"""my-mcp MCP server with dynamic tool loading.
This server automatically discovers and loads tools from the src/tools/ directory.
Each tool file should contain a function decorated with @mcp.tool().
Usage Examples:
# Stdio mode (default MCP transport)
python src/main.py
# HTTP mode with MCP protocol over HTTP
python src/main.py --transport http
# Custom host/port
python src/main.py --transport http --host localhost --port 8080
# Stateless HTTP mode
python src/main.py --transport http --stateless-http
# Environment variable mode
MCP_TRANSPORT_MODE=http python src/main.py
