How do I get a Riot Games API key?

Register at [**developer.riotgames.com**](https://developer.riotgames.com/) and sign in with your Riot account to get your personal development API key. It's free and works immediately.

PUUID (Player Universally Unique Identifier) is a unique ID assigned to every Riot account. It's required for most API calls like match history and champion masteries. Get it using get_account_by_riot_id with the player's game name and tag line.

What are platform codes?

Platform codes identify specific game servers: na1 (North America), euw1 (Europe West), eun1 (Europe Nordic & East), kr (Korea), br1 (Brazil), jp1 (Japan), la1/la2 (Latin America), tr1 (Turkey), oc1 (Oceania). Match history uses regional routing instead: americas, europe, asia, sea.

What are the API rate limits?

Development API keys are limited to 20 requests per second and 100 requests per 2 minutes. If you exceed these limits, the API returns a 429 error. Wait a moment and retry.

Riot Games + Cursor FAQ

Common questions about integrating Riot Games MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
