About Gyazo MCP Server

A local MCP (Model Context Protocol) server for Gyazo. Provides image listing, searching, uploading, deleting, and oEmbed metadata retrieval. Supports both streamable HTTP and stdio transports with MCP standard OAuth authentication.

What's new in 0.7.1

  • 保存済み OAuth token の access_token が空文字になっている場合に有効なトークンとして読み込んでしまい、Gyazo API (users/me) への疎通確認が常に 401 Unauthorized で失敗する不具合を修正しました。load_token で空文字を未認証として扱うようにしました。
  • /token エンドポイントの失敗レスポンスを RFC 6749 準拠の JSON エラー形式 ({"error": "...", "error_description": "..."}) に変更しました。従来はプレーンテキストで返していたため、クライアント側の OAuth エラーパーサーが JSON パースに失敗し、本来の失敗理由が埋もれてしまう問題がありました。

Inkscape

Inkscape 1.4.4

Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. In contrast to raster (bitmap) graphics editors such as Photoshop or Gimp, Inkscape stores its graphics in a vector format. Vector graphics is a resolution-independent description of the actual shapes and objects that you see in the image. A rasterization engine uses this information to determine how to plot each line and curve at any resolution or zoom level. Contrast that to bitmap (raster) graphics which is always bound to a specific resolution and stores an image as a grid of pixels. Inkscape can import and display bitmap images, too. An imported bitmap becomes yet another object in your vector graphics, and you can do with it everything you can do to other kinds of objects (move, transform, clip, etc.) While Inkscape does not have all the features of the leading vector editors, the latest versions provide for a large portion of basic vector graphics editing capabilities. People report successfully using Inkscape in a lot of very different projects (web graphics, technical diagrams, icons, creative art, logos, maps).
