Focuslog

FocusLog: Desktop Activity MCP Server

A background server that logs your desktop activity, calculates your Actions Per Minute (APM), and provides a clean, anonymized timeline of your work on demand. It's designed to be a data source for personal analytics or AI assistants.

This server uses FastMCP for communication, Ollama for AI-powered anonymization, and standard Linux tools for activity tracking.

Features

• Activity Logging: Periodically records the title of the currently focused window.
• APM Tracking: Calculates your Actions Per Minute (APM) based on keyboard and mouse activity.
• Timeline Aggregation: Groups consecutive activities into a compressed, easy-to-read timeline.
• Two-Stage Anonymization:
  1. Hard-coded Filter: Guarantees removal of user-defined sensitive keywords.
  2. LLM Anonymization: Uses a local Ollama model to intelligently remove any other PII.
• Title Sanitization: Cleans up and shortens excessively long window titles.
• Reliable & Configurable: Features log rotation, graceful shutdown, and all settings are managed in a separate config.py file.
• Systemd Service: Can be run as a persistent background service for maximum reliability.

Requirements

System Dependencies

Important

Compatibility Note: This server is designed specifically for Linux desktop environments running on the X11 display server. It relies on tools that are part of the X11 ecosystem and will not work on Windows, macOS, or native Wayland sessions.

You must have the following command-line tools and libraries installed:

• xdotool: For getting the active window title.
• xprintidle: For checking user idle time.
• ollama: For running the local LLM.
• PyGObject: For D-Bus communication (used to detect screen lock).

On Debian/Ubuntu/Linux Mint, you can install them all with:

sudo apt update
sudo apt install xdotool xprintidle python3-gi python3-gi-cairo gir1.2-gtk-3.0

For Ollama, follow the official installation instructions at ollama.com. After installing, make sure you have pulled a model:

ollama pull gemma3

Python Dependencies

The project requires Python 3.8+ and uses a virtual environment to manage its packages.

Installation & Setup

1. Clone the repository:

   git clone https://github.com/your-username/focuslog.git
   cd focuslog
   

2. Create a virtual environment: We need to create a virtual environment that has access to the system's PyGObject library.

   python3 -m venv venv --system-site-packages
   

3. Activate the environment and install packages:

   source venv/bin/activate
   pip install -r requirements.txt
   deactivate
   

   (You can leave the environment by typing deactivate).

4. Create your configuration file:

   cp config.py.example config.py
   

5. Edit your configuration: Open config.py in a text editor.

   • Crucially, fill in the FORBIDDEN_KEYWORDS list with any personal data you want to ensure is always removed.
   • Adjust other settings like OLLAMA_MODEL or MCP_PORT if you wish.

Usage

Manual Start (for testing)

To run the server manually for testing, first activate the virtual environment:

source venv/bin/activate
python focuslog.py

The server will start and show logs in the console. Press Ctrl+C to stop it.

Running as a Service (Recommended)

For continuous, reliable background operation, it's best to run FocusLog as a systemd user service. This will automatically start the server when you log in and restart it if it ever crashes.

1. Prepare the service file:

   cp focuslog.service.example focuslog.service
   

2. Edit focuslog.service: Open the file and replace the placeholder paths with your actual ones.

   • WorkingDirectory=/home/your_username/path/to/focuslog -> e.g., WorkingDirectory=/home/dw/projects/focuslog
   • ExecStart=... -> Update the path to venv/bin/python and focuslog.py as well.
   • Important: Do NOT add User= or Group= lines. systemd --user handles this automatically.

3. Install and enable the service:

   mkdir -p ~/.config/systemd/user
   cp focuslog.service ~/.config/systemd/user/
   systemctl --user daemon-reload
   systemctl --user enable --now focuslog.service
   

   The --now flag both enables it for future logins and starts it immediately.

4. Manage the service:

   • Check status: systemctl --user status focuslog.service
   • View logs: journalctl --user -u focuslog.service -f (-f to follow live)
   • Stop: systemctl --user stop focuslog.service
   • Start: systemctl --user start focuslog.service

How It Works

The server runs two main background threads:

1. APM Sensor: Checks for user input every half-second to update an activity "tick" counter.
2. Logger: Every 10 seconds, it:
   • Gets the current active window title.
   • Sanitizes the title (shortens it and applies custom rules).
   • Calculates the current APM based on ticks in the last minute.
   • Saves the sanitized title and APM to an SQLite database.

When the get_activity_log tool is called via an MCP client, it:

1. Fetches the raw data from the database.
2. Performs two-stage anonymization on all unique window titles, caching the results for performance.
3. Aggregates the data into a clean timeline.
4. Returns the timeline as a string.
