## 👨‍💻 Developer Guidelines

The following sections are intended for developers who want to contribute to or modify the MCP Git Commit Generator.

### Local Development Setup 🛠️

If you prefer not to use Docker for development, you can run the server locally:

**Requirements:**

- [Python](https://www.python.org/) >= 3.13.5
- [uv](https://github.com/astral-sh/uv) (recommended for dependency management and local development)
- [Node.js](https://nodejs.org/en) (for Inspector UI, optional)
- [Python Debugger Extension](https://marketplace.visualstudio.com/items?itemName=ms-python.debugpy) (for debugging, optional)

> **Note**: The MCP CLI dependency is automatically installed via [`uv.lock`](uv.lock:1) when using `uv sync`.

**Installation:**

1. **Clone the repository:**

   ```sh
   git clone https://github.com/theoklitosBam7/mcp-git-commit-generator.git
   cd mcp-git-commit-generator
   ```

2. **Prepare environment:**

    There are two approaches to set up the environment for this project. You can choose either one based on your preference.

    > Note: Reload VSCode or terminal to ensure the virtual environment python is used after creating the virtual environment.

    | Approach | Steps |
    | -------- | ----- |
    | Using `uv` (Recommended) | 1. Create virtual environment and install dependencies: `uv sync --group dev` <br>2. Run VSCode Command "***Python: Select Interpreter***" and select the python from `.venv` directory <br>3. The project is installed in editable mode automatically by `uv sync`. |
    | Using `pip` | 1. Create virtual environment: `python -m venv .venv` <br>2. Run VSCode Command "***Python: Select Interpreter***" and select the python from created virtual environment <br>3. Install dependencies: `pip install -e .`. <br>4. Install pip dev dependencies: `pip install -r requirements-dev.txt`. |

3. **(Optional) Install Inspector dependencies:**

   ```sh
   cd inspector
   npm install
   ```

### 📦 Publishing to PyPI

The project includes an automated PyPI publishing workflow (`.github/workflows/pypi-publish.yml`) that:

- **Triggers on**: Tag pushes matching `v*.*.*` pattern, manual workflow dispatch, or pull requests to main
- **Builds**: Python package distributions using the `build` package
- **Publishes**: Automatically publishes to PyPI using trusted publishing (OIDC) when tags are pushed

To publish a new version:

1. Update the version in `pyproject.toml`
2. Create and push a git tag: `git tag vX.Y.Z && git push origin vX.Y.Z`
3. The workflow will automatically build and publish to PyPI

### 🐳 Building and Running with Docker

You can build and run the MCP Git Commit Generator using Docker. The provided Dockerfile uses a multi-stage build
with [`uv`](https://github.com/astral-sh/uv) for dependency management and runs the server as a non-root user for security.

#### Build the Docker image

```sh
docker build -t mcp-git-commit-generator .
```

#### Run the server in a container (default: stdio transport)

You can run the published image directly from GitHub Container Registry.

```sh
docker run -d \
  --name mcp-git-commit-generator \
  ghcr.io/theoklitosbam7/mcp-git-commit-generator:latest
```

By default, the container runs:

```sh
mcp-git-commit-generator --transport stdio
```

If you want to use SSE transport (for Inspector UI or remote access), override the entrypoint or run manually:

```sh
docker run -d \
  --name mcp-git-commit-generator \
  -p 3001:3001 \
  --entrypoint mcp-git-commit-generator \
  ghcr.io/theoklitosbam7/mcp-git-commit-generator:latest --transport sse --host 0.0.0.0 --port 3001
```

The server will be available at `http://localhost:3001` when using SSE.

### 🖥️ Running the Server Locally

**To run locally (without Docker):**

1. Set up your uv or Python environment as described in the Local Development Setup section.
2. From the project root, run:

  <details>
  <summary>Using uv (Recommended)</summary>

   ```sh
   # Run with uv (uses uv.lock for consistent dependencies)
   uv run mcp-git-commit-generator

   # Or with SSE transport
   uv run mcp-git-commit-generator --transport sse
   ```

  </details>

  <details>
  <summary>Using uv run with module</summary>

   ```sh
   uv run -m mcp_git_commit_generator --transport sse
   ```

  </details>

  <details>
  <summary>mcp-git-commit-generator (installed in environment)</summary>

   ```sh
   # Default stdio transport
   mcp-git-commit-generator

   # With SSE transport
   mcp-git-commit-generator --transport sse
   ```

  </details>

  <details>
  <summary>Using Python directly</summary>

   ```sh
   python -m mcp_git_commit_generator --transport sse
   ```

  </details>

  <br/>

  You can specify other options, for example:

   ```sh
   python -m mcp_git_commit_generator --transport sse --host 0.0.0.0 --port 3001 -v
   ```

   > The server listens on `0.0.0.0:3001` by default when using SSE, or as specified by the options above.

**Note:**

- If you want to use the CLI entrypoint, ensure the package is installed and your environment is activated.
- Do not use positional arguments (e.g., `python -m mcp_git_commit_generator sse`);
always use options like `--transport sse`.
- Available arguments with their values are:
  - `--transport`: Transport type (e.g., `stdio` (default), `sse`).
  - `--host`: Host to bind the server (default: `0.0.0.0`).
  - `--port`: Port to bind the server (default: `3001`).
  - `-v`, `--verbose`: Verbosity level (e.g., `-v`, `-vv`).

### 🔎 Start the Inspector UI

From the `inspector` directory:

```sh
npm run dev:inspector
```

> The Inspector UI will be available at `http://localhost:5173`.

### 🧪 Running Tests

The project includes comprehensive unit tests to ensure reliability:

```sh
# Run all tests (recommended when using uv)
uv run pytest

# Or using pytest directly
pytest

# Run tests with verbose output
uv run pytest -v

# Run tests with coverage
uv run pytest --cov=src/mcp_git_commit_generator

# Run specific test file
uv run pytest tests/test_server.py
```

**Test Coverage:**

- ✅ Tool validation with invalid repository paths
- ✅ Staged and unstaged change detection
- ✅ Git status reporting
- ✅ Commit message generation workflows
- ✅ Error handling for git command failures

### ⚙️ Advanced MCP Server Configuration for Development

The `.vscode/mcp.json` file configures how VS Code and related tools connect to your MCP Git Commit Generator server.
This file defines available server transports and their connection details, making it easy to switch between
different modes (stdio is default, SSE is optional) for development and debugging.

#### Example Development `mcp.json`

```jsonc
{
  "servers": {
    "mcp-git-commit-generator": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "--mount",
        "type=bind,src=${userHome},dst=${userHome}",
        "ghcr.io/theoklitosbam7/mcp-git-commit-generator:latest"
      ]
    },
    "sse-mcp-git-commit-generator": {
      "type": "sse",
      "url": "http://localhost:3001/sse"
    },
    "stdio-mcp-git-commit-generator": {
      "type": "stdio",
      "command": "${command:python.interpreterPath}",
      "args": ["-m", "mcp_git_commit_generator", "--transport", "stdio"]
    },
    "uvx-mcp-git-commit-generator": {
      "command": "uvx",
      "args": ["mcp-git-commit-generator"]
    }
  }
}
```

- **mcp-git-commit-generator**: Runs the server in a Docker container (default: stdio transport), using the published image.
- **sse-mcp-git-commit-generator**: Connects to the MCP server using Server-Sent Events (SSE) at `http://localhost:3001/sse`.
Only useful if you run the server with `--transport sse`.
- **stdio-mcp-git-commit-generator**: Connects using standard input/output (stdio), running the server as a subprocess.
This is the default and recommended for local development and debugging.
- **uvx-mcp-git-commit-generator**: Uses uvx to automatically install and run the package from PyPI.

### 🐞 Debugging the MCP Server

> Notes:
>
> - [MCP Inspector](https://github.com/modelcontextprotocol/inspector) is a visual developer tool for testing
and debugging MCP servers.
> - All debugging modes support breakpoints, so you can add breakpoints to the tool implementation code.
> - **You can test tool arguments directly in the Inspector UI**: When using the Inspector, select a tool and provide
arguments in the input fields to simulate real usage and debug argument handling.

| Debug Mode | Description | Steps to debug |
| ---------- | ----------- | --------------- |
| MCP Inspector | Debug the MCP server using the MCP Inspector. | 1. Install [Node.js](https://nodejs.org/)<br> 2. Set up Inspector: `cd inspector` && `npm install` <br> 3. Open VS Code Debug panel. Select `Debug in Inspector (Edge)` or `Debug in Inspector (Chrome)`. Press F5 to start debugging.<br> 4. When MCP Inspector launches in the browser, click the `Connect` button to connect this MCP server.<br> 5. Then you can `List Tools`, select a tool, input parameters (see arguments above), and `Run Tool` to debug your server code.<br> |

### ⚙️ Default Ports and Customizations

| Debug Mode | Ports | Definitions | Customizations | Note |
| ---------- | ----- | ------------ | -------------- |-------------- |
| MCP Inspector | 3001 (Server, SSE only); 5173 and 3000 (Inspector) | [tasks.json](.vscode/tasks.json) | Edit [launch.json](.vscode/launch.json), [tasks.json](.vscode/tasks.json), [\_\_init\_\_.py](src/__init__.py), [mcp.json](.vscode/mcp.json) to change above ports.| N/A |
