Authenticate first by calling authenticate(api_key), or pass rd_api_key directly on each tool call. For the highest quality stills prefer RD Pro styles (rd_pro__*); they support per-inference reference_images (up to 9) for character/style consistency, and most (rd_pro__default, painterly, fantasy, horror, scifi, simple, isometric, topdown, platformer) go as small as 12x12 px for tiny sprites and icons, and rd_pro__pixelate converts an input_image down to 16x16 px — check list_available_styles for each style's exact limits. To animate an existing sprite prefer the advanced animation styles (rd_advanced_animation__walking/idle/jump/crouch/attack/destroy/custom_action/subtle_motion) started via start_inference_job and polled with get_inference_job — animations are long-running. rd_advanced_animation__rotate turns one sprite into its 8 directional views instead of motion (prompt optional, frames_duration ignored; GIF by default, return_spritesheet=true for the 3x3 direction sheet). Use fix_pixel_art on enlarged, softened, or AI-rendered pixel art to recover its native pixel grid. Post-process results with run_edit_tool: background_remover, color_style_transfer are $0.01; color_reducer, palette_converter, pixel_correction, k_centroid_downscale, rotate are free; image_edit, inpainting, outpainting, seam_tiling are premium. Before create_inference, use list_available_styles or get_style_usage(prompt_style) to confirm whether you should send input_image, per-inference reference_images, or style_reference_images. create_inference returns hosted output_urls and a request_id; if delivery is pending, call get_inference_result(request_id) and never repeat the paid generation automatically. estimate_inference_cost and estimate_edit_tool_cost are always free — check prices before spending.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

create_inference unknown never probed

Generate images using the public /v2/inferences endpoint. For the highest quality prefer RD Pro styles (rd_pro__*); they support reference_images for character/style consistency, and most go as small as 12x12 px (check list_available_styles for each style's limits) — a small target size is never a reason to switch to a cheaper model family. Style ids are opaque strings with no uniform format (some RD Fast styles appear as "default:rd_flux"); take them verbatim from the catalog and never infer capabilities from an id's prefix. For animation styles prefer start_inference_job + get_inference_job instead — animations are long-running, and a failed animation is worth one retry with identical parameters (failures auto-refund). Field-tested workflow rules: N distinct items = N individually usable images (separate calls or num_images=N), never one sheet/grid image unless a sheet IS the deliverable. Variants of ONE image (seasons, day/night, palettes) = generate the base once, then derive each variant with the image_edit tool ("... keep the exact same composition") — independent generations of the "same" scene come out unrelated. Converting an existing image INTO pixel art is rd_pro__pixelate with input_image (16-256 px output, batch<=16); reference_images-based generation re-imagines rather than converts. To animate an image you already have, use rd_advanced_animation__* with input_image (fixed-format rd_animation__* styles generate their own subject from the prompt instead). To get the other directional views of a sprite you already have, use rd_advanced_animation__rotate with input_image (same 8-direction layout as rd_animation__8_dir_rotation). Use `input_image` for the main source image, `reference_images` for extra per-inference guidance, and `style_reference_images` only on create_user_style/update_user_style. The response excludes raw base64 image payloads to keep MCP outputs compact.

fix_pixel_art unknown never probed

Recover the native pixel grid from enlarged, softened, AI-rendered, or compressed pixel art. Standard uses the native Rust detector. Neural uses the neural reconstruction engine and accepts optional target width and height values. This repairs existing art—it does not generate a new image. Both engines are free and share a limit of 10 requests per minute per API token. Provide exactly one source as base64 input_image or a public HTTPS image_url. URL input avoids the ALB request-body limit. Decoded images may contain up to 16 megapixels. Successful response JSON is limited to 850,000 bytes for AWS ALB compatibility.

run_edit_tool unknown never probed

Run a canvas edit tool on an image via /v2/edit/tools/{tool_id}. Free tools: color_reducer, palette_converter, pixel_correction, k_centroid_downscale, rotate. $0.01 tools: background_remover, color_style_transfer. Premium ($0.18): image_edit, inpainting, outpainting, seam_tiling. Use estimate_edit_tool_cost first for anything that charges — estimation is free. The edited image is returned in base64_images.

get_inference_result unknown never probed

start_inference_job unknown never probed

Start a generation as an async job (POST /v2/inferences with async=true) and return a task_id. Recommended for advanced animations (rd_advanced_animation__*), other animation styles, and batches — they run for tens of seconds and can outlive a synchronous MCP call. Poll the returned task_id with get_inference_job roughly every 2-5 seconds.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
