Implementation Reference

• main.py:125-148 (handler)

  The primary handler function for the 'get_daily_active_addresses' tool. Decorated with @mcp.tool() for automatic registration in FastMCP. Fetches data from Dune query 5002622, pivots daily active wallets by platform using pandas, sorts descending by date, and returns markdown table or error.
  @mcp.tool() def get_daily_active_addresses(limit: int = 1000) -> str: """ Fetch the daily count of active wallet addresses interacting with Solana memecoin launchpads. This tool retrieves data from a Dune Analytics query and pivots it to show the number of unique active wallets 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 active wallets by platform, or an error message if the query fails. """ try: data = get_latest_result(5002622, limit=limit) df = pd.DataFrame(data) df['date_time'] = pd.to_datetime(df['date_time']).dt.date pivot_df = df.pivot(index="date_time", columns="platform", values="daily_active_wallets") pivot_df = pivot_df.sort_index(ascending=False) return pivot_df.to_markdown() except Exception as e: return str(e)
