Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http balldontlie https://mcp.balldontlie.io/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

    "balldontlie": {
      "url": "https://mcp.balldontlie.io/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Balldontlie MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 14 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

BALLDONTLIE MCP Server

Remote Model Context Protocol server for the BALLDONTLIE sports API. The tool catalog is generated from the vendored public OpenAPI specifications so endpoint methods, paths, parameters, and constraints stay aligned with the API source.

The current generated surface contains 529 tools from 27 specifications: Account, ATP, Bundesliga, college baseball, Counter-Strike, Dota 2, EPL, F1, FIFA World Cup, La Liga, Ligue 1, League of Legends, MLB, MLS, MMA, NBA, NCAAB, NCAAF, NCAAW, NFL, NHL, PGA, Serie A, UCL, Valorant, WNBA, and WTA. /health reports the authoritative runtime count and deployed revision.

Authentication

Every MCP request requires a BALLDONTLIE API key:

Authorization: Bearer YOUR_API_KEY

Initialization, tool listing, authenticated documentation, and API operations that are public outside the MCP validate the supplied key before proceeding. Other tool calls forward only the Authorization header to the corresponding authenticated BALLDONTLIE endpoint.

Public service metadata is limited to /health and /.well-known/mcp-config. /api/docs requires a valid API key.

Sensitive Account tools

The complete Account API surface is registered, but the following tools are disabled by default:

account_signup
account_rotate_api_key
account_change_subscription
account_cancel_subscription
account_create_checkout
account_get_billing_portal

They can create credentials, change billing state, or return sensitive hosted billing-session URLs. A deployment must set ENABLE_SENSITIVE_ACCOUNT_TOOLS=true exactly to enable them. Enabling the flag means those values may intentionally enter the authenticated caller's MCP transcript. Other spellings, casing, or whitespace fail closed.

account_get_me remains available but always omits the api_key response field.

MCP request example

curl https://mcp.balldontlie.io/mcp \

-H 'Content-Type: application/json' \ -H 'Authorization: Bearer YOUR_API_KEY' \ -d '{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "nba_get_teams", "arguments": {} } }'

Use tools/list to retrieve the current catalog, input schemas, and MCP read-only/destructive annotations.

Development

npm ci

npm run check:openapi npm test npm run build

The tests independently compare every generated operation and input against all vendored specifications. They also cover legacy tool-name compatibility, exact array query serialization, path/body dispatch, credential-safe errors and logs, API-key validation limits, and Account safety controls. Tests never call a live Account mutation.

Updating from the API source

Copy balldontlie-2/marketing/public/openapi.yml to openapi.yml.
Copy every balldontlie-2/marketing/public/openapi/*.yml file into openapi/.
Update scripts/openapi-source.json to the source API commit.
Run npm run generate:openapi.
Run npm test and npm run build.

Generated src/tools/*.ts, src/schemas/*.ts, and registry files are checked in and must not be edited manually. Runtime does not parse YAML and has no production YAML-parser dependency.

Configuration

Variable	Default	Purpose
`PORT`	`3000`	HTTP port
`BACKEND_API_URL`	`https://api.balldontlie.io`	BALLDONTLIE API base URL
`API_TIMEOUT`	`30000`	Upstream timeout in milliseconds
`ENABLE_DEBUG`	`false`	Logs only method, query-free path, and query-field count
`ENABLE_SENSITIVE_ACCOUNT_TOOLS`	`false`	Enables sensitive Account tools only when exactly `true`
`TRUST_PROXY_HOPS`	`1` in production, `0` otherwise	Validated trusted proxy hop count; only `0` or `1` is accepted
`ENABLE_TRACING`	`false`	Enables Datadog tracing when an agent host is configured

Authorization values, query values, request bodies, raw upstream errors, API-key responses, and hosted billing-session URLs are excluded from server logs and tracing tags.
