Implementation Reference

src/tools/financial_reports.py:79-87 (handler)

MCP tool handler for get_performance_express_report. Decorated with @app.tool(), validates inputs via run_tool_with_handling, delegates to use case fetch_performance_express_report.

@app.tool()
def get_performance_express_report(code: str, start_date: str, end_date: str, limit: int = 250, format: str = "markdown") -> str:
    """Performance express report within date range."""

        lambda: fetch_performance_express_report(
            active_data_source, code=code, start_date=start_date, end_date=end_date, limit=limit, format=format
        ),
        context=f"get_performance_express_report:{code}:{start_date}-{end_date}",
    )
