Travmaskinen MCP — Nordic harness racing data for AI agents

The first MCP server for Nordic harness racing (trav). Gives Claude, ChatGPT and any MCP-compatible agent direct access to Swedish, Norwegian, Danish and Finnish trotting data: upcoming pool games, full startlists, how the betting public is splitting the pool, and a model-derived win probability for every runner.

Built on a dataset of 204 000 races and 2.06 million starts since 2012.

What your agent can do with it

• "What's running in the V85 this Saturday?"
• "In tonight's V64, which horses does the model rate higher than the betting public does?"
• "Build me a table of every runner in leg 3 with driver, trainer and win probability."
• "Which horse in this round is the biggest overlay?"

Getting a key

The data is a paid product. Request a key at https://travmaskinen.se/api-access.

The server loads without a key and every tool will tell you how to get one, so you can install first and decide after.

Tools

list_upcoming_races

Upcoming Nordic pool games — V85, V86, V64, V65, GS75 — with track, first start time and leg count. Returns the game_id needed by the other tool.

Argument	Type	Default	Notes
days	integer 1–14	7	How many days ahead to look

Gallop races are excluded: the model is trained on trotting only, and returning probabilities for a sport it never learned would be quietly wrong rather than obviously missing.

get_race_analysis

One full round: every leg, every runner.

Field	Meaning
horse, driver, trainer	Who is running
pool_pct	Share of the betting pool on this horse — what the crowd thinks
pool_blend_prob	Win probability, 0–1. Sums to 1 per leg across live runners
implied_odds	1 / pool_blend_prob
value	Model probability ÷ market probability. > 1 = underbet
scratched	Non-runner. Probability fields are null — it isn't racing

Every response also carries a field_reference explaining each field inline, so an agent never has to guess what a number means.

Rate limits

1 000 calls/month and 60 calls/minute on the standard key. The tools return a clear message rather than a raw HTTP error when either is hit.

Configuration

Variable	Required	Purpose
TRAVMASKINEN_API_KEY	yes	Your API key
TRAVMASKINEN_API_URL	no	Override the base URL (testing)

Notes

Data covers Nordic harness racing (trot), not thoroughbred flat racing. If you need UK or US thoroughbred data, this is the wrong server — and if you need Nordic trot, as far as we know this is the only one.

Times are Europe/Stockholm. Probabilities are model output, not betting advice.
