Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Library for connecting AI agents to Todoist. Includes tools that can be integrated into LLMs, enabling them to access and modify a Todoist account on the user's behalf.

These tools can be used both through an MCP server, or imported directly in other projects to integrate them to your own AI conversational interfaces.

Using tools

1. Add this repository as a dependency

npm install @doist/todoist-mcp

2. Import the tools and plug them to an AI

Here's an example using Vercel's AI SDK.

import { findTasksByDate, addTasks } from '@doist/todoist-mcp'
import { TodoistApi } from '@doist/todoist-sdk'
import { streamText } from 'ai'

// Create Todoist API client
const client = new TodoistApi(process.env.TODOIST_API_KEY)

// Helper to wrap tools with the client
function wrapTool(tool, todoistClient) {
return {
...tool,
execute(args) {
return tool.execute(args, todoistClient)
},
}
}

const result = streamText({
model: yourModel,
system: 'You are a helpful Todoist assistant',
tools: {
findTasksByDate: wrapTool(findTasksByDate, client),
addTasks: wrapTool(addTasks, client),
},
})

Using as an MCP server

Quick Start

You can run the MCP server directly with npx:

npx @doist/todoist-mcp

Setup Guide

The Todoist MCP server is available as a streamable HTTP service for easy integration with various AI clients:

Primary URL (Streamable HTTP): https://ai.todoist.net/mcp

Connect

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions

What is the Todoist MCP server?

A set of tools to connect to AI agents, to allow them to use Todoist on a user's behalf. Includes MCP support.

What tools does Todoist expose?

7 in total: 7 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Todoist safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Todoist need?

It reads MCP_TOKEN_BUDGET and TODOIST_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Todoist run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as @doist/todoist-mcp at 13.3.1.

How current is this page?

The grade is for one exact copy of the source (00a9d4828791), read on 2026-09-29. The repository is watched and re-audited when it changes.
