General steps: 1. Navigate to the project directory 2. Install dependencies using the appropriate package manager 3. Set up environment variables (see .env.example files) 4. Run the application using the provided scripts 5. Test the API endpoints using the provided examples ### Quick Start Examples ```bash # Python project cd test/sample-projects/python/user_management pip install -r requirements.txt python cli.py # Java project cd test/sample-projects/java/user-management mvn spring-boot:run # Go project cd test/sample-projects/go/user-management go run cmd/server/main.go # JavaScript project cd test/sample-projects/javascript/user-management npm install npm run dev # TypeScript project cd test/sample-projects/typescript/user-management npm install npm run dev ``` ## MCP Server Testing To test the Code Index MCP server with these projects: 1. **Set Project Path**: Use the `set_project_path` tool to point to a project directory 2. **Index Files**: The server will automatically index all files in the project 3. **Search Testing**: Test various search queries and patterns 4. **Analysis Testing**: Use the analysis tools to examine code structure 5. **Performance Testing**: Measure response times and resource usage ### Example MCP Commands ```bash # Set project path set_project_path /path/to/test/sample-projects/python/user_management # Search for user-related functions search_code_advanced "def create_user" --file-pattern "*.py" # Find all authentication-related code search_code_advanced "auth" --fuzzy true # Get file summary get_file_summary models/user.py # Find TypeScript interfaces search_code_advanced "interface.*User" --regex true --file-pattern "*.ts" ``` ## Contributing When adding new test projects: 1.
