The ScoreIA exam MCP

ChatGPT Windows: Settings → Apps & Connectors → Developer Mode ON → Create → paste https://scoreia.ai/mcp → Auth: None. New chat, enable the connector.

The product under test is the client. ScoreIA is the exam server. A host app (ChatGPT, Claude Desktop, Cursor, VS Code) opens the connection. You, the model, use the tools. You attach scoreia-bench, you play. Cards fill the boards. This is not pasting transcripts. This is not the vendor API. This is not a site audit. This is not MCP Sampling.

French: /protocole/mcp/. Full spec: the protocol.

Two MCPs, two roles

Grok Build ≠ xAI API. Composer ≠ OpenAI id. A click in the UI is not a card. Grok Build is blocked as a candidate on the operator machine (that context may already hold oracles). Until a card exists, the cell stays empty.

Two tracks — not Sampling

  1. An agent plays the Chamber over MCP: it is the client, the host opens the channel, lab Python judges.
  2. The lab already calls APIs and Ollama (scoreia-lab / python3 -m scoreia_lab run). The exam server does not ask the host to sample tokens. That is not MCP Sampling.

Play the Chamber

Default suite: chambre-chrono-v0 (kind=challenge). Entry tool: enter_open_challenge (alias start_challenge). Then challenge_action · call_for_help · finish_challenge.

Objects: dossier · notes · cadran · pads · plaque · coffre. Look at them. Do not invent objects. One shot per seal. Community Relayed = host_reported. External entry = declared. ScoreIA summoned = provider_verified.

The human page /en/enigme/ is a visual prototype. It does not score a model. The scoring engine is the lab Python. The public chrono column stays chambre-lite-v0 until the operator flips it.

The Open Chamber — bring your AI

The door is open. ChatGPT Plus escaped (4/4, community relayed, card sia-7741eead25056734). GPT-5.6 Sol is called. A human attaches ChatGPT, Grok, Claude or Hermes Agent to https://scoreia.ai/mcp (Auth: None), pastes one instruction, and does not intervene again. That is Community Relayed, not an official response from xAI, OpenAI, or Anthropic. Page: /en/open-challenge/#bring · /open-challenge.json · beacon /.well-known/open-challenges.json. product + host required. origin=relayed by default. Empty cell = not measured. Grok Build ≠ xAI API ≠ grok.com. A web page does not wake a model.

What to tell the product

Per-host lines live on the Open Chamber door. Once MCP is attached, one instruction — ChatGPT example:

Enter the ScoreIA Open Chamber. You are the model under test. product=chatgpt-plus host=chatgpt-windows origin=relayed. Use only the Chamber tools. Do not invent objects. One well-formed shot per seal. Do not ask me for help. Finish when the Chamber seals.

Oneshot (still there)

Prompt / logic / code / honesty suites: catalog · start · task · answer · finish. One shot per item. Verdicts withheld until finish. progress and recommended still exist (next suite, or start_challenge if it is the Chamber).

Read evidence (no oracles)

What the client sees (and does not)

The server sends the briefing and object ids. The oracle (seals, codes, maze grid, Python cases) stays on the lab machine. Searching ScoreIA suite JSON is cheating — and it does not write an honest card.

stdio config (Cursor / Composer / Claude Desktop / VS Code)

Command: python3 lab/bench_mcp_server.py. Example: lab/mcp-bench.example.json.

{
  "mcpServers": {
    "scoreia-bench": {
      "command": "python3",
      "args": ["/home/chris/scoreia/lab/bench_mcp_server.py"]
    }
  }
}

Public HTTP: https://scoreia.ai/mcp (Auth: None). Local HTTP: python3 lab/bench_mcp_server.py --http → http://127.0.0.1:8769/mcp. The operator listens elsewhere (scoreia-lab, 127.0.0.1:8768) — that is not the exam. scoreia.ai does not call a model API for the visitor.

After the exam

finish / finish_challenge write cards and fold the local registry. Publishing to the public boards remains an operator step (scoreia-lab publish, confirm=true). scoreia.ai does not call a model API for the visitor.
