mcp-server-invokeai¶

An MCP server for InvokeAI image generation: text-to-image, image-to-image and upscaling against a local InvokeAI instance. Companion package: mcprack-mcp-server-invokeai. Binary: /usr/bin/mcp-server-invokeai.

sudo apt install mcprack-mcp-server-invokeai

Configuration¶

Variable	Required	Meaning
`INVOKEAI_BASE_URL`	no	InvokeAI REST API (default `http://127.0.0.1:9090`)
`INVOKEAI_READ_ONLY`	no	`true` registers only the read-only tools
`INVOKEAI_UPLOAD_ROOT`	no	`:`-separated directories from which `img2img` and `upscale_image` may read local files (default `$HOME` and the temp directory)

Registration:

sudo mcprack server show mcp-server-invokeai
sudo mcprack server edit mcp-server-invokeai --add-secret-key <SECRET_VARIABLE>
sudo mcprack secret set mcp-server-invokeai <SECRET_VARIABLE>

Replace <SECRET_VARIABLE> with each secret variable from the table.

Read-only behaviour: INVOKEAI_READ_ONLY=true hides all image-creating tools.

Tools¶

Read-only: list_models, get_queue_status.
Creating (not idempotent): generate_image, img2img, upscale_image.
