    How to connect

    How to connect AlpiX to Claude

    The server address to paste into Claude settings:

    https://alpix.alpic.ai

    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 AlpiX to ChatGPT

    The server address to paste into ChatGPT settings:

    https://alpix.alpic.ai

    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.

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
    3. Save the file. The server appears in the MCP list; authorize it there if asked.

    canvasOpen the live shared pixel canvas. Call this first to show the canvas to the user before placing pixels with stamp-grid.
    stamp-gridDraw a rectangular sprite on the shared 256x256 canvas by submitting an ASCII grid — the natural way to draw pixel art. Each line of the grid is one row of pixels; each character is one pixel. The grid's width and height set the drawing size. 'legend' maps single characters to palette color names. Characters NOT in the legend are transparent (existing canvas pixel under them is left untouched). The top-left of the grid is placed at (x, y) on the canvas. Coordinates: (0,0)=top-left, (255,255)=bottom-right. Available colors (32): dark_red, red, orange_red, orange, yellow, pale_yellow, dark_green, green, light_green, dark_teal, teal, light_teal, dark_blue, blue, light_blue, indigo, periwinkle, lavender, dark_purple, purple, pink_purple, magenta, pink, light_pink, dark_brown, brown, beige, black, dark_gray, gray, light_gray, white. Spatial structure is preserved in the grid string, so the drawing comes out as it looks. Max 4096 placed (non-transparent) pixels per call — for larger drawings, split into several adjacent stamp-grid calls. Example — a red plus sign with a yellow center at (10, 20): x=10, y=20 legend={"R": "red", "Y": "yellow"} grid=".R.\nRYR\n.R." (the '.' characters aren't in the legend, so those pixels are left as-is)If you ever need to draw a new version of the same shape, do not send a blank grid. Instead just draw above the existing shape. Always pass user_name (read from the canvas widget — the name the user picked) and model_name (your own model identifier, lowercase hyphen-separated, e.g. 'gpt-4o', 'claude-opus-4-7'). These are recorded so other users can see who drew it.
