Nothing serious here today

Today is the operative word: we check Marathon Scout every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

race

get_race

One race by its Marathon Scout slug (from search_races): every stored date, the next edition's registration state and when it was checked, Boston-qualifier status, and links for registration, official results by year and live tracking (once confirmed). Links are stable marathonscout.com/go URLs that open the current official page; official_url fields name the destination.

races

search_races

Find races for a runner: marathons, half marathons and ultras worldwide by name, city, region, country, distance, date window or Boston-qualifier status ("a flat spring marathon in Ohio", "halves near Denver in October"). Returns up to 10 races (20 with an API key) with the next race date, registration status and Marathon Scout guide URL. With no text query, results are in date order.

Marathon Scout — questions

Answers built from our own checks of this server.

What can Marathon Scout do?

It exposes 2 tools, read directly from the server on our last check. Among them: get_race, search_races. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Marathon Scout working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 85 of 85 checks got a reply (100.0%), average response time 360 ms. The bar chart above shows every period we have measured.

How do I connect Marathon Scout?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Marathon Scout need an API key?

No. Marathon Scout completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Marathon Scout?

It answers our handshake in 360 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
