By the end, you'll have a working Google Tasks agent that can add a new task to your work list, list all tasks due this week, delete completed tasks from your shopping list through natural language commands. This guide will help you understand how to give your Mastra AI agent real control over a Google Tasks account through Composio's Google Tasks MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Google Tasks with - [ChatGPT](https://composio.dev/toolkits/googletasks/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/googletasks/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/googletasks/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/googletasks/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/googletasks/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/googletasks/framework/codex) - [Cursor](https://composio.dev/toolkits/googletasks/framework/cursor) - [VS Code](https://composio.dev/toolkits/googletasks/framework/vscode) - [OpenCode](https://composio.dev/toolkits/googletasks/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/googletasks/framework/openclaw) - [Hermes](https://composio.dev/toolkits/googletasks/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/googletasks/framework/cli) - [Google ADK](https://composio.dev/toolkits/googletasks/framework/google-adk) - [LangChain](https://composio.dev/toolkits/googletasks/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/googletasks/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/googletasks/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/googletasks/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 Google Tasks tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Google Tasks 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 Google Tasks 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 Google Tasks MCP server, and what's possible with it? The Google Tasks MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google Tasks account. It provides structured and secure access to your to-do lists and tasks, so your agent can create task lists, add or update tasks, reorganize and clean up your lists, and fetch or manage your action items automatically. - Intelligent task list management: Ask your agent to create new to-do lists, fetch existing ones, or remove lists you no longer need—all without manual clicks. - Automated task creation and updates: Let your agent add new tasks, set due dates, or update existing to-dos to keep your lists current and organized. - Efficient task organization and movement: Move tasks between lists, reorder them, or set parent/child relationships so your priorities always stay clear. - Fast cleanup and deletion: Direct your agent to clear completed tasks or delete specific items and lists, helping you declutter swiftly and securely. - Detailed task retrieval and review: Have your agent pull details on any task or list so you can review upcoming deadlines, notes, and status at a glance. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `GOOGLETASKS_CLEAR_TASKS` | Clear tasks | Permanently clears all completed tasks from a specified google tasks list; this action is destructive and idempotent. | | `GOOGLETASKS_CREATE_TASK_LIST` | Create a task list | Creates a new task list with the specified title. | | `GOOGLETASKS_DELETE_TASK` | Delete task | Deletes a specified task from a given task list in google tasks. | | `GOOGLETASKS_DELETE_TASK_LIST` | Delete task list | Permanently deletes an existing google task list, identified by `tasklist id`, along with all its tasks; this operation is irreversible. | | `GOOGLETASKS_GET_TASK` | Get Task | Use to retrieve a specific google task if its `task id` and parent `tasklist id` are known. | | `GOOGLETASKS_GET_TASK_LIST` | Get task list | Retrieves a specific task list from the user's google tasks if the `tasklist id` exists for the authenticated user. | | `GOOGLETASKS_INSERT_TASK` | Insert Task | Creates a new task in a given `tasklist id`, optionally as a subtask of an existing `task parent` or positioned after an existing `task previous` sibling, where both `task parent` and `task previous` must belong to the same `tasklist id` if specified. | | `GOOGLETASKS_LIST_TASK_LISTS` | List task lists | Fetches the authenticated user's task lists from google tasks; results may be paginated. | | `GOOGLETASKS_LIST_TASKS` | List Tasks | Retrieves tasks from a google tasks list; all date/time strings must be rfc3339 utc, and `showcompleted` must be true if `completedmin` or `completedmax` are specified. | | `GOOGLETASKS_MOVE_TASK` | Move Task | Moves the specified task to another position in the destination task list. | | `GOOGLETASKS_PATCH_TASK` | Patch Task | Partially updates an existing task (identified by `task id`) within a specific google task list (identified by `tasklist id`), modifying only the provided attributes from `taskinput` (e.g., `title`, `notes`, `due` date, `status`) and requiring both the task and list to exist. | | `GOOGLETASKS_PATCH_TASK_LIST` | Patch task list | Updates the title of an existing google tasks task list. | | `GOOGLETASKS_UPDATE_TASK` | Update Task | Updates the specified task. | | `GOOGLETASKS_UPDATE_TASK_LIST` | Update Task List | Updates the authenticated user's specified task list. | ## Supported Triggers | Trigger slug | Name | Description | |---|---|---| | `GOOGLETASKS_NEW_TASK_CREATED_TRIGGER` | New Task Created | Triggers when a new task is created in a Google Tasks list. Uses timestamp filtering (updatedMin) to efficiently detect new tasks. | | `GOOGLETASKS_NEW_TASK_LIST_CREATED_TRIGGER` | New Task List Created | Triggers when a new Google Tasks task list is created. This trigger monitors Google Tasks and fires when new task lists are detected. | | `GOOGLETASKS_TASK_DETAILS_CHANGED_TRIGGER` | Task Details Changed | Triggers when a specific task's details change. This trigger monitors a single Google Task and fires when any of its details (title, notes, status, due date, completion, position) are modified. | | `GOOGLETASKS_TASK_LIST_CHANGED_TRIGGER` | Task List Changed | Triggers when a task list changes (title or content updates). This trigger monitors a specific Google Tasks list and fires when changes are detected. | | `GOOGLETASKS_TASK_UPDATED_TRIGGER` | Task Updated | Triggers when an existing task is updated in a Google Tasks list. This trigger monitors a specific task list and fires when tasks are modified. | ## Creating MCP Server - Stand-alone vs Composio SDK The Google Tasks MCP server is an implementation of the Model Context Protocol that connects your AI agent to Google Tasks. It provides structured and secure access so your agent can perform Google Tasks 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 Google Tasks 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 Google Tasks What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "googletasks" for Google Tasks 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: ["googletasks"], }, ); const composioMCPUrl = session.mcp.url; console.log("Google Tasks 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 Google Tasks 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: "googletasks-mastra-agent", instructions: "You are an AI agent with Google Tasks 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 Google Tasks 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: { googletasks: 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: ["googletasks"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { googletasks: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "googletasks-mastra-agent", instructions: "You are an AI agent with Google Tasks 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: { googletasks: 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 Google Tasks 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 Google Tasks MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/googletasks/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/googletasks/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/googletasks/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/googletasks/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/googletasks/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/googletasks/framework/codex) - [Cursor](https://composio.dev/toolkits/googletasks/framework/cursor) - [VS Code](https://composio.dev/toolkits/googletasks/framework/vscode) - [OpenCode](https://composio.dev/toolkits/googletasks/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/googletasks/framework/openclaw) - [Hermes](https://composio.dev/toolkits/googletasks/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/googletasks/framework/cli) - [Google ADK](https://composio.dev/toolkits/googletasks/framework/google-adk) - [LangChain](https://composio.dev/toolkits/googletasks/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/googletasks/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/googletasks/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/googletasks/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 Google Tasks MCP server, the agents and LLMs can only access a fixed set of Google Tasks tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Google Tasks 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 Google Tasks tools. ### Can I manage the permissions and scopes for Google Tasks while using Tool Router? Yes, absolutely. You can configure which Google Tasks 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 Google Tasks data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
