    How to connect

    How to connect Money Mind — the judge to Claude

    The server address to paste into Claude settings:

    https://money-mind-extract.onrender.com/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect Money Mind — the judge to ChatGPT

    The server address to paste into ChatGPT settings:

    https://money-mind-extract.onrender.com/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    check_price_dataFREE, no payment or account. Audits OHLC bars for the defects that silently invalidate a backtest. Free and indicative feeds often SYNTHESISE the bar's open instead of observing it, which pins |open-close|/range near zero — measured on the same FX pairs, a free feed reads 0.020 against a real broker's 0.464. Anything depending on the open (gap trades, overnight holds, next-bar entries) is invalid on such data. Also detects frozen zero-range bars, duplicate and out-of-order timestamps, and bars whose high/low do not bracket open/close. Returns BROKER-GRADE, SUSPECT or INDICATIVE with the numbers behind it. Use this BEFORE trusting any backtest built on the data.
    check_eval_selectionFREE. Use after picking the best of several prompts, models, configs or hyperparameters. Keeping the top scorer out of N is SELECTION: the winner's score is inflated simply by having looked N times, and every eval harness reports it as though one experiment were run. Give the score each variant achieved and it returns how much of the winner's margin the search itself explains, what pure noise would have handed you, and whether the excess is real. Supply n_per_variant to also learn whether your variants can be told apart at all. Call this before concluding an optimisation found something.
    factcheckVerify a claim against 2-4 source URLs: cited passages, cross-source agreement, verdict: consistent | conflicting | insufficient_evidence. Evidence, not truth. Use when your agent needs to verify a claim against independent sources before acting on it. Give a claim plus 2-4 source URLs; each source is extracted (three-fetch cross-check, confidence-scored), the checkable figures are compared across sources, and you get the cited passages plus a verdict: con PAID: $0.03 USDC on Base via x402.

    v1_extractFetch a web page three independent ways (rendered, static, second-render cross-check), confidence-scored, with a tamper-evident attestation. Refuses protected, login and CAPTCHA pages without charging. Use when your agent needs web content it cannot fetch itself — JavaScript-rendered pages, static pages, or paginated listings — and needs to show its principal the evidence.
