The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
build_golf_trip Build Golf Trip ~321
AFTER find_nearby_courses, pass its center latitude/longitude, access and holes preferences, and number_of_courses to make a 1-4 course shortlist. You can also start directly with a plain-language location (place, station, address, or US ZIP). Optional tee yardage and slope ranges rank matching tees by fit plus straight-line distance; without tee preferences, courses are nearest-first and missing scorecards are retained. Returns ranked course picks with canonical Stymie URLs, reusable slugs, selection reasons, distance, access, holes, and published tee data when available. Public access excludes unknown/private courses; private picks require the golfer to confirm access. No booking, tee-time availability, transit routing, or drive times are provided. Use returned URLs as citations without inventing slugs.
| Name | Type | Req | Description |
|---|---|---|---|
| access | string | – | – |
| country | string | – | Country code to disambiguate a place; GB means UK |
| distance_miles | – | – | Search radius in miles: one of 5, 10, 20, 25, 50 |

find_nearby_courses Find Nearby Courses ~306
START HERE to plan golf near a place, transit station, address, or US ZIP: pass the place text as location, plus access (public/private/all) and holes (9/18) if known. Coordinates are optional; no slug knowledge is needed. Resolves the location and returns its labeled center and a nearest-first ranked shortlist with canonical Stymie URLs, reusable slugs, straight-line miles, access, holes, and scorecard availability. If the place is ambiguous, ask the golfer to choose a candidate. NEXT call build_golf_trip with the returned latitude/longitude and the same preferences for 1-4 course picks. Use search_courses only for a specific course name. Copy returned URLs verbatim; distances are not drive/transit times.
| Name | Type | Req | Description |
|---|---|---|---|
| access | string | – | – |

Get full details for a specific golf course by a returned Stymie URL or slug.

A recorded open flag is not a live confirmation of seasonal opening or tee-time availability. Covers the US, Canada, UK, Ireland, Australia and New Zealand.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Paste the canonical Stymie course URL or reusable slug returned by search_courses, find_nearby_courses, or build_golf_trip |

No examples provided.
get_deals Get Deals ~129
Get golf-equipment sale offers that were marked in stock when checked within the last 48 hours, with a checked price below list price.

get_leaderboard Get Leaderboard ~129
Rank courses in a state using published tee data: hardest uses highest slope, easiest uses lowest slope among public/municipal courses, and longest uses maximum yardage. Returns each course name, access type, measured value and canonical Stymie URL. Link each recommended course using its returned URL and identify the ranking metric. These are tee-data rankings, not quality ratings or current booking availability; disclose private access.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Ranking category |
| limit | integer | – | Number of results |
| state | string | yes | 2-letter state code, e.g. "NJ" |

You may also pass location here for a proximity search. Returns canonical Stymie URLs, reusable slugs, access, holes, scorecard availability, and straight-line miles when a location is supplied. Copy returned URLs; never construct county slugs. Next: get_course with a returned URL, or build_golf_trip with the resolved center and preferences.

How do I install the Stymie Golf MCP server?
Stymie Golf is a hosted endpoint at https://mcp-production-680d.up.railway.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Stymie Golf MCP server?
Stymie Golf is an MCP server listed in the public MCP registry as io.github.ThatDudeFreak/stymie-golf. Read-only US golf course, scorecard, equipment, deal, and golf-trip data for AI agents. This page covers its hosted endpoint (https://mcp-production-680d.up.railway.app/mcp).
Is the Stymie Golf MCP server safe to use?
Stymie Golf scores 85 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Stymie Golf MCP server expose?
Stymie Golf exposes 12 tools: search_courses, get_course, get_scorecard, get_architect, get_leaderboard, and 7 more. Their descriptions and schemas cost roughly 1,797 tokens of context every time the server is loaded.
Does the Stymie Golf MCP server require authentication?
Its publisher declares no required credentials for Stymie Golf. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the Stymie Golf MCP server still maintained?
Stymie Golf is still listed in the MCP registry, though our most recent checks did not reach this channel. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
