MCP server for interacting with the Scryfall MTG API
Nothing to run from here
Sports Rules is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.

This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.

Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

Work an offside call through the published decision procedure — association football under IFAB Law 11, or ice hockey under NHL Rule 83 — and return every step, not just the verdict. Use this for any "was that offside" question in either sport. The two rules are structurally OPPOSITE and are routinely conflated, and there are four specific things that get answered wrong: SOCCER: 1. HANDS AND ARM
| Parameter | Type | Required | Notes |
|---|---|---|---|
| sport | string | yes | Which rule book. The two are structurally opposite — do not mix them up. |
| attacker | number | no | SOCCER. Position of the attacker along the attacking axis, larger being nearer the opponents’ goal line. Any consistent scale; only the order matters. |
| ball | number | no | SOCCER. Position of the ball, same scale. |
| secondLastDefender | number | no | SOCCER. Position of the SECOND-last opponent, same scale. Usually the last outfield defender, since the goalkeeper is normally the last. |
| foremostPart | string | no | SOCCER. Which part the attacker position describes. Passing an arm or hand is REFUSED with an explanation: only parts that could legally score count, and the boundary is the bottom of the armpit. |
| restart | string | no | SOCCER. There is NO offside offence direct from a throw-in, goal kick, or corner. Always ask which restart it was before answering. |
| inOwnHalf | boolean | no | SOCCER. A player in their own half cannot be in an offside position. |
| involvement | string | no | SOCCER. REQUIRED once the player is in an offside position — the call errors without it rather than assuming. An offside POSITION is not an offence; this is what turns it into one, and "none" is a com |
| lastTouch | string | no | SOCCER. A DELIBERATE play by an opponent resets offside. A deflection, a save, or a rebound off the frame does NOT. |
| deliberatePlayCriteriaMet | array | no | SOCCER. Which of IFAB’s five deliberate-play criteria are met. Reported, not scored — there is no pass mark. |
| rearSkate | number | no | HOCKEY. The trailing skate in centimetres relative to the LEADING EDGE of the blue line — the edge nearer the attacking zone. Negative is the neutral-zone side; positive means it has broken the plane. |
| skateOnIce | boolean | no | HOCKEY. Since 2021 this does NOT affect a zone entry — a skate above the plane is onside. It is decisive when tagging up, where the skate must contact the line. |
| situation | string | no | HOCKEY. zone-entry (default), or tag-up for clearing a delayed offside. The same skate position can give opposite answers. |
| stick | number | no | HOCKEY. Ignored, and reported as ignored. Skates decide it. |
Return the structural differences between soccer offside and hockey offside, dimension by dimension. Use this when someone asks how the two compare, or when you are about to reason about one sport using an intuition from the other — which is the commonest way to get either wrong. They differ on what part of the player is measured, when the picture freezes, whether position alone is an offence, wh

No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.

Any signed-in account that does not publish Sports Rules can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
