FAQ from DALL-E MCP Server

Which DALL‑E models does the server support?

The server supports DALL‑E 2 and DALL‑E 3. DALL‑E 3 offers hd quality and vivid/natural style options; DALL‑E 2 supports image editing and variations.

How do I configure the server for use with Cline?

Add a dalle-mcp entry to your Cline MCP settings JSON with command, args pointing to the built index.js, and env containing OPENAI_API_KEY and optionally SAVE_DIR. For Cline to display images, set saveDir to the current workspace directory.

What are the limitations of edit_image?

As of March 18, 2025, the DALL‑E 2 edit API may ignore the prompt and return the original image. If that happens, try using create_variation instead, which appears more reliable.

How do I validate my OpenAI API key?

Use the validate_key tool with no parameters. It returns whether the API key is valid.

Where are generated images saved by default?

Images are saved to the current directory or the directory specified by the SAVE_DIR environment variable. You can override this per‑tool with the saveDir parameter.
