Project Structure

The project follows a modular structure suitable for large applications with clear separation of concerns between models, schemas, routes, and business logic.

Installation

Install UV

# On macOS and Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# On Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

# Or with pip
pip install uv

Setup Project

Clone the repository:

git clone <repository-url>
cd health-api

Install dependencies:

uv sync

Set up environment variables:

cp .env.example .env
# Edit .env with your database credentials and secret key

Database Migrations with Alembic (using UV)

Alembic is used for handling database migrations. All commands below assume you are in the project root directory.

But first off all create up a PostgreSQL database:

CREATE DATABASE health_db;

Generate a New Migration (Autogenerate)

uv run alembic revision --autogenerate -m "Your migration message"

Apply Migrations (Upgrade Database)

uv run alembic upgrade head

Start the application (choose one):

uv run uvicorn app.main:app --host 0.0.0.0 --port 5000 --reload
# Or use the convenience script
chmod +x scripts/start.sh
./scripts/start.sh

Some more required alembic migration commands

These commands are not required during setup but are useful for managing migrations in the future during development.

Downgrade Database (Revert Last Migration)

uv run alembic downgrade -1

View Current Migration Status

uv run alembic current

Show Migration History

uv run alembic history

For more Alembic commands and usage, see the Alembic documentation.

Development

Install development dependencies:

uv sync --group dev

Run tests:

uv run pytest
# Or use the test script
chmod +x scripts/test.sh
./scripts/test.sh

Code formatting:

uv run black app/ tests/
uv run isort app/ tests/

Type checking:

uv run mypy app/

Docker

Build and run with Docker Compose:

docker-compose up --build

This will start both the PostgreSQL database and the FastAPI application.

API Documentation

Once the application is running, visit:

• Swagger UI: http://localhost:5000/docs
• ReDoc: http://localhost:5000/redoc
• MCP ping: check on terminal with the following command

curl -H "Authorization: Bearer <your_bearer_token>" 
-H "Accept: text/event-stream" http://localhost:5000/mcp

Database Migrations

Create a new migration:

uv run alembic revision --autogenerate -m "Description of changes"
# Or use the migration script
chmod +x scripts/migrate.sh
./scripts/migrate.sh "Description of changes"

Apply migrations:

uv run alembic upgrade head

Authentication

• Register a new user: POST /auth/register
• Login to get access token: POST /auth/login
• Use the token in Authorization header: Bearer <token>

Main API Endpoints (after authentication)

After obtaining a JWT access token, you can access the following endpoints:

Package Management with UV

UV provides fast dependency resolution and installation. Useful commands:

• uv sync - Install dependencies from lock file
• uv add <package> - Add a new dependency
• uv remove <package> - Remove a dependency
• uv run <command> - Run command in virtual environment
• uv lock - Update the lock file

MCP Integration

Integration with MCP is done by using the FastApiMCP class from the fastapi_mcp package. The MCP server is mounted to the FastAPI application using the mount method.
