Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Microsoft To Do with - [OpenAI Agents SDK](https://composio.dev/toolkits/microsoft_todo/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/microsoft_todo/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/microsoft_todo/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/microsoft_todo/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/microsoft_todo/framework/codex) - [OpenClaw](https://composio.dev/toolkits/microsoft_todo/framework/openclaw) - [Hermes](https://composio.dev/toolkits/microsoft_todo/framework/hermes-agent) - [LangChain](https://composio.dev/toolkits/microsoft_todo/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/microsoft_todo/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/microsoft_todo/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/microsoft_todo/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/microsoft_todo/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/microsoft_todo/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/microsoft_todo/framework/autogen) ## TL;DR Here's what you'll learn: - Get a Microsoft To Do account set up and connected to Composio - Install the Google ADK and Composio packages - Create a Composio Tool Router session for Microsoft To Do - Build an agent that connects to Microsoft To Do through MCP - Interact with Microsoft To Do using natural language ## What is Google ADK? Google ADK (Agents Development Kit) is Google's framework for building AI agents powered by Gemini models. It provides tools for creating agents that can use external services through the Model Context Protocol. Key features include: - Gemini Integration: Native support for Google's Gemini models - MCP Toolset: Built-in support for Model Context Protocol tools - Streamable HTTP: Connect to external services through streamable HTTP - CLI and Web UI: Run agents via command line or web interface ## What is the Microsoft To Do MCP server, and what's possible with it? The Microsoft To Do MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Microsoft To Do account. It provides structured and secure access so your agent can perform Microsoft To Do operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `MICROSOFT_TODO_COMPLETE_TASK` | Complete Task | Mark a Microsoft To Do task as completed. Convenience wrapper that always PATCHes status='completed'; the server auto-sets completedDateTime. Use Update Task to reopen a task (status='notStarted') or to change other fields. | | `MICROSOFT_TODO_CREATE_CHECKLIST_ITEM` | Create Checklist Item | Add a checklist item (subtask) to a Microsoft To Do task. Only display_name is required; the created item is returned with a GUID id, displayName, isChecked, and createdDateTime. | | `MICROSOFT_TODO_CREATE_TASK` | Create Task | Create a task in a Microsoft To Do task list. Only title is required. Dates are passed as flat ISO-8601 strings plus a shared timezone; the tool builds the Graph dateTimeTimeZone objects. Notes are passed as body_content (+ body_content_type). NOTE: To Do treats due dates as whole days — the time component of due_date_time is normalized to midnight on save. | | `MICROSOFT_TODO_CREATE_TASK_LIST` | Create Task List | Create a new Microsoft To Do task list. | | `MICROSOFT_TODO_DELETE_CHECKLIST_ITEM` | Delete Checklist Item | Delete a checklist item (subtask) from a Microsoft To Do task. This permanently removes the checklist item (this cannot be undone). | | `MICROSOFT_TODO_DELETE_TASK` | Delete Task | Delete a task from a Microsoft To Do task list. WARNING: this also permanently removes the task's checklist items and linked resources. | | `MICROSOFT_TODO_DELETE_TASK_ATTACHMENT` | Delete Task Attachment | Permanently delete a file attachment from a Microsoft To Do task. This cannot be undone. | | `MICROSOFT_TODO_DELETE_TASK_LIST` | Delete Task List | Delete a Microsoft To Do task list. WARNING: this cascades — all tasks in the list and their checklist items are permanently deleted. | | `MICROSOFT_TODO_DOWNLOAD_TASK_ATTACHMENT` | Download Task Attachment | Download one file attached to a Microsoft To Do task. The file is offloaded to storage and returned as a downloadable reference rather than inline base64. | | `MICROSOFT_TODO_GET_CHECKLIST_ITEM` | Get Checklist Item | Get a single Microsoft To Do checklist item (subtask) by its id, within a task in a task list. | | `MICROSOFT_TODO_GET_CURRENT_USER` | Get Current User | Return the profile of the Microsoft account connected to this toolkit (whoami / connection verification). Useful to confirm which mailbox the To Do tasks belong to before other operations. | | `MICROSOFT_TODO_GET_TASK` | Get Task | Get a single Microsoft To Do task by its id, within a task list. Set include_checklist_items=true to expand its checklist items inline. | | `MICROSOFT_TODO_GET_TASK_ATTACHMENT` | Get Task Attachment | Get metadata for one file attached to a Microsoft To Do task. Use Download Task Attachment to retrieve the file contents. | | `MICROSOFT_TODO_GET_TASK_LIST` | Get Task List | Get a single Microsoft To Do task list by its id. | | `MICROSOFT_TODO_LIST_CHECKLIST_ITEMS` | List Checklist Items | List the checklist items (subtasks) of a To Do task. Auto-paginates so all subtasks are returned at once as {items: [...]}. | | `MICROSOFT_TODO_LIST_TASK_ATTACHMENTS` | List Task Attachments | List the files attached to a Microsoft To Do task. Returns attachment metadata without file contents, one page at a time, plus a next_cursor. | | `MICROSOFT_TODO_LIST_TASK_LISTS` | List Task Lists | List the To Do task lists owned by the connected user. The built-in default list has wellknown_list_name='defaultList'; user-created lists have wellknown_list_name='none'. Always returns at least the default list. Select the default list by id or wellknown_list_name, never by the localized display_name. | | `MICROSOFT_TODO_LIST_TASKS` | List Tasks | List the tasks in a To Do task list. Checklist items (subtasks) are NOT returned by default; set include_checklist_items=true to expand them inline. Returns one page of tasks plus a next_cursor for the next page. | | `MICROSOFT_TODO_UPDATE_CHECKLIST_ITEM` | Update Checklist Item | Update a checklist item (subtask) of a Microsoft To Do task: rename it (display_name) and/or check/uncheck it (is_checked). Partial update: only the fields you pass are changed; at least one is required. Setting is_checked=true marks the subtask done. | | `MICROSOFT_TODO_UPDATE_TASK` | Update Task | Update fields of an existing Microsoft To Do task (title, notes, importance, status, due/start/reminder dates, categories). Partial update: only the fields you pass are changed; unset fields are left untouched. To mark a task done set status='completed' (or use the dedicated Complete Task tool). | | `MICROSOFT_TODO_UPDATE_TASK_LIST` | Update Task List | Rename a Microsoft To Do task list (updates its displayName). | | `MICROSOFT_TODO_UPLOAD_TASK_ATTACHMENT` | Upload Task Attachment | Attach a file up to 25 MB to a Microsoft To Do task. The tool automatically uses a single request for files under 3 MB and a chunked upload session for larger files. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Microsoft To Do MCP server is an implementation of the Model Context Protocol that connects your AI agent to Microsoft To Do. It provides structured and secure access so your agent can perform Microsoft To Do 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: - A Google API key for Gemini models - A Composio account and API key - Python 3.9 or later installed - Basic familiarity with Python ### 1. Getting API Keys for Google and Composio Google API Key - Go to [Google AI Studio](https://aistudio.google.com/app/apikey) and create an API key. - Copy the key and keep it safe. You will put this in GOOGLE_API_KEY. Composio API Key and User ID - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Go to Settings → API Keys and copy your Composio API key. Use this for COMPOSIO_API_KEY. - Decide on a stable user identifier to scope sessions, often your email or a user ID. Use this for COMPOSIO_USER_ID. ### 2. Install dependencies Inside your virtual environment, install the required packages. What's happening: - google-adk is Google's Agents Development Kit - composio connects your agent to Microsoft To Do via MCP - python-dotenv loads environment variables ```bash pip install google-adk composio python-dotenv ``` ### 3. Set up ADK project Set up a new Google ADK project. What's happening: - This creates an agent folder with a root agent file and .env file ```bash adk create my_agent ``` ### 4. Set environment variables Save all your credentials in the .env file. What's happening: - GOOGLE_API_KEY authenticates with Google's Gemini models - COMPOSIO_API_KEY authenticates with Composio - COMPOSIO_USER_ID identifies the user for session management ```bash GOOGLE_API_KEY=your-google-api-key COMPOSIO_API_KEY=your-composio-api-key COMPOSIO_USER_ID=your-user-id-or-email ``` ### 5. Import modules and validate environment What's happening: - os reads environment variables - Composio is the main Composio SDK client - GoogleProvider declares that you are using Google ADK as the agent runtime - Agent is the Google ADK LLM agent class - McpToolset lets the ADK agent call MCP tools over HTTP ```python import os import warnings from composio import Composio from dotenv import load_dotenv from google.adk.agents.llm_agent import Agent from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams from google.adk.tools.mcp_tool.mcp_toolset import McpToolset load_dotenv() warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*") GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") ``` ### 6. Create Composio client and Tool Router session What's happening: - Authenticates to Composio with your API key - Declares Google ADK as the provider - Spins up a short-lived MCP endpoint for your user and selected toolkit - Stores the MCP HTTP URL for the ADK MCP integration ```python composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=COMPOSIO_USER_ID, toolkits=["microsoft_todo"], ) COMPOSIO_MCP_URL = composio_session.mcp.url, print(f"Composio MCP URL: {COMPOSIO_MCP_URL}") ``` ### 7. Set up the McpToolset and create the Agent What's happening: - Connects the ADK agent to the Composio MCP endpoint through McpToolset - Uses Gemini as the model powering the agent - Lists exact tool names in instruction to reduce misnamed tool calls ```python composio_toolset = McpToolset( connection_params=StreamableHTTPConnectionParams( url=COMPOSIO_MCP_URL, headers={"x-api-key": COMPOSIO_API_KEY} ) ) root_agent = Agent( model="gemini-2.5-flash", name="composio_agent", description="An agent that uses Composio tools to perform actions.", instruction=( "You are a helpful assistant connected to Composio. " "You have the following tools available: " "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, " "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. " "Use these tools to help users with Microsoft To Do operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ### 8. Run the agent Execute the agent from the project root. The web command opens a web portal where you can chat with the agent. What's happening: - adk run runs the agent in CLI mode - adk web . opens a web UI for interactive testing ```bash # Run in CLI mode adk run my_agent # Or run in web UI mode adk web ``` ## Complete Code ```python import os import warnings from composio import Composio from composio_google import GoogleProvider from dotenv import load_dotenv from google.adk.agents.llm_agent import Agent from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams from google.adk.tools.mcp_tool.mcp_toolset import McpToolset load_dotenv() warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*") GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") composio_client = Composio(api_key=COMPOSIO_API_KEY, provider=GoogleProvider()) composio_session = composio_client.create( user_id=COMPOSIO_USER_ID, toolkits=["microsoft_todo"], ) COMPOSIO_MCP_URL = composio_session.mcp.url composio_toolset = McpToolset( connection_params=StreamableHTTPConnectionParams( url=COMPOSIO_MCP_URL, headers={"x-api-key": COMPOSIO_API_KEY} ) ) root_agent = Agent( model="gemini-2.5-flash", name="composio_agent", description="An agent that uses Composio tools to perform actions.", instruction=( "You are a helpful assistant connected to Composio. " "You have the following tools available: " "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, " "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. " "Use these tools to help users with Microsoft To Do operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ## Conclusion You've successfully integrated Microsoft To Do with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Microsoft To Do using natural language commands. Key takeaways: - The Tool Router approach dynamically routes requests to the appropriate Microsoft To Do tools - Environment variables keep your credentials secure and separate from code - Clear agent instructions reduce tool calling errors - The ADK web UI provides an interactive interface for testing and development You can extend this setup by adding more toolkits to the toolkits array in your session configuration. ## How to build Microsoft To Do MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/microsoft_todo/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/microsoft_todo/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/microsoft_todo/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/microsoft_todo/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/microsoft_todo/framework/codex) - [OpenClaw](https://composio.dev/toolkits/microsoft_todo/framework/openclaw) - [Hermes](https://composio.dev/toolkits/microsoft_todo/framework/hermes-agent) - [LangChain](https://composio.dev/toolkits/microsoft_todo/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/microsoft_todo/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/microsoft_todo/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/microsoft_todo/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/microsoft_todo/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/microsoft_todo/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/microsoft_todo/framework/autogen) ## 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 Microsoft To Do MCP server, the agents and LLMs can only access a fixed set of Microsoft To Do tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Microsoft To Do and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Google ADK? Yes, you can. Google ADK 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 Microsoft To Do tools. ### Can I manage the permissions and scopes for Microsoft To Do while using Tool Router? Yes, absolutely. You can configure which Microsoft To Do 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 Microsoft To Do data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
