## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Ticktick.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Ticktick account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to Ticktick
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect Ticktick to Atomic Agent

### Connect Ticktick to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in Ticktick. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Ticktick account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## What is the Ticktick MCP server, and what's possible with it?

The Ticktick MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Ticktick account. It provides structured and secure access to your task lists and projects, so your agent can create, manage, and organize tasks, complete or delete items, and streamline your productivity workflows automatically.
- Automated task creation and editing: Let your agent add new tasks, set deadlines, and update task details across your Ticktick projects with ease.
- Project management and organization: Direct your agent to create, retrieve, or delete entire projects, keeping your workspace tidy and aligned with your priorities.
- Seamless task completion and cleanup: Ask your agent to mark tasks as complete or delete tasks you've finished or no longer need, helping you stay on top of your to-do list.
- Comprehensive project data retrieval: Have your agent fetch detailed project information, including all associated tasks and columns, for quick overviews or reporting.
- Effortless OAuth2 authentication management: Benefit from a streamlined, agent-guided authorization flow that securely connects your Ticktick account with minimal friction.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `TICKTICK_COMPLETE_TASK` | Complete Task | Marks a TickTick task as complete. Requires both the project_id and task_id, which can be obtained from TICKTICK_LIST_ALL_TASKS or TICKTICK_CREATE_TASK actions. This action is idempotent - completing an already-completed task will succeed without error. Completed tasks are removed from default/active views and appear only in completed task filters. |
| `TICKTICK_CREATE_PROJECT` | Create Project | Create a new project (list) in TickTick. Projects organize tasks and notes. Use this to set up a new project with optional customizations like color, view mode, and type. The created project's ID can be used with other actions like TICKTICK_CREATE_TASK. |
| `TICKTICK_CREATE_TASK` | Create Task | Tool to create a new task in TickTick. Use after you have task details such as title, dates, and optional reminders or subtasks. |
| `TICKTICK_DELETE_PROJECT` | Delete TickTick Project | Permanently deletes a TickTick project by its ID. All tasks within the project will also be deleted. Note: This operation is idempotent - deleting a non-existent project ID returns success. Use TICKTICK_GET_USER_PROJECT to list available projects and their IDs before deletion. |
| `TICKTICK_DELETE_TASK` | Delete Task | Tool to permanently delete a specific task — irreversible, no recovery. Use when you need to remove a task from a project after confirming both project and task IDs. Returns an empty data object on success; check status/success flags rather than response payload. When moving tasks between projects via create+delete, comments and history are lost. |
| `TICKTICK_GET_PROJECT_BY_ID` | Get Project By ID | Tool to retrieve a specific TickTick project by its unique ID. Use when you need detailed information about a particular project after obtaining its project ID. |
| `TICKTICK_GET_PROJECT_WITH_DATA` | Get project with data | Retrieve a project's associated data (incomplete tasks, columns). IMPORTANT: This endpoint only returns INCOMPLETE tasks. Completed tasks are automatically filtered out by the TickTick API. An empty tasks list means either the project has no tasks at all, or all tasks have been completed. For completed tasks, check the TickTick app or web interface directly. Columns are only present for kanban-style projects; list-view projects return an empty columns array. Join tasks to columns via each task's columnId field. For large projects, results may paginate at ~100 items per page — iterate all pages and deduplicate by taskId. Multiple tasks can share the same title; always use taskId for follow-up create, update, or delete calls. All filtering by name, tag, or other fields must be done client-side. Scope is project-only — Inbox and other projects are excluded. |
| `TICKTICK_GET_TASK_BY_PROJECT_AND_ID` | Get Task By Project And ID | Tool to retrieve a specific TickTick task by project ID and task ID. Use when you need detailed information about a particular task within a project. |
| `TICKTICK_GET_USER_PROJECT` | Get User Projects | Retrieves all projects accessible to the authenticated user, including personal and shared projects. Use this tool to list available projects before creating tasks or to get project IDs for other operations. Returns project metadata including name, color, view mode, and organization details. Always use returned projectId values (not project names) when calling TICKTICK_CREATE_TASK, TICKTICK_UPDATE_TASK, or TICKTICK_GET_PROJECT_WITH_DATA. The inbox project may not appear in results — omit projectId in TICKTICK_CREATE_TASK to target the inbox. Non-kanban projects return an empty columns array; check viewMode before assuming columns exist. |
| `TICKTICK_LIST_ALL_TASKS` | List All Tasks | Tool to list all open/undone tasks across all user projects in one call. This is a composite operation that internally fetches all projects and aggregates their tasks. Use when you need a comprehensive view of pending work across the entire account. Note: Only returns open/undone tasks; completed task history is not available in TickTick OpenAPI v1. |
| `TICKTICK_OAUTH2_AUTHORIZATION_STEP1` | Generate OAuth2 Authorization URL | Tool to generate the TickTick OAuth2 authorization URL. Use to redirect the user to obtain the authorization code (step 1). Re-run this tool if downstream TickTick calls return HTTP 401 (expired/invalid token) to obtain a fresh authorization code. |
| `TICKTICK_UPDATE_PROJECT` | Update Project | Tool to update an existing project. Use when you need to modify project details like name, color, sort order, view mode, or kind after selecting a project ID. |
| `TICKTICK_UPDATE_TASK` | Update Task | Tool to update an existing task. Use after confirming the taskId and projectId. Omitting optional fields resets them to null — include all existing field values in every payload. Cannot move a task to a different project; use TICKTICK_CREATE_TASK + TICKTICK_DELETE_TASK instead. Fields outside the input schema (e.g., columnId, assignee) are silently ignored. |

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Complete Code

None listed.

## Conclusion

### Use Ticktick from Atomic Agent
With your account connected, ask Atomic Agent to work with Ticktick in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Ticktick MCP?

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

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent 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 Ticktick tools.

### Can I manage the permissions and scopes for Ticktick while using Tool Router?

Yes, absolutely. You can configure which Ticktick 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 Ticktick data and credentials are handled as safely as possible.
