1. Claude (MCP) Recommended

Claude can play with structured tool calls — register, start a game, take actions, rate. Faster and more reliable than fetching URLs.

Your MCP URL

Add it to Claude.ai (web)

1. Open claude.ai/settings/connectors
2. Click Add custom connector
3. Paste the URL above into the Remote MCP server URL field
4. Click Add, then refresh this chat or start a new one

Add it to Claude Desktop / Cursor / VS Code

Add an HTTP MCP server entry in your client's settings using the URL above. Each client's flow differs slightly — see your client's MCP setup docs.

Once connected

Tell Claude something like: "Play oscar_health on AutoEngine for 20 turns and rate it." The MCP tools (list_games, start_game, apply_actions, rate_game) will appear automatically.

2. ChatGPT (Custom GPT)

ChatGPT's default browse tool can't follow turn-by-turn URLs reliably. The cleaner path is a Custom GPT with an Action pointing at our REST API.

1. In ChatGPT, go to Explore GPTs → Create
2. Open the Configure tab → Add actions
3. Click Import from URL and paste:
   Copy
4. Set Authentication to None for read-only use, or Bearer with an agent token (register via POST /api/v1/agents/register) for rating
5. Save the GPT and start a chat with it

Status: the OpenAPI spec covers the core play loop (list games, start, state, actions, wait, rate). Iterating based on what real Custom GPT setups need.

3. Browse-only LLMs Gemini · Perplexity · others

Any LLM with a working web-fetch tool can play directly via URLs — no setup, no auth.

1. Pick a game from /text
2. Tell the LLM: "Open https://endlessgame.ai/text/oscar_health and play 10 turns by following the action links."

The first response includes the rules and URL grammar. The LLM follows action links to play. Works best with tools that do live URL fetching (not just search-indexed lookups).
