MCP server for horizOn Backend-as-a-Service
Gives AI coding assistants documentation, live API tools, and workflow prompts for game and app development.
Add to your MCP client configuration (Claude Desktop, Cursor, etc.):
{
"mcpServers": { "horizOn": { "command": "npx", "args": ["-y", "horizon-mcp"], "env": { "HORIZON_API_KEY": "your-api-key-here" } } } }
The server exposes 29 documentation resources, 120 player tools and 4 workflow prompts. An Account Key enables additional scoped admin tools. These counts come from the registered MCP resources, tools and prompts.
Documentation resources are served directly from the MCP server. No API key required.

Live API tools that call the horizOn backend. Requires a valid API key.
horizon_submit_score, horizon_save_cloud_data, horizon_load_cloud_data, horizon_prepare_gift_code, horizon_redeem_gift_code, horizon_get_profile, horizon_set_profile, horizon_start_run, horizon_submit_validated, horizon_get_state and horizon_upload_evidence also need the player's session: sign in first and pass the returned accessToken as sessionToken.
The four player-value tools also require the same player session. Never generate another operation ID automatically after an uncertain result.
Every tool declares MCP annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint), so clients can tell reads from writes. Examples of destructive tools include horizon_save_cloud_data (replaces the save), horizon_set_profile (replaces the whole profile), horizon_submit_validated (consumes the ticket, can spend balances) and horizon_cancel_email, plus horizon_purchase_player_value_offer and horizon_adjust_player_value (debit or credit exactly once per persisted operation ID). Many read tools that return an object also declare an outputSchema and return structuredContent next to the JSON text. Each description names when to use the tool, which sibling to use instead, what it returns and how to recover from its errors.
