Pixel Art MCP server

What it does

A hosted remote MCP server that connects AI assistants to the Retro Diffusion API for generating grid-aligned pixel art including sprites, animations, and tilesets. It exposes tools for generation, editing, style management, and cost estimation, requiring only an API key and a Streamable HTTP-capable MCP client. Intended for developers and game artists who want to produce game-ready pixel art assets from within AI coding or chat environments.

• Generate a walking animation sprite sheet in a specific pixel art style by describing only the subject and letting the model handle rendering.
• Check the cost of a planned generation before committing credits using the free estimation tools.
• Recover the native pixel grid from an enlarged or softened pixel art image without re-generating or incurring additional charges.

Tools this server exposes

Tool	Does
create_inference	Generate images, animations (GIF or sprite sheet), or tilesets and return hosted URLs plus a recovery request_id.
get_inference_result	Retrieve or refresh signed output URLs for a completed synchronous generation without re-generating or charging again.
start_inference_job	Start a generation as an asynchronous job, recommended for animations and batch requests.
get_inference_job	Poll an async job by task_id to get its current status and results.
list_inference_jobs	List recent async jobs to recover a task_id after a lost submission response.
estimate_inference_cost	Return a free cost estimate for any generation before running it.
list_edit_tools	List the available post-processing edit tools with their fields, costs, and limits.
run_edit_tool	Execute an edit tool such as background removal, palette conversion, inpainting, or seam tiling on an existing image.
estimate_edit_tool_cost	Return a free cost and duration estimate for any edit tool operation.
fix_pixel_art	Reconstruct the native pixel grid from an enlarged, softened, or compressed pixel art image at no charge.
list_available_styles	Return the live catalog of pixel art styles with per-style size limits and capabilities.
list_available_models	List the available model families: RD Fast, RD Plus, RD Pro, and RD Mini.
get_style_usage	Return usage guidance and constraints for a specific style.
create_user_style	Create a custom style from a reference image using the RD Pro template.
update_user_style	Modify an existing custom style belonging to the authenticated user.
delete_user_style	Remove one of the authenticated user's custom styles.
authenticate	Validate an API key and attach it to the current session.
get_balance	Check the remaining prepaid balance and credit amounts for the account.
get_service_status	Return subsystem health status without requiring authentication.
logout	Clear the stored session API key.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
