• main.py:100-123 (handler)

  The handler function for the get_daily_graduation_rate tool. It is decorated with @mcp.tool() for registration. Fetches data from Dune query ID 5129526 using the shared get_latest_result helper, processes it into a pivot table showing graduation rates by platform and date using pandas, sorts by date descending, and returns a markdown-formatted table. Catches exceptions and returns error string.

This tool retrieves data from a Dune Analytics query and pivots it to show the graduation rate (e.g., percentage of projects that successfully complete their goals) per day by each platform. Args: limit (int, optional): Maximum number of rows to fetch from the Dune query. Defaults to 1000. Returns: str: A markdown-formatted table of daily graduation rates by platform, or an error message if the query fails.
