# MCP Scheduler

A robust task scheduler server built with Model Context Protocol (MCP) for scheduling and managing various types of automated tasks.

![License](https://img.shields.io/badge/license-MIT-blue.svg)

## Overview

MCP Scheduler is a versatile task automation system that allows you to schedule and run different types of tasks:

- **Shell Commands**: Execute system commands on a schedule
- **API Calls**: Make HTTP requests to external services
- **AI Tasks**: Generate content through OpenAI models
- **Reminders**: Display desktop notifications with sound

The scheduler uses cron expressions for flexible timing and provides a complete history of task executions. It's built on the Model Context Protocol (MCP), making it easy to integrate with AI assistants and other MCP-compatible clients.

## Features

- **Multiple Task Types**: Support for shell commands, API calls, AI content generation, and desktop notifications
- **Cron Scheduling**: Familiar cron syntax for precise scheduling control
- **Run Once or Recurring**: Option to run tasks just once or repeatedly on schedule
- **Execution History**: Track successful and failed task executions
- **Cross-Platform**: Works on Windows, macOS, and Linux
- **Interactive Notifications**: Desktop alerts with sound for reminder tasks
- **MCP Integration**: Seamless connection with AI assistants and tools
- **Robust Error Handling**: Comprehensive logging and error recovery

## Installation

### Prerequisites

- Python 3.10 or higher
- [uv](https://astral.sh/uv) (recommended package manager)

### Installing uv (recommended)

```bash
# For Mac/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# For Windows (PowerShell)
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
```

After installing uv, restart your terminal to ensure the command is available.

### Project Setup

```bash
# Clone the repository
git clone https://github.com/phialsbasement/mcp-scheduler.git
cd mcp-scheduler

# Create and activate a virtual environment with uv
uv venv
source .venv/bin/activate  # On Unix/MacOS
# or
.venv\Scripts\activate     # On Windows

# Install dependencies with uv
uv pip install -r requirements.txt
```

### Standard pip installation (alternative)

If you prefer using standard pip:

```bash
# Clone the repository
git clone https://github.com/phialsbasement/mcp-scheduler.git
cd mcp-scheduler

# Create and activate a virtual environment
python -m venv .venv
source .venv/bin/activate  # On Unix/MacOS
# or
.venv\Scripts\activate     # On Windows

# Install dependencies
pip install -r requirements.txt
```

## Usage

### Running the Server

```bash
# Run with default settings (stdio transport)
python main.py

# Run with server transport on specific port
python main.py --transport sse --port 8080

# Run with debug mode for detailed logging
python main.py --debug
```

### Integrating with Claude Desktop or other MCP Clients

To use your MCP Scheduler with Claude Desktop:

1. Make sure you have Claude Desktop installed
2. Open your Claude Desktop App configuration at:
   - macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
   - Windows: `%APPDATA%\Claude\claude_desktop_config.json`
3. Create the file if it doesn't exist, and add your server:

```json
{
  "mcpServers": [
    {
      "type": "stdio",
      "name": "MCP Scheduler",
      "command": "python",
      "args": ["/path/to/your/mcp-scheduler/main.py"]
    }
  ]
}
```

Alternatively, use the `fastmcp` utility if you're using the FastMCP library:

```bash
# Install your server in Claude Desktop
fastmcp install main.py --name "Task Scheduler"
```

await scheduler.add_command_task(
    name="Backup Database",
    schedule="0 0 * * *",  # Midnight every day
    command="pg_dump -U postgres mydb > /backups/mydb_$(date +%Y%m%d).sql",
    description="Daily database backup",
    do_only_once=False  # Recurring task
)
```

### Adding an API Task

```python
await scheduler.add_api_task(
    name="Fetch Weather Data",
    schedule="0 */6 * * *",  # Every 6 hours
    api_url="https://api.weather.gov/stations/KJFK/observations/latest",
    api_method="GET",
    description="Get latest weather observations",
    do_only_once=False
)
```

### Adding an AI Task

```python
await scheduler.add_ai_task(
    name="Generate Weekly Report",
    schedule="0 9 * * 1",  # 9 AM every Monday
    prompt="Generate a summary of the previous week's sales data.",
    description="Weekly sales report generation",
    do_only_once=False
)
```

### Adding a Reminder Task

```python

    message="Don't forget the team standup meeting!",
    title="Meeting Reminder",
    do_only_once=False
)
```

## MCP Auto-discovery Endpoint

When running in SSE (HTTP) mode, MCP Scheduler exposes a well-known endpoint for tool/schema auto-discovery:

- **Endpoint:** `/.well-known/mcp-schema.json` (on the HTTP port + 1, e.g., if your server runs on 8080, the schema is on 8081)
- **Purpose:** Allows clients and AI assistants to discover all available MCP tools and their parameters automatically.

### Example

If you run:

```bash
python main.py --transport sse --port 8080
```

You can access the schema at:

```
http://localhost:8081/.well-known/mcp-schema.json
```

### Example Response

```json
{
  "tools": [
    {
      "name": "list_tasks",
      "description": "List all scheduled tasks.",
      "endpoint": "list_tasks",
      "method": "POST",
      "parameters": {
        "type": "object",
        "properties": {},
        "required": [],
        "additionalProperties": false
      }
    },
    {
      "name": "add_command_task",
      "description": "Add a new shell command task.",
      "endpoint": "add_command_task",
      "method": "POST",
      "parameters": {
        "type": "object",
        "properties": {
          "name": {"type": "string"},
          "schedule": {"type": "string"},
          "command": {"type": "string"},
          "description": {"type": "string"},
          "enabled": {"type": "boolean"},
          "do_only_once": {"type": "boolean"}
        },
        "required": ["name", "schedule", "command"],
        "additionalProperties": false
      }
    }
    // ... more tools ...
  ]
}
```

This schema is generated automatically from the registered MCP tools and always reflects the current server capabilities.
