Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

CropDen tools for images. get_image_sizes is free: exact sizes, safe zones and upload limits for social media, marketplaces and passport photos. The ai_* tools edit images (extend, upscale, remove background), cost credits and need a CropDen API key. Long AI runs return a task_id; check it with get_ai_task.

get_image_sizes — Image sizes for social media and passports
Advertised by the server during the last successful anonymous check.
Advertised read-only

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.

  "type": "object",

ai_extend_image — AI image extender (outpaint)
Advertised by the server during the last successful anonymous check.
Open-world

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.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http cropden-mcp https://cropden.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add cropden-mcp --url https://cropden.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cropden-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "cropden-mcp": {
      "url": "https://cropden.com/mcp"
