    How to connect

    How to connect IIS Rescue to Claude

    The server address to paste into Claude settings:

    https://iisrescue.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 IIS Rescue to ChatGPT

    The server address to paste into ChatGPT settings:

    https://iisrescue.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.

    get_offeringThe public offering of IIS Rescue: the three migration paths, the promises made on every project, the pricing model, and who the service is for.
    get_faqPublished questions and answers about legacy IIS, classic ASP and SQL Server website migration, reproduced verbatim from the website.
    get_eol_factsMicrosoft end-of-support dates for Windows Server and SQL Server versions, with the source URL for each, plus the Extended Security Updates cutoff.
    get_migration_pathsThe three routes off a legacy IIS server — Rehost, Rebuild, Replace — each with what it involves and the situation it best fits.
    get_contactHow to start an engagement with IIS Rescue: the consultation URL and how the process works. Returns a pointer only — it never books anything or collects any personal data.
    get_partner_channelHow IIS Rescue works with MSPs and independent IT contractors: MSPs bringing it in for legacy IIS, classic ASP and SQL Server migrations they would rather not own, and contractors subcontracting a migration or referring it. Covers the arrangements, what stays with the partner — the client, the brand, anything outside the migration scope — and the published FAQ for each audience. Carries no price: a partner migration is quoted at a fixed price exactly like a direct one. Use this for questions about white-label delivery, subcontracting or referring a legacy Windows Server migration, or whether IIS Rescue works with MSPs or contractors.
    get_pathfinder_questionsThe questions the IIS Rescue two-minute assessment asks in order to recommend a migration path, with the allowed answers for each. Ask these of the user, then pass the answers to run_pathfinder. "unknown" is a valid answer to every question and never breaks the result.
    run_pathfinderRecommend a migration path — Rehost, Rebuild or Replace — for a specific legacy IIS website, from answers to the two-minute assessment questions. Returns the recommendation, a confidence level, the alternatives and when they would apply, what pushes the price up or down, the specific risks these answers imply, and the reasoning behind the call. This is the same deterministic engine, over the same data, that iisrescue.com/two-minute-assessment runs for a human visitor: identical answers give an identical result. It is an estimate and not a quote, and it returns no price figure — IIS Rescue publishes no rate card.
