Give your AI assistant football data for 93 leagues — including the lower
divisions other sources skip: tables, results, fixtures, goal timing, a public
baseline model and Monte Carlo season projections from
football-charts.com.
FC publishes probabilities and a settled track record — not betting tips.
Every model signal is published before kickoff and graded after; the
get_track_record tool returns that ledger.
No key needed
Every tool works without an API key at 300 requests/day per IP (20/min).
A free key lifts that to 5,000/day, 60/min — get one in seconds:
curl -X POST https://footballcharts-backend.onrender.com/api/v1/keys/register/ \
-H 'Content-Type: application/json' \
-d '{"email":"you@example.com"}'
The key (fc_...) is shown once — store it. Both tiers: all 93 leagues
(top and lower divisions, women's leagues), current + previous season,
model probabilities and daily 10,000-run Monte Carlo projections, no
betting odds (the historical odds archive is a paid dataset at
football-charts.com/data).
Use it on claude.ai (web or mobile) — nothing to install
Settings → Connectors → Add custom connector, then paste:
https://mcp.football-charts.com/mcp
That is the keyless tier. With a key, paste
https://mcp.football-charts.com/fc_your_key_here/mcp instead (a connector
field accepts only a URL, so the key travels in it; keys are read-only, free
and replaceable). Clients that can send headers use
POST https://mcp.football-charts.com/mcp with Authorization: Bearer fc_….
Use with Claude Desktop — one-click extension
Download footballcharts-mcp-<version>.mcpb from the
latest release
and open it; Claude Desktop installs it. The API key field can stay empty.
Use with Claude Desktop — manual config
claude_desktop_config.json (FC_API_KEY is optional since 0.4.0):
{
"mcpServers": {
"football-charts": {
"command": "npx",
"args": ["-y", "footballcharts-mcp"],
"env": { "FC_API_KEY": "fc_your_key_here" }
}
}
}
Use with Claude Code
claude mcp add football-charts -e FC_API_KEY=fc_your_key_here -- npx -y footballcharts-mcp
Ten read-only tools. Descriptions are written for the model: when to use it,
what comes back, one example. about_football_charts needs no key.
| tool | use it for |
|---|
about_football_charts | What this source covers and does not, how keys and seasons work, how to phrase probabilities. Call first when unsure. |
list_leagues | Turn a league name into its key; see the seasons your key can read. |
get_league_table | Standings, form, expected points; view=luck or goals for alternative rankings. |
get_results | Finished matches with FT/HT scores and first-goal minute; filter by team, cap with last. |
get_fixtures | Upcoming matches with the baseline model's calibrated probabilities across markets. |
get_match | One upcoming match in full, by slug. |
get_season_projection | Title / top-4 / relegation probabilities and points ranges, 10,000 simulations, daily. |
get_team | One team: table row, match log, goal timing, stats. |
get_goal_timing | Goals per 15-minute bin per team with peak_bins; pass team for one team. |
get_track_record | The public settled ledger of every published model lean, losses included. |
The model is a public baseline (Dixon-Coles). It is calibrated and it does
not beat the bookmaker market; get_track_record is the proof. Per-bookmaker
opening and closing odds for 91 leagues, 2020 onward, are a paid dataset at
football-charts.com/data.
Changelog
- 0.5.0 — every tool has an
outputSchema and returns structuredContent; descriptions rewritten from the consumer side (purpose → when to use a sibling instead → one example); get_match drops storage internals. The tool list is ~6k tokens (was ~3k) — the schemas are the cost. Two deliberate choices: list_leagues keeps its list_ prefix because it enumerates everything rather than fetching one thing, and league stays a free string rather than an enum of the 93 keys (an enum would add ~700 tokens to every tool; list_leagues resolves a name in one call). Schema leaves are untyped so that an unexpected null never fails a call; the field types are what the API returns (numbers for counts and probabilities, ISO dates, 'home:away' score strings).
- 0.4.1 — registry entry declares the hosted endpoint (
remotes) so connector directories list it; get_results ordering wording clarified (chronological, last=N keeps the latest N).
- 0.4.0 — a key is optional: the API serves keyless callers at 300/day
per IP (20/min) and its 429 says how to get a free key;
about and
list_leagues guidance updated; MCPB desktop-extension bundle
(manifest.json, icon); registry isRequired: false for FC_API_KEY.
- 0.3.0 — descriptions rewritten for the model (when / returns / example);
new
about_football_charts orientation tool (keyless); get_rankings
folded into get_league_table via view; get_goal_timing gains a
team filter and peak_bins guidance; one structured log line per tool
call on stderr (tool, ok, ms, key prefix — never arguments).
- 0.2.0 — hosted Streamable HTTP transport, read-only annotations, key
accepted from header, path or query for registry gateways.
Things to ask
- "How does the Allsvenskan title race look after this weekend?"
- "When does Flamengo usually score — early or late?"
- "Show me the K League table, and who's overperforming what the market expected."
- "Which team in Serie B hasn't conceded in the first 15 minutes?"
- "What is Football Charts' actual prediction track record this season?"
