Golf Intelligence provides proprietary StrackaGolf course data, updated daily. Learn more at golfintelligence.com.

This repository is the installable Cursor / Grok Bot plugin with handle golf. The Cursor marketplace application source is the public GitHub URL:

https://github.com/golf-data/golf

Marketplace reviewers can submit that URL at cursor.com/marketplace/publish. The catalog title is Golf Intelligence, by Stracka.

The bundled mcp.json connects to the hosted MCP at https://mcp.golfintelligence.com/mcp over Streamable HTTP, so installing the plugin never depends on a local Node build. Your console credentials travel as the X-GI-Client-ID and X-GI-Active-Token headers, filled from the plugin variables declared in .cursor-plugin/plugin.json.

Earlier releases launched node against a plugin-relative dist/index.js. Cursor does not expand the Agent Plugins ${PLUGIN_ROOT} variable, so that placeholder reached Node literally and the connector failed with Cannot find module '.../${PLUGIN_ROOT}/dist/index.js'. The hosted connector removes that failure mode entirely.

mcp.stdio.json keeps the local stdio server for offline and development use. It is not auto-discovered; copy its golf entry into .cursor/mcp.json (using ${workspaceFolder} in a checkout) or point mcpServers at it. Any local stdio config must use ${CURSOR_PLUGIN_ROOT}, never ${PLUGIN_ROOT}. The committed dist/index.js bundle ships in the repository and in the MCPB package, so the stdio path works without running a build first.

The official MCP Registry name is io.github.golf-data/golf. The registry does not accept a bare golf name. Cursor, Agent Plugins, and Claude Code plugin handles remain golf.

Get API access

Sign in at console.golfintelligence.com without a password: enter your email on the login page, request a verification code, then enter the code after it is sent. Create an API Account and configure the plugin's two required variables:

• GI_CLIENT_ID: your Client ID

• GI_ACTIVE_TOKEN: your Active Token

The Active Token is exchanged for a short-lived bearer token. It is not a bearer token; do not paste a bearer token into GI_ACTIVE_TOKEN.

Use credentials from your own console account. This project does not provide demo tokens.

Plans are monthly and can be upgraded or downgraded self-serve in the console:

• Tester: $49/month for 100 credits/month.

• Starter: $399/month for 10,000 credits/month.

For billing, credits, plans, login, or credential help, email support@golfintelligence.com. For course data updates, email data@golfintelligence.com.

Tools and credits

Always search first. search_course_groups is free. Before every paid call, the user must explicitly confirm the stated cost; the server refuses paid tools unless confirm_spend=true.

Authentication

The local stdio server and legacy per-user HTTP credential headers exchange the configured credentials with:

POST https://api.golfintelligence.com/auth/authenticateToken
grant_type=client_credentials
code=<GI_ACTIVE_TOKEN>
client_id=<GI_CLIENT_ID>

It sends the returned access_token as Authorization: Bearer <access_token>, caches it only in memory, and refreshes once after an HTTP 401. Credentials are never logged.

The hosted MCP additionally implements OAuth 2.1 authorization-code flow with S256 PKCE for ChatGPT. Its dedicated authorization page accepts each user's own console Client ID and Active Token, validates them with Golf Intelligence, and binds that account to encrypted access and refresh tokens. See docs/OPENAI-CHATGPT-OAUTH.md for discovery URLs, OpenAI portal settings, reviewer steps, and deployment secrets.

Streamable HTTP

The hosted MCP is available via the official MCP Streamable HTTP transport at:

https://mcp.golfintelligence.com/mcp

The production HTTP entrypoint serves that transport at /mcp and a health check at /health. For OpenAI Apps domain verification it also serves GET /.well-known/openai-apps-challenge as text/plain when OPENAI_APPS_CHALLENGE_TOKEN (or OPENAI_APPS_CHALLENGE) is set; otherwise that path returns 404. Start the HTTP server locally with:

npm run build
PORT=3000 npm run start:http

It binds to 0.0.0.0:$PORT. The existing node dist/index.js stdio entrypoint and all plugin packages remain unchanged.

The HTTP service accepts Golf Intelligence identity in either of these forms:

1. An OAuth bearer token issued by this service after the user signs in with their own GI account.

2. Legacy X-GI-Client-ID and X-GI-Active-Token headers supplied together on every MCP request by existing plugin installs.

There is deliberately no server-wide GI_CLIENT_ID / GI_ACTIVE_TOKEN fallback. The HTTP entrypoint ignores those environment variables, so an anonymous caller cannot inherit a deployment account or spend its credits. Missing or invalid OAuth returns HTTP 401 with an OAuth protected-resource challenge. The Active Token is an exchange credential and must not be sent as an Authorization: Bearer value.

Every tool explicitly advertises these MCP annotations:

• readOnlyHint: true — each tool only retrieves course data.

• openWorldHint: false — no tool writes to public or external systems.

• destructiveHint: false — no tool deletes, overwrites, publishes, or sends anything.

• idempotentHint: true for free search.

• idempotentHint: false for paid tools because every repeated paid invocation can consume credits again.

These sentences can also be used as the annotation justifications in the OpenAI submission form. Paid lookups still require confirm_spend=true at the same credit costs documented above.

Container deployment

Dockerfile builds both transports without embedding credentials. fly.toml configures a small Fly.io service and checks /health. Before the first deploy, confirm that the globally unique Fly app name is available (or change app), then configure the OAuth secrets documented in docs/OPENAI-CHATGPT-OAUTH.md and deploy. At minimum:

fly volumes create oauth_state --region ord --size 1
fly secrets set OAUTH_ENCRYPTION_KEY="$(openssl rand -base64 32)"
fly secrets set OAUTH_ISSUER=https://mcp.golfintelligence.com
fly secrets set OPENAI_APPS_CHALLENGE_TOKEN=...
fly deploy

The mounted volume stores OAuth replay/rotation state, not GI credentials. Run one Machine for this file-backed state store.

Do not configure a shared GI account for hosted HTTP callers. If GI_CLIENT_ID / GI_ACTIVE_TOKEN exist for a separate bootstrap or stdio workflow, they do not authorize HTTP requests.

Set OPENAI_APPS_CHALLENGE_TOKEN to the token shown in OpenAI Platform domain verification. Do not commit that token. After deploy, GET https://mcp.golfintelligence.com/.well-known/openai-apps-challenge should return the token as text/plain.

Tool names and descriptions are baked into the deployed bundle, so the hosted MCP keeps serving the previous copy until it is redeployed. Redeploy before refreshing the marketplace listing, and follow docs/RELEASE.md for the full order across Fly, the marketplace, and the MCP Registry.

For development with Node.js 18 or newer:

npm install
npm test
npm run build
npm run pack:mcpb

pack:mcpb uses the official @anthropic-ai/mcpb pack CLI to produce golf.mcpb and writes its SHA-256 into server.json. GitHub Releases host that asset at https://github.com/golf-data/golf/releases/download/v1.0.2/golf.mcpb.
