## Installation
This MCP server is deployed as a remote HTTP service. No local installation required - just configure your MCP client to connect to the HTTP endpoint.
### For Deployment
If you want to deploy your own instance:
1. Fork this repository
2. Deploy to Vercel (button below)
3. Configure `TODOIST_API_TOKEN` in Vercel environment variables
[](https://vercel.com/new/clone?repository-url=https://github.com/shayonpal/mcp-todoist)
## Configuration
### MCP Clients
Configure your MCP client with the HTTP transport:
#### Claude Desktop / Claude Code
Add to your MCP settings file:
**macOS**: `~/.claude/settings.json`
**Windows**: `%APPDATA%\.claude\settings.json`
**Linux**: `~/.config/claude/settings.json`
```json
{
"mcpServers": {
"todoist": {
"transport": {
"type": "http",
"url": "https://todoist.uberfolks.ca/mcp"
}
}
}
}
```
For local development:
```json
{
"mcpServers": {
"todoist": {
"transport": {
"type": "http",
"url": "http://localhost:3000/mcp"
}
}
}
}
```
## Available Tools
### todoist_tasks
Complete task management with create, get, update, delete, list, complete, uncomplete, and list_completed actions. Supports natural language dates, deadlines, priorities, labels, recurring tasks, and querying completed tasks within time-bounded windows.
**Key parameters**: `action`, `task_id`, `content`, `due_date`, `due_string`, `deadline`, `priority`, `labels`, `project_id`, `completed_query_type`, `since`, `until`
**Completed tasks querying**:
- `list_completed` action retrieves completed tasks
- Query by completion date (3-month window) or due date (6-week window)
- Supports filtering by project, section, workspace, labels, and more
- Cursor-based pagination for large result sets
- Example: Query all tasks completed in September with Work label
```json
{
"action": "list_completed",
"completed_query_type": "by_completion_date",
"since": "2025-09-01T00:00:00Z",
"until": "2025-09-30T23:59:59Z",
"filter_query": "@Work",
"limit": 50
}
```
### todoist_projects
Project management with create, get, update, delete, list, archive, and unarchive actions. Organize work with hierarchical projects and custom views.
**Key parameters**: `action`, `project_id`, `name`, `color`, `is_favorite`, `view_style`
### todoist_sections
Section management within projects for better task organization. Create, get, update, delete, list, and reorder sections.
**Key parameters**: `action`, `section_id`, `project_id`, `name`, `order`
### todoist_comments
Add and manage comments on tasks and projects with file attachment support (up to 15,000 characters).
**Key parameters**: `action`, `comment_id`, `task_id`, `project_id`, `content`, `attachment`
### todoist_filters
Create and manage custom filters for advanced task queries. List, create, update, delete, and query filters.
**Key parameters**: `action`, `filter_id`, `name`, `query`, `color`, `is_favorite`
### todoist_reminders
Set reminders for tasks with three types: relative (X minutes before due), absolute (specific datetime), and location-based (geofenced).
**Key parameters**: `action`, `reminder_id`, `item_id`, `type`, `minute_offset`, `due`, `loc_lat`, `loc_long`
### todoist_labels
Manage personal and shared labels with create, get, update, delete, list, rename, and remove actions. Includes caching for optimal performance.
**Key parameters**: `action`, `label_id`, `name`, `color`, `is_favorite`, `order`
### todoist_bulk_tasks
Perform bulk operations on up to 50 tasks simultaneously. Supports update, complete, uncomplete, and move operations with automatic deduplication and partial execution mode.
**Key parameters**: `action`, `task_ids` (1-50 items), `project_id`, `section_id`, `labels`, `priority`, `due_string`, `deadline_date`
**Supported Actions**:
- `update` - Modify task fields (due date, priority, labels, etc.)
- `complete` - Mark multiple tasks as done
- `uncomplete` - Reopen completed tasks
- `move` - Change project/section/parent for multiple tasks
**Usage Examples**:
```json
// Bulk update due dates for 5 tasks
{
"action": "update",
"task_ids": ["7654321", "7654322", "7654323", "7654324", "7654325"],
"due_string": "tomorrow"
}
// Bulk complete 10 tasks
{
"action": "complete",
"task_ids": ["7654321", "7654322", "7654323", "7654324", "7654325",
"7654326", "7654327", "7654328", "7654329", "7654330"]
}
// Bulk move 7 tasks to different project
{
"action": "move",
"task_ids": ["7654321", "7654322", "7654323", "7654324", "7654325",
"7654326", "7654327"],
"project_id": "2203306141"
}
// Bulk update multiple fields for 8 tasks
{
"action": "update",
"task_ids": ["7654321", "7654322", "7654323", "7654324",
"7654325", "7654326", "7654327", "7654328"],
"priority": 2,
"labels": ["urgent", "work"],
"deadline_date": "2025-12-31"
}
```
**Limitations**:
- Maximum 50 unique tasks per operation (after deduplication)
- Cannot modify `content` (task title), `description`, or `comments` in bulk
- All tasks receive the same field updates
- Performance: <2 seconds for 50-task operations
**Response Structure**:
- Individual results for each task (success/failure)
- Summary counts (total, successful, failed)
- Automatic deduplication metadata
- Execution time tracking
## Rate Limiting
The server implements intelligent rate limiting to respect Todoist API constraints:
- **REST API**: 300 requests/minute (token bucket: 300 capacity, 5 tokens/sec refill)
- **Sync API**: 50 requests/minute (token bucket: 50 capacity, ~0.83 tokens/sec refill)
- **Automatic Retry**: Exponential backoff on 429 responses
- **Batch Operations**: Use for bulk updates to minimize API calls
## Development
