MCP Todo & Context Server

A lightweight backend service that provides AI clients with two core capabilities:

1. Todo Management: Create, list, complete, and delete todo items per project

2. Project Context: Record and retrieve running context notes about a project's state

Features

• ✅ Per-project todo lists with priority levels

• 📝 Append-only context notes for tracking project state

• 🔄 Resume work summaries (status + recent notes + open todos)

• 🌐 MCP (Model Context Protocol) endpoint for AI clients

• 💾 Persistent JSON file storage

• 🚀 Single-instance deployment with FastAPI + uvicorn

Installation

1. Create Virtual Environment

python -m venv venv

2. Activate Virtual Environment

Windows (PowerShell):

.\venv\Scripts\activate.ps1

Windows (CMD):

venv\Scripts\activate.bat

Linux/Mac:

source venv/bin/activate

3. Install Dependencies

pip install -r requirements.txt

Running the Server

Development Mode (with auto-reload)

python app.py

Or using uvicorn directly:

uvicorn app:app --reload --host 0.0.0.0 --port 8000

Production Mode

uvicorn app:app --host 0.0.0.0 --port 8000

The server will be available at:

• MCP endpoint: http://localhost:8000/mcp

• Health check: http://localhost:8000/health

• API docs: http://localhost:8000/docs

MCP Tools

Data Storage

Data is stored in data/data.json with the following structure:

{
  "projects": {
    "project-name": {
      "name": "project-name",
      "status": "active",
      "context_log": [
        {
          "timestamp": "2026-08-13T10:30:00.000Z",
          "note": "Implemented user authentication"
        }
      ],
      "todos": [
        {
          "id": "20260813103000123456",
          "title": "Add password reset",
          "description": "Implement email-based password reset flow",
          "priority": "high",
          "done": false,
          "created": "2026-08-13T10:30:00.000Z",
          "completed": null
        }
      ]
    }
  }
}

Example Usage

Creating a Todo

# Via MCP tool call
{
  "tool": "create_todo",
  "arguments": {
    "project_name": "my-app",
    "title": "Implement user authentication",
    "description": "Add JWT-based auth with refresh tokens",
