mcp-server AGENTS.md

Repository instructions for developing an MCP server that lets AI assistants look up golf courses and send golf data to OpenGolfAPI. MCP is a standard way to give an AI assistant tools it can call.

In plain words
What is it for?
They are for installing, building, testing, and safely contributing to the golf-data MCP server.
Why use it?
They give coding agents the project's purpose, technology, commands, and collaboration rules so they can make changes without guessing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-server AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

AGENTS.md

Instructions for any AI coding agent working in this repository (Codex, Claude, Cursor, Gemini, and others). Project-specific truth lives here so a fresh agent is never guessing.

What this is

A small plug-in that lets AI assistants (Claude, Cursor, etc.) look up golf courses and write golf data back to OpenGolfAPI — "find courses near Chicago", "score this round", "sign this golfer up". It is published to npm as @opengolfapi/mcp-server; users add six lines to their AI client's config and get 56 golf tools. It is a thin client: it contains no golf data and no database. Every tool is a hand-written HTTP call to https://api.opengolfapi.org, which lives elsewhere.

Commands

  • npm install — install dependencies
  • npm run build — build
  • npm run test — test

Working here

  • Always open a pull request; never push straight to the default branch. Other people and agents work in these repos.
  • Verify a claim against the running system before repeating it. A number in a doc without a date and a method is a rumour.
  • Match the surrounding code's style and conventions.
  • On start, read .gstack/inbox.md for messages and proposals from G-Stat (the cross-project advisor). Act on or reply to anything addressed to this repo.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
