feat: implement comprehensive thinking modes and migrate to google-genai

Major improvements to thinking capabilities and API integration:

- Remove all output token limits for future-proof responses
- Add 5-level thinking mode system: minimal, low, medium, high, max
- Migrate from google-generativeai to google-genai library
- Implement native thinkingBudget support for Gemini 2.5 Pro
- Set medium thinking as default for all tools, max for think_deeper

🧠 Thinking Modes:
- minimal (128 tokens) - simple tasks
- low (2048 tokens) - basic reasoning
- medium (8192 tokens) - default for most tools
- high (16384 tokens) - complex analysis
- max (32768 tokens) - default for think_deeper

🔧 Technical Changes:
- Complete migration to google-genai>=1.19.0
- Remove google-generativeai dependency
- Add ThinkingConfig with thinking_budget parameter
- Update all tools to support thinking_mode parameter
- Comprehensive test suite with 37 passing unit tests
- CI-friendly testing (no API key required for unit tests)
- Live integration tests for API verification

🧪 Testing & CI:
- Add GitHub Actions workflow with multi-Python support
- Unit tests use mocks, no API key required
- Live integration tests optional with API key
- Contributing guide with development setup
- All tests pass without external dependencies

# Contributing to Gemini MCP Server
Thank you for your interest in contributing! This guide explains how to set up the development environment and contribute to the project.
## Development Setup
1. **Clone the repository**
```bash
git clone https://github.com/BeehiveInnovations/gemini-mcp-server.git
cd gemini-mcp-server
```
2. **Create virtual environment**
```bash
python -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
```
3. **Install dependencies**
```bash
pip install -r requirements.txt
```
## Testing Strategy
### Two Types of Tests
#### 1. Unit Tests (Mandatory - No API Key Required)
- **Location**: `tests/test_*.py` (except `test_live_integration.py`)
- **Purpose**: Test logic, mocking, and functionality without API calls
- **Run with**: `python -m pytest tests/ --ignore=tests/test_live_integration.py -v`
- **GitHub Actions**: ✅ Always runs
- **Coverage**: Measures code coverage
#### 2. Live Integration Tests (Optional - API Key Required)
- **Location**: `tests/test_live_integration.py`
- **Purpose**: Verify actual API integration works
- **Run with**: `python tests/test_live_integration.py` (requires `GEMINI_API_KEY`)
- **GitHub Actions**: 🔒 Only runs if `GEMINI_API_KEY` secret is set
### Running Tests
```bash
# Run all unit tests (CI-friendly, no API key needed)
python -m pytest tests/ --ignore=tests/test_live_integration.py -v
# Run with coverage
python -m pytest tests/ --ignore=tests/test_live_integration.py --cov=. --cov-report=html
# Run live integration tests (requires API key)
export GEMINI_API_KEY=your-api-key-here
python tests/test_live_integration.py
```
## Code Quality
### Formatting and Linting
```bash
# Install development tools
pip install black ruff
# Format code
black .
# Lint code
ruff check .
```
### Pre-commit Checks
Before submitting a PR, ensure:
- [ ] All unit tests pass: `python -m pytest tests/ --ignore=tests/test_live_integration.py -v`
- [ ] Code is formatted: `black --check .`
- [ ] Code passes linting: `ruff check .`
- [ ] Live tests work (if you have API access): `python tests/test_live_integration.py`
## Adding New Features
### Adding a New Tool
1. **Create tool file**: `tools/your_tool.py`
2. **Inherit from BaseTool**: Implement all required methods
3. **Add system prompt**: Include prompt in `prompts/tool_prompts.py`
4. **Register tool**: Add to `TOOLS` dict in `server.py`
5. **Write tests**: Add unit tests that use mocks
6. **Test live**: Verify with live API calls
### Testing New Tools
```python
# Unit test example (tools/test_your_tool.py)
@pytest.mark.asyncio
@patch("tools.base.BaseTool.create_model")
async def test_your_tool(self, mock_create_model):
mock_model = Mock()
mock_model.generate_content.return_value = Mock(
candidates=[Mock(content=Mock(parts=[Mock(text="Expected response")]))]
)
mock_create_model.return_value = mock_model
tool = YourTool()
result = await tool.execute({"param": "value"})
assert len(result) == 1
assert "Expected response" in result[0].text
```
## CI/CD Pipeline
The GitHub Actions workflow:
1. **Unit Tests**: Run on all Python versions (3.10, 3.11, 3.12)
2. **Linting**: Check code formatting and style
3. **Live Tests**: Only run if `GEMINI_API_KEY` secret is available
### Key Features:
- **✅ No API key required for PRs** - All contributors can run tests
- **🔒 Live verification available** - Maintainers can verify API integration
- **📊 Coverage reporting** - Track test coverage
- **🐍 Multi-Python support** - Ensure compatibility
## Contribution Guidelines
### Pull Request Process
1. **Fork the repository**
2. **Create a feature branch**: `git checkout -b feature/your-feature`
3. **Make your changes**
4. **Add/update tests**
5. **Run tests locally**: Ensure unit tests pass
6. **Submit PR**: Include description of changes
### Code Standards
- **Follow existing patterns**: Look at existing tools for examples
- **Add comprehensive tests**: Both unit tests (required) and live tests (recommended)
- **Update documentation**: Update README if adding new features
- **Use type hints**: All new code should include proper type annotations
- **Keep it simple**: Follow SOLID principles and keep functions focused
### Security Considerations
- **Never commit API keys**: Use environment variables
- **Validate inputs**: Always validate user inputs in tools
- **Handle errors gracefully**: Provide meaningful error messages
- **Follow security best practices**: Sanitize file paths, validate file access
## Getting Help
- **Issues**: Open an issue for bugs or feature requests
- **Discussions**: Use GitHub Discussions for questions
- **Documentation**: Check the README for usage examples

## Advanced Features
### Enhanced Thinking Models
All tools support a `thinking_mode` parameter that controls Gemini's thinking budget for deeper reasoning:
```
"Use gemini to review auth.py with thinking_mode=max"
"Get gemini to analyze the architecture with thinking_mode=medium"
```
**Thinking Modes:**
- `minimal`: Minimum thinking (128 tokens for Gemini 2.5 Pro)
- `low`: Light reasoning (2,048 token thinking budget)
- `medium`: Balanced reasoning (8,192 token thinking budget - default for all tools)
- `high`: Deep reasoning (16,384 token thinking budget)
- `max`: Maximum reasoning (32,768 token thinking budget - default for think_deeper)
**When to use:**
- `minimal`: For simple, straightforward tasks
- `low`: For tasks requiring basic reasoning
- `medium`: For most development tasks (default)
- `high`: For complex problems requiring thorough analysis
- `max`: For the most complex problems requiring exhaustive reasoning
**Note:** Gemini 2.5 Pro requires a minimum of 128 thinking tokens, so thinking cannot be fully disabled
## Configuration
The server includes several configurable properties that control its behavior:
### Model Configuration
- **`DEFAULT_MODEL`**: `"gemini-2.5-pro-preview-06-05"` - The default Gemini model used
- **`DEFAULT_MODEL`**: `"gemini-2.5-pro-preview-06-05"` - The latest Gemini 2.5 Pro model with native thinking support
- **`MAX_CONTEXT_TOKENS`**: `1,000,000` - Maximum input context (1M tokens for Gemini 2.5 Pro)
- **`MAX_OUTPUT_TOKENS`**: `32,768` - Maximum output tokens per response
### Temperature Defaults
Different tools use optimized temperature settings:
@@ -389,14 +420,6 @@ Different tools use optimized temperature settings:
- **`TEMPERATURE_BALANCED`**: `0.5` - Used for general chat (balanced creativity/accuracy)
- **`TEMPERATURE_CREATIVE`**: `0.7` - Used for deep thinking and architecture (more creative)
### Customizing Output Length
Each tool accepts an optional `max_tokens` parameter to override the default:
```
"Use gemini to analyze main.py with max_tokens 16000"
"Get gemini to think deeper about this design with max_tokens 50000"
```
Note: The maximum supported output is 32,768 tokens for Gemini 2.5 Pro.
## Installation
@@ -456,6 +479,40 @@ We welcome contributions! The modular architecture makes it easy to add new tool
See existing tools for examples.
## Testing
### Unit Tests (No API Key Required)
The project includes comprehensive unit tests that use mocks and don't require a Gemini API key:
```bash
# Run all unit tests
python -m pytest tests/ --ignore=tests/test_live_integration.py -v
# Run with coverage
python -m pytest tests/ --ignore=tests/test_live_integration.py --cov=. --cov-report=html
```
### Live Integration Tests (API Key Required)
To test actual API integration:
```bash
# Set your API key
export GEMINI_API_KEY=your-api-key-here
# Run live integration tests
python tests/test_live_integration.py
```
### GitHub Actions CI/CD
The project includes GitHub Actions workflows that:
- **✅ Run unit tests automatically** - No API key needed, uses mocks
- **✅ Test on Python 3.10, 3.11, 3.12** - Ensures compatibility
- **✅ Run linting and formatting checks** - Maintains code quality
- **🔒 Run live tests only if API key is available** - Optional live verification
The CI pipeline works without any secrets and will pass all tests using mocked responses. Live integration tests only run if a `GEMINI_API_KEY` secret is configured in the repository.
