Frequently asked questions
How do I configure authentication for the WebUI?
Optionally set the `SD_AUTH_USER` and `SD_AUTH_PASS` environment variables if your WebUI instance requires basic authentication.
What tools does image-gen MCP Server provide?
It provides five tools: `generate_image`, `get_sd_models`, `set_sd_model`, `get_sd_upscalers`, and `upscale_images`.
How do I set up the server from source?
Clone the repository, run `npm install` to install dependencies, then `npm run build` to compile the server. Add the configuration to your MCP client with the required environment variables.
What common errors might occur and how can I fix them?
