Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Convert format and/or compress an image. $0.005 per call. Input: an image via source URL. Params: format (webp|avif|jpeg|png|gif); quality (1-100, default 85 — lower is smaller). At least one of format/quality is required. Output: the optimized image as a short-lived signed URL.
Public https:// URL of the source image to process.

}Apply an ordered pipeline of image ops in a single paid call: one payment, one output. Price is the sum of the included ops’ prices — call without payment to get a 402 quote. Input: source (image URL), steps (ordered [{op, params}], e.g. [{"op":"remove_background"},{"op":"resize","params":{"width":800}}]). Call service_info for the available ops and their per-op prices. Output: the processed image as a short-lived signed URL.

}Remove an image's background, isolating the subject (BiRefNet AI segmentation). $0.02 per call. Input: an image via source URL. Params: background (optional fill color for the removed area, e.g. 'white'; omit for a transparent cutout — use a PNG/WebP output to keep transparency). Output: the cut-out image as a short-lived signed URL.

}Resize or crop an image to an exact width/height. $0.005 per call. Input: an image via source URL. Params: width, height (pixels); fit (scale-down|contain|pad|squeeze|cover|crop); gravity (auto|face|left|right|top|bottom|center|entropy — focal point for cover/crop, use 'face' to keep faces); background (fill color for 'pad', e.g. 'white' or 'rgba(0,0,0,0)' for transparent). At least one of width/height is required. Output: the transformed image as a short-lived signed URL.
