    How to connect

    How to connect UpgradeLens to Claude

    The server address to paste into Claude settings:

    https://upgradelens.mattpicone.workers.dev/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 UpgradeLens to ChatGPT

    The server address to paste into ChatGPT settings:

    https://upgradelens.mattpicone.workers.dev/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.

    review_dependency_upgradeUse when an agent reviews a Dependabot, Renovate, npm, or PyPI version change before merge. One cited result combines security delta, runtime compatibility, breaking changes, go/no-go risk, and ordered migration actions for exact current and target versions. Do not use for new installs, unknown versions, general documentation, or other ecosystems. Read-only and safe to retry.
    check_dependency_upgradeUse when a coding agent needs a cited go/no-go risk decision without steps before changing an existing npm or PyPI dependency between two exact versions. Returns action_allowed, vulnerability delta, compatibility, EOL, and breaking-change evidence. Use plan_dependency_upgrade instead for ordered migration work. Do not use to choose a target, install a new package, search general docs, or analyze another ecosystem. Read-only and safe to retry.
    find_safe_upgrade_targetUse only when an existing npm or PyPI dependency has an exact current version but no chosen target. Ranks candidates; candidates are not declared safe and require check_dependency_upgrade or plan_dependency_upgrade. Do not use when a target is stated, for a new install, or as authorization to edit files. Read-only and safe to retry.
    plan_dependency_upgradeUse when a coding agent needs a migration checklist, refactor actions, ordered review actions, changelog links, or test steps for exact current and target npm/PyPI versions. Use check_dependency_upgrade instead for a go/no-go without steps. Do not use to choose a target, install a package, or provide a general tutorial. Read-only and safe to retry.
