How to integrate Todoist MCP with ChatGPT

ChatGPT is one of the most popular AI tools today, with capabilities ranging from deep research and image generation to writing, coding, and everyday productivity.

Why use Composio over default connectors?

  • Apps with read and write access. Default connectors mostly can read your data. Composio's Todoist integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more.
  • 1,000+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
  • One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
  • Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
  • Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

Prerequisites

  • A ChatGPT account with Plus subscription or higher (Business, Enterprise, Edu, or Pro). We will use ChatGPT Web.
  • Access to the Todoist workspace you want to connect.
  • Composio MCP.

Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.

Step-by-step: Connect Todoist to ChatGPT

1. Enable Developer Mode

In ChatGPT, go to Settings > Apps > Advanced settings and turn on Developer Mode.

2. Add the MCP server

Click Create app, then paste the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
ChatGPT create app flow with Composio MCP URL

3. Authorize in your browser

A browser window will open automatically. Sign in to authorize ChatGPT to access your Composio account.

4. Start using Composio

Composio tools are now available in ChatGPT chats and Deep Research. In every new chat, click the + icon at the bottom, click More, and select Composio to enable tools for that conversation.

What you can do after connecting Todoist

  • Add a high-priority task for today
  • Create a new project called 'Team Offsite'
  • Close all completed tasks from this week
  • Add a comment to your 'Marketing Plan' task

Security + privacy notes (important)

  • Use least-privilege access: Only grant permissions you actually need.
  • Review OAuth permissions before approving: Make sure requested scopes match what you expect Composio and ChatGPT to do.
  • Keep write actions human-reviewed: For actions like sending messages, creating labels, or editing drafts, keep manual confirmation enabled.
  • Be careful with sensitive data: Avoid using this setup with highly sensitive information unless allowed by your personal, company, or client policies.

FAQ

Frequently asked questions

With a standalone Todoist MCP server, the agents and LLMs can only access a fixed set of Todoist tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Todoist and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. ChatGPT 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 Todoist tools.

Yes, absolutely. You can configure which Todoist 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.

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 Todoist data and credentials are handled as safely as possible.

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
