    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.

    The server address to paste into ChatGPT settings:

    https://docs.osamahassouna.com/api/mcp

    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.

    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).

    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.

    Server tool list (4)

    Raw names from tools/list. Only developers need these.

    list_categoriesList all rule categories in the Email Playbook with a one-line description and page count. Categories are: structure (head/body container/header/body/footer), compatibility (Outlook MSO, RTL, responsive), production (Gmail clipping, dark mode, preheader, bulletproof buttons), ai-generation (constraints for AI emitters). For reusable components, use list_components instead — they live in a separate dimension and are not returned by get_playbook_rules.
    get_playbook_rulesReturn the full rule pages for a given category. Each rule includes the title, description, markdown body explaining the rule, and any HTML/CSS code examples from the playbook. Use this to teach a model the exact patterns for a specific concern (e.g., responsive layout).
    list_componentsList all reusable email components in the playbook with their metadata: name, subcategory (layout/media/interactive/text), description, whether they require Outlook VML, and whether they are responsive. Use this first to discover what components exist before calling get_component.
    get_componentReturn the full record for a single component: title, description, narrative body, the primary HTML pattern, list of slots (placeholders the model should fill), VML/responsive flags, and all code examples. Use after list_components to fetch the actual HTML pattern to paste into an email.
