- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_credit_balance (destructiveHint, idempotentHint); get_image_sizes (destructiveHint, idempotentHint); ai_extend_image (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 805 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 6 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 805 tokens to load them all
- tool set hash: 3fbd3adb84293b29bb963e7b4a0850b4
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.geektao1024/cropden.svg)](https://protogrid.dev/servers/io.github.geektao1024/cropden)

## Tools (6)

- `ai_extend_image`: Extend an image to a wider or taller shape with AI, e.g. a portrait photo to a 16:9 YouTube thumbnail without cropping the subject. Costs 5 CropDen credits per run, refunded if it fails. Needs a CropDen API key. Input: PNG, JPEG or WebP, up to 10 MB and 2048 px on the longest side. Returns a link to the result, valid 7 days. The model redraws the whole frame, so tiny details of the original can change.
- `ai_remove_background`: Remove the background of an image with AI; the result is a PNG with transparency. Costs 1 credit per run, refunded if it fails. Needs a CropDen API key. Input: PNG, JPEG or WebP, up to 10 MB and 2048 px on the longest side. Returns a link to the result, valid 7 days.
- `ai_upscale_image`: Upscale an image 2x or 4x with AI. Costs 8 credits for 2x and 12 for 4x, refunded if it fails. Needs a CropDen API key. Input: PNG, JPEG or WebP, up to 10 MB; longest side up to 2048 px for 2x or 1024 px for 4x. Returns a link to the result, valid 7 days.
- `get_ai_task`: Status of an AI run that was still working when its tool returned. Pass the task_id it gave you; wait about 10 seconds between checks.
- `get_credit_balance`: How many CropDen credits the API key owner has left.
- `get_image_sizes`: Exact image sizes for Instagram, YouTube, TikTok, X, LinkedIn, Facebook, Discord, Twitch, Pinterest, marketplaces and passport photos, with safe zones (pixel areas the app covers or crops), upload limits and minimum sizes. Free, no API key. With no arguments it lists every size id; pass `id` (e.g. "youtube-banner/banner") or `platform` (e.g. "Instagram") for full details.
