    How to connect

    How to connect CompatAir to Claude

    The server address to paste into Claude settings:

    https://compatair.fr/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 CompatAir to ChatGPT

    The server address to paste into ChatGPT settings:

    https://compatair.fr/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.

    orient_decisionRoute a pneumatic-air question to the smallest suitable CompatAir tool and profile. Use this when the next action is unclear.
    evaluate_air_compatibilityEvaluate documented air-supply compatibility for one compressor and one or more tools. Returns air-supply and complete-system verdicts separately; commercial data never changes either verdict.
    identify_productIdentify a catalog product from a name, CompatAir or merchant URL, EAN/GTIN, MPN, evidenced distributor SKU, reference, or stable CompatAir ID. No network fetch is performed.
    build_complete_air_systemBuild a source-backed compressor, pneumatic tool, hose, connector, filtration and lubrication system. The complete-system verdict remains insufficient_data until real network pressure loss is verified; missing component data stays explicit.
    find_compatible_alternativesFind the smallest verified compressor substitution for an incompatible documented system. Commercial commission never affects ordering.
    search_knowledgeSearch the published CompatAir guides, glossary, methods and product pages. The server never fetches arbitrary external content.
    get_current_offersReturn dated current prices and availability separately from technical verdicts. Only allowlisted, fresh merchant destinations are returned.
