Architecture Philosophy

TimeTracker MCP implements a conversational-first architecture that fundamentally reimagines software interaction patterns. Instead of adapting users to interface constraints, the system adapts to natural language expression.

Key Architectural Principles

1. Conversational Primary Interface: All core functionality is accessible through natural language commands via MCP protocol
2. Context Preservation: Conversational state maintains workflow continuity across interactions
3. Extensible Intent System: New capabilities can be added through MCP tools without UI redesign
4. Collaborative Resource Model: Shared clients and projects with individual privacy controls
5. UI as Visualization Layer: Web interface serves as optional dashboard for data visualization and quick operations

MCP Protocol Implementation

TimeTracker MCP implements a comprehensive set of MCP tools that provide complete system functionality through conversational interface:

Core MCP Tools

Client Management Operations:

create_client, list_clients, update_client, deactivate_client

Project Management Operations:

create_project, list_projects, update_project, deactivate_project

Time Tracking Operations:

start_time_tracking, stop_time_tracking, add_manual_time_entry, get_active_time_entry

Reporting and Analytics:

list_time_entries, get_time_summary, calculate_earnings

Interface Hierarchy

1. Primary Interface (MCP Protocol): Complete functionality accessible through natural language commands in any MCP-compatible client
2. Secondary Interface (Web Dashboard): Optional visualization layer for data consultation, basic timer operations, and report generation

This architecture ensures that all business logic remains accessible through conversational interaction while providing traditional UI elements for users who prefer visual interfaces.

Data Model and Collaboration Architecture

TimeTracker MCP implements a hybrid collaboration model that balances team resource sharing with individual privacy:

Resource Sharing Strategy

Shared Resources (Organization-Wide Access):

• Clients: All authenticated users can create, view, modify, and deactivate client records
• Projects: Project management is accessible to all team members across the organization
• Collaborative Ownership: Resources are team-owned rather than user-owned to eliminate duplication

Private Resources (Individual Access):

• Time Entries: Each user's time tracking data remains completely private
• Personal Reports: Users can only access their own productivity metrics and earnings calculations

Data Integrity and Audit Controls

• Referential Integrity: Clients and projects with associated time entries cannot be deactivated
• Audit Trail: All resource creation is tracked via userId field for accountability
• Historical Preservation: System prevents accidental deletion of time tracking context

This architecture eliminates resource duplication while maintaining appropriate privacy boundaries and data integrity.

Quick Start

Prerequisites

• Node.js 18+ and pnpm
• PostgreSQL database (local or cloud)
• Redis instance (optional, recommended for production)

Setup Steps

# Clone repository
git clone https://github.com/lumile/timetracker-mcp.git
cd timetracker-mcp

# Install dependencies
pnpm install

# Copy environment template
cp .env.example .env.local
# 🔑 Fill in the required variables (see Configuration section)
# Generate AUTH_SECRET using: openssl rand -base64 32
# Or visit: https://www.better-auth.com/docs/installation#set-environment-variables

# Generate Better Auth schema (if needed)
npx @better-auth/cli generate --output drizzle/better-auth-schema.ts
# When prompted to overwrite existing schema, answer "yes"

# Generate database migrations
pnpm db:generate
# Creates new Drizzle migration files based on schema changes

# Run database migrations
pnpm db:migrate
# Applies all pending migrations to your database

# Optional: Load sample data for testing
pnpm db:seed
# Creates sample clients, projects, and time entries for development

# For development: Start PostgreSQL container using Docker
./start-postgres.sh
# This will start a PostgreSQL container with the timetracker-mcp database
# The script will display the DATABASE_URL to add to your .env file

# Start development server
pnpm dev

Open http://localhost:3000 and start tracking time through conversation.

Understanding the Collaboration Model

Once running, any authenticated user can:

• View all available clients and projects with list_clients and list_projects
• Create new clients/projects that become available to the entire team
• Modify existing clients/projects created by any team member
• Track time against any project (time entries remain private to each user)
• Generate personal reports and earnings calculations

Clients/projects can only be deactivated if they have no associated time entries, protecting historical data integrity.

MCP vs Dashboard Usage

For full productivity, use MCP tools in your conversational client (like Claude):

• All operations available through natural language
• Context-aware conversations remember your workflow
• No form-filling or clicking required

The web dashboard provides:

• Quick visual overview of your current status
• Charts and visual reports
• Basic timer controls (start/stop)
• Emergency access when MCP client unavailable

Recommended workflow: Use MCP for daily operations, dashboard for occasional visual reviews.

Configuration

Required Environment Variables

| Variable | Description | |----------|-------------| | DATABASE_URL | PostgreSQL connection string (Neon works great) | | BETTER_AUTH_SECRET | Secret issued by Better Auth |

User Registration

By default, TimeTracker MCP allows open registration for new users through the signup page at /app/signup. This means anyone can create an account and start using the application.

emailAndPassword: {
  disableSignUp: true, // Change this to true to disable sign-up for new users
},

By default, email verification is disabled (ENABLE_EMAIL_VERIFICATION=false in .env file and requireEmailVerification: enableEmailVerification is set to false in lib/auth.ts). If you want to enable email verification, you need to:

1. Set ENABLE_EMAIL_VERIFICATION=true in your .env file
2. Configure the Loops.js email service by setting the following variables in your .env file:

`` LOOPS_API_KEY=your_loops_api_key_here LOOPS_EMAIL_VERIFICATION_TEMPLATE_ID=your_template_id_here ``

For more details on authentication configuration options, refer to the Better Auth documentation.

Optional Environment Variables

| Variable | Description | Default | |----------|-------------|---------| | REDIS_URL | Redis instance URL (recommended for production) | Not set | | ENABLE_EMAIL_VERIFICATION | Enable email verification for new users | false | | LOOPS_API_KEY | Loops.js API key (required if email verification is enabled) | Not set | | LOOPS_EMAIL_VERIFICATION_TEMPLATE_ID | Custom email template ID for verification emails | Uses default template |

> Note You can create a free Postgres database on Neon and a free Redis database on Upstash. Redis is optional, but recommended for production use.

Optional Features

Email Verification with Loops.js

TimeTracker MCP includes optional email verification for new user registrations. This feature is disabled by default to keep the setup simple, but you can enable it for enhanced security.

Why Email Verification?

• Enhanced Security: Ensures users have access to their registered email
• Reduced Spam: Prevents registration with fake email addresses
• Better User Experience: Users receive professional verification emails

Setting up Email Verification

1. Create a Loops.js Account

• Sign up at loops.so
• Get your API key from the dashboard

1. Configure Email Template

• Create a new transactional email template in Loops.js
• Use these variables in your template:
• {url} - The verification link
• {homeurl} - Your application's base URL
• Note the template ID for configuration

1. Configure Environment Variables

```bash # Enable email verification ENABLEEMAILVERIFICATION=true

# Add your Loops.js API key LOOPSAPIKEY=yourloopsapikeyhere

# Optional: Use your custom template ID LOOPSEMAILVERIFICATIONTEMPLATEID=yourtemplateid_here ```

1. Restart your application - Email verification is now enabled!

How it Works

• When ENABLE_EMAIL_VERIFICATION=true, new users must verify their email before signing in
• Users receive a verification email via Loops.js with a secure verification link
• Unverified users see a clear message when attempting to sign in
• The feature is completely optional and can be disabled anytime

Using Alternative Email Services

This implementation uses Loops.js, but you can easily integrate other email services:

• Replace the implementation in lib/email.ts
• Keep the same interface for seamless integration
• Examples: SendGrid, Mailgun, AWS SES, etc.
