OpenGolfAPI MCP sunucusu

@opengolfapi/mcp-server

Golf, for AI agents — the open data layer for golf. Give your assistant every US golf course (16,845), free, and let it contribute back, sign players in, and run tournaments. Build a whole golf app from a prompt.

OpenGolfAPI is a community-owned commons. One free key, and your agent can read the world's golf data and write to four open standards.

---

The standards (the whole story)

OpenGolfAPI is built on open, composable protocols — implement one or all:

Standard	What it is	You use it to…
OpenShot	A CC0 shape for a launch-monitor shot — one schema every device maps to (Trackman, GSPro, Garmin, …).	Ingest shots from any monitor/sim → log_shot.
Moments	The universal event ingest — any sensor signal (GPS breadcrumb, swing, putt, club, score, pin, condition, presence) as one flexible event.	Send whatever signal you have → submit_moment.
OpenJoin	Signed, scoped, expiring join tokens. One QR/link → everyone who redeems lands in the same round/tournament = the group, linked.	Onboard a foursome or a whole tournament in one tap → create_tournament_invite / join_tournament.
OpenGolf ID	A portable golf identity — "Sign in with OpenGolf." One pseudonymous player_id across every app; handicap + history follow the player everywhere (engines fold by player_id, so a claimed identity's cross-app record just exists).	Give a player one identity the whole ecosystem shares → sign_in_with_opengolf.

The big idea: every shot, moment, and round contributed makes the shared commons better for everyone — a true two-way data layer. Read is free; contributing is how you earn your place in the standard.

What your agent gets

• Read (free, no key): search & compare courses · full scorecards (par / handicap / yardages) · hazards · live weather & climate · nearby places · tee advice.
• Contribute (free key): log_shot, submit_moment → write to the open standards · get_my_shots → read your own data back.
• Identity & tournaments (free key): sign_in_with_opengolf (portable ID) · create_tournament_invite + join_tournament (run an event — handicaps optional, gross or net).

A great golf app is an afternoon, not a year.

Claude Desktop: the config file is claude_desktop_config.json (Settings → Developer → Edit Config). Claude Code: claude mcp add opengolfapi -- npx -y @opengolfapi/mcp-server. Going keyless? Delete the whole env block — every read tool works without it (do NOT paste the placeholder as a key).

First prompt to try: "Find golf courses near Chicago and show me the hardest one."

Which score tool when: casual one-shot scoring → score_round · leagues/tournaments (scores arrive over time, standings matter) → create_competition → record_attempt → finalize_competition · streaming devices/live apps → submit_moment.

Tools

56 tools:

• search_courses — Search US golf courses by name, US state, or location (lat/lng + radius). Returns matching courses with location, type, par. Free, ODbL data.

• propose_correction — Propose a fix to a course FACT field (phone, website, address, architect, year_built, course_name, city, postal_code, course_type). Our AI reviews it (approve/reject/needs_info). Requires a key. Geometry is not correctable here.
• respond_to_review — Respond to a correction that came back as needs_info — add a source or explanation and re-open it for review. Requires a key.
• get_correction — Check the status/verdict of a correction you proposed (approved | rejected | needs_info | applied). Requires a key.
• how_to_build — The safe playbook for building on OpenGolfAPI and contributing data the right way. Call this once before contributing.
• get_passport — FREE (public, no key). Any golfer's shareable record — display name, OpenGolf Member #, courses played, rounds, trophies, referrals. Show a player's golf resume in your app.
• record_referral — Record that one user referred another (a REFERRED_BY edge) — build YOUR app's invite loop on the shared graph, namespaced to your app. Needs a key.
• get_referrals — How many golfers a user has referred (+ the list) — the viral-loop metric for your app. Needs a key.
• about — What OpenGolfAPI is and how to use this MCP server.
• request_sign_in_code — Start "Sign in with OpenGolf" for a person: emails them a 6-digit code. No API key needed. They read you the code, then call complete_sign_in.
• complete_sign_in — Finish sign-in: exchange the 6-digit code for their OpenGolf ID + access token (use as X-OpenGolf-Token to act as them). Pass ref= when another player's invite brought them — it credits the referral.
• create_dev_key — Mint a developer API key bound to an OpenGolf ID (sign in first via request_sign_in_code → complete_sign_in). Returns the key ONCE. First-party rail: no OpenGolf ID, no key.
• sign_in_with_opengolf — Derive a user's OpenGolf ID deterministically from their email (sub = ogid_ + sha256(lower(trim(email)))[:16]) — one line, no redirect. For a VERIFIED session token use request_sign_in_code → complete_sign_in.
• register_webhook — Register an https URL for your domain events (HMAC-signed deliveries, owner-scoped). Requires your key (Authorization: Bearer ogapi_…).
• create_tournament_invite — Create a shareable invite (QR/link); everyone who redeems it joins the SAME event/session. max_uses caps size (foursome=4). Requires key.

• get_conditions — LIVE weather at a course (temp/wind/precip, forecast-model, 15-min cache). FREE. Feeds plays_like.
• link_dev_key — Confirm your OpenGolf ID on an EXISTING key. Sign in first; pass that access_token + the key.
• list_dev_keys — List the keys owned by your OpenGolf ID (prefixes only). Needs access_token from complete_sign_in.
• get_profile — A player's public OpenGolf ID card — name, avatar, links, prefs. Free.
• update_profile — Edit a player's self-asserted profile fields (derived facts can't be set). Requires key (claimed players need their grant).

Money appears only via settled records. Replaces stitching moments+results+live_state. Requires key + session access (participant or compute).
• get_handicap — OpenIndex (beta) — a player's estimated handicap computed from real, notarized rounds (every score stamped when it happened; verifiable by anyone). Not official — provable. Reading your OWN is free with your key; player_id must be the ogid_… form.
• get_showcase — A player's public showcase — the collectibles/records on their OpenGolf ID (og.* namespaces + course.*). Free, keyless: pass their ogid_. Tombstoned (revoked/expired) records hidden. The provable trophy wall.
• verify_record — Verify a record/collectible against the OpenGolf Chain (a signed, hash-linked, Bitcoin-anchored transparency log). Returns the hash + whether it matches + the CLIENT-RECOMPUTE recipe (sha256 of the canonical record) + the anchor. Then you can go further, all keyless: pull a merkle inclusion proof (GET /chain/anchors/:id/inclusion?hash=), verify the checkpoint's RS256 signature against /.well-known/jwks.json, and resolve the Bitcoin (OpenTimestamps) anchor. Free. Trust no one — recompute the hash, check inclusion, resolve Bitcoin yourself.

• verify_chain — Verify a Chain export OR walk the public transparency log (GET /chain/log?subject=), public + keyless — recompute the hash-links, verify each RS256 checkpoint signature against the JWKS, and resolve the Bitcoin anchors; reports tampering and where. The whole history (registry, per-course, master) is independently auditable — trust no one.

The bigger ecosystem — two front doors

Agents come through this MCP; sensors/devices come through OpenGolf Connect (one open connector streaming shots from any launch monitor — R10, MLM2PRO, Uneekor, SkyTrak, Foresight — into POST /v1/shots). Both write to the same open commons. → https://opengolfapi.org/connect
