Implementation Reference
- main.py:343-351 (handler)The primary handler function for the MCP tool 'index_perf_7'. It is registered via the @mcp.tool() decorator, fetches 7-day index performance data from pysnowball (ball.index_perf_7), processes timestamps, and returns the result as a dict. Includes input schema via type hints and docstring.
