Madison Endurance Sports

April 30, 2026 AImcptech

A FastMCP server for Madison-area endurance athletes — race discovery, NWS race-day weather, and recurring group rides — wrapped in a /race_prep slash command that resolves fuzzy race references ("madtown half" → the right race) and returns a focused pre-race read: how long you’ll be out there, what conditions to expect, and basic nutrition matched to both.

Details

Stack — Python, FastMCP 3.x on Prefect Horizon
Surface — find_races, race_weather, find_group_rides, and the /race_prep prompt
Data — Hand-curated Madison race + group-ride seed (Ironman Wisconsin, Run Madtown, Horribly Hilly, Wisconsin Triathlon Series, Trek Bicycle Madison rides, MadCity Runners…); NWS for inside-7-days forecasts; bundled 30-year NOAA climate normals beyond. Optional RunSignup enrichment when an API key is provided.
Repo — github.com/andywoodruff6/mes-mcp-server

Why it matters

Two design moves I want to be known for. Dual-channel weather — the server refuses to invent race-day forecasts beyond NWS’s honest 7-day horizon, and falls back to a labeled climate normal rather than confidently presenting next week’s weather as race day’s. Fuzzy slash-command UX — slash commands that demand UUIDs are a portfolio piece, not a product; resolving "madtown half" server-side is the difference. The piece collapses six websites of Madison endurance planning into one MCP conversation built on FastMCP idioms a Prefect engineer can read in under five minutes.
