What is the Gyazo MCP server?

Most developer tooling work still happens through a UI a human drives. Gyazo MCP server moves it into the conversation instead. Model Context Protocol (MCP) server for Gyazo API integration - Upload images, list, retrieve, and manage your Gyazo screenshots.

The tools it exposes

The server publishes 9 tools. What each one is for:

  • upload_image — Upload images to Gyazo
  • list_images — List your uploaded images
  • get_image — Get detailed information about a specific image
  • delete_image — Delete an image from Gyazo
  • get_oembed — Get oEmbed information for a Gyazo image URL
  • Tools — The Tools tool exposed by this server
  • Resources — The Resources tool exposed by this server
  • Standalone — The Standalone tool exposed by this server
  • Build — The Build tool exposed by this server

What it needs from you

Configuration is passed through the environment: GYAZO_ACCESS_TOKEN, YOUR_PROJECT_ID. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Getting it running

@mercy34mercy/gyazo-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

How it compares

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Gyazo's toolset — upload_image, list_images, get_image and 6 more — is a fair guide to whether it matches your workflow. It is maintained by mercy34mercy; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 9 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Gyazo.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
