Provides task management functionality through a Docker container, allowing deployment of the MCP server in containerized environments.
Supports task management in Markdown files with automatic formatting of task lists, including statuses and checkboxes.
Requires Node.js โฅ20 for running the MCP server, with full support for Node.js environments.
Available as an npm package for easy installation and integration into Node.js projects.
Offers full TypeScript support with Zod validation for type-safe task management operations.
Allows managing tasks in YAML format, providing configuration-friendly representation for task data.
Uses Zod for runtime type validation of task data, ensuring data integrity and type safety.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@MCP Tasksadd 'review quarterly report' to my tasks"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

}๐ค AI Integration Tips
To encourage the AI to use these tools, you can start with a prompt like the following, with any path you want with .md (recommended), .json, .yml:
Use mcp-tasks tools to track our work in path/to/tasks.mdIf you are telling it about new or updated tasks, you can append this to the end of your prompt:
use mcp-tasksAdding tasks while AI works: To safely add tasks without interfering with AI operations, use the CLI from a separate terminal:
npx mcp-tasks add "Your new task text" "To Do" 0๐ง Installation Examples
Full configuration with custom environment:
{
"mcpServers": {
"mcp-tasks": {
"command": "npx",
"args": ["-y", "mcp-tasks"],

}
}
}HTTP transport for remote access:
First run the server:
TRANSPORT=http PORT=4680 npx mcp-tasksThen:

}๐ Supported File Formats
Extension | Format | Best For | Auto-Created |
| Markdown | Human-readable task lists | โ |
| JSON | Structured data, APIs | โ |
| YAML | Configuration files | โ |
Format is auto-detected from file extension. All formats support the same features and can be mixed in the same project.
Recommended: Markdown (.md) for human readability and editing
โ ๏ธ Warning: Start with a new file rather than using pre-existing task files to avoid losing non-task content.
๐ ๏ธ Available Tools
When PREFIX_TOOLS=true (default), all tools are prefixed with tasks_:
Tool | Description | Parameters |
| Initialize a task file (creates if missing, supports |
|
| Search tasks with filtering |
|
| Add new tasks to a status |
|
| Update tasks by ID |

Requirements
Node.js โฅ20 - This package requires Node.js version 20 or higher
Common Issues
ERR_MODULE_NOT_FOUND when running npx-tasks
Problem: Error like
Cannot find module '@modelcontextprotocol/sdk/dist/esm/server/index.js'when runningnpx mcp-tasksCause: Corrupt or incomplete npx cache preventing proper dependency resolution
Solution: Clear the npx cache and try again:
npx clear-npx-cache npx mcp-tasksNote: This issue can occur on both Node.js v20 and v22, and the cache clear resolves it
Where are my tasks stored?
Tasks are stored in the file path you specified by the AI in
tasks_setupThe absolute path is returned in every tool call response under
source.pathIf you forgot the location, check any tool response or ask the AI to show it to you
Lost content in Markdown files:
โ ๏ธ The tools will rewrite the entire file, preserving only tasks under recognized status sections
Non-task content (notes, documentation) may be lost when tools modify the file
Use a dedicated task file rather than mixing tasks with other content
Why not just have AI edit the task files directly?
File parsing complexity: AI must read entire files, parse markdown structure, and understand current state - expensive and error-prone
Multi-step operations: Moving a task from "In Progress" to "Done" requires multiple
read_file,grep_search,sedcalls to locate and modify correct sectionsContext loss: Large task files forcing AI to work with incomplete chunks due to token restrictions and lose track of overall structure
State comprehension: AI struggles to understand true project state when reading fragmented file sections - which tasks are actually in progress?
Edit precision: Manual editing risks corrupting markdown formatting, losing tasks, or accidentally modifying the wrong sections
Concurrent editing conflicts: When AI directly edits files, humans can't safely make manual changes without creating conflicts or overwrites
Token inefficiency: Reading+parsing+editing cycles consume far more tokens than structured tool calls with clear inputs/outputs
Safety: AI can accidentally change or delete tasks when directly editing files, but with these tools it cannot rewrite or delete your tasks
