` ### 5. Create a Tool Router session for Desktime What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "desktime" for Desktime access - session.mcp.url is the MCP URL that Mastra's MCPClient will connect to ```typescript async function main() { const session = await composio.create( composioUserID as string, { toolkits: ["desktime"], }, ); const composioMCPUrl = session.mcp.url; console.log("Desktime MCP URL:", composioMCPUrl); ``` ### 6. Configure Mastra MCP client and fetch tools What's happening: - MCPClient takes an id for this client and a list of MCP servers - The headers property includes the x-api-key for authentication - getTools fetches the tool definitions exposed by the Desktime toolkit ```typescript const mcpClient = new MCPClient({ id: composioUserID as string, servers: { nasdaq: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); console.log("Fetching MCP tools from Composio..."); const composioTools = await mcpClient.getTools(); console.log("Number of tools:", Object.keys(composioTools).length); ``` ### 7. Create the Mastra agent What's happening: - Agent is the core Mastra agent - name is just an identifier for logging and debugging - instructions guide the agent to use tools instead of only answering in natural language - model uses openai("gpt-5") to configure the underlying LLM ```typescript const agent = new Agent({ name: "desktime-mastra-agent", instructions: "You are an AI agent with Desktime tools via Composio.", model: "openai/gpt-5", }); ``` ### 8. Set up interactive chat interface What's happening: - messages keeps the full conversation history in Mastra's expected format - agent.generate runs the agent with conversation history and Desktime toolsets - maxSteps limits how many tool calls the agent can take in a single run - onStepFinish is a hook that prints intermediate steps for debugging ```typescript let messages: AiMessageType[] = []; console.log("Chat started! Type 'exit' or 'quit' to end.\n"); const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: "> ", }); 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; } messages.push({ id: crypto.randomUUID(), role: "user", content: trimmedInput, }); console.log("\nAgent is thinking...\n"); try { const response = await agent.generate(messages, { toolsets: { desktime: composioTools, }, maxSteps: 8, }); const { text } = response; if (text && text.trim().length > 0) { console.log(`Agent: ${text}\n`); messages.push({ id: crypto.randomUUID(), role: "assistant", content: text, }); } } catch (error) { console.error("\nError:", error); } rl.prompt(); }); rl.on("close", async () => { console.log("\nSession ended."); await mcpClient.disconnect(); process.exit(0); }); } main().catch((err) => { console.error("Fatal error:", err); process.exit(1); }); ``` ## Complete Code ```typescript import "dotenv/config"; import { openai } from "@ai-sdk/openai"; import { Agent } from "@mastra/core/agent"; import { MCPClient } from "@mastra/mcp"; import { Composio } from "@composio/core"; import * as readline from "readline"; import type { AiMessageType } from "@mastra/core/agent"; const openaiAPIKey = process.env.OPENAI_API_KEY; const composioAPIKey = process.env.COMPOSIO_API_KEY; const composioUserID = process.env.COMPOSIO_USER_ID; if (!openaiAPIKey) 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 as string }); async function main() { const session = await composio.create(composioUserID as string, { toolkits: ["desktime"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { desktime: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "desktime-mastra-agent", instructions: "You are an AI agent with Desktime tools via Composio.", model: "openai/gpt-5", }); let messages: AiMessageType[] = []; const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: "> ", }); rl.prompt(); rl.on("line", async (input: string) => { const trimmed = input.trim(); if (["exit", "quit"].includes(trimmed.toLowerCase())) { rl.close(); return; } messages.push({ id: crypto.randomUUID(), role: "user", content: trimmed }); const { text } = await agent.generate(messages, { toolsets: { desktime: composioTools }, maxSteps: 8, }); if (text) { console.log(`Agent: ${text}\n`); messages.push({ id: crypto.randomUUID(), role: "assistant", content: text }); } rl.prompt(); }); rl.on("close", async () => { await mcpClient.disconnect(); process.exit(0); }); } main(); ``` ## Conclusion You've built a Mastra AI agent that can interact with Desktime through Composio's Tool Router. You can extend this further by: - Adding other toolkits like Gmail, Slack, or GitHub - Building a web-based chat interface around this agent - Using multiple MCP endpoints to enable cross-app workflows ## How to build Desktime MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/desktime/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/desktime/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/desktime/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/desktime/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/desktime/framework/codex) - [OpenClaw](https://composio.dev/toolkits/desktime/framework/openclaw) - [Hermes](https://composio.dev/toolkits/desktime/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/desktime/framework/cli) - [Google ADK](https://composio.dev/toolkits/desktime/framework/google-adk) - [LangChain](https://composio.dev/toolkits/desktime/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/desktime/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/desktime/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/desktime/framework/crew-ai) ## Related Toolkits - [Google Sheets](https://composio.dev/toolkits/googlesheets) - Google Sheets is a cloud-based spreadsheet tool for real-time collaboration and data analysis.

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 Mastra AI? Yes, you can. Mastra AI 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. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
