Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Gyazo Memory CLI for AI Secretary.

Install

npm i -g @yuiseki/gyazocli

Usage

gyazo config set token your_personal_gyazo_access_token_here
gyazo sync --days 10
gyazo --help

Shorthands

The first argument may stand on its own when it is unambiguous. A Gyazo image ID is 32 hex characters, so it can never be mistaken for a path.

gyazo path/to/image.png                              # same as: gyazo upload path/to/image.png
gyazo 49a008e2f254f513063b6ec4d3082940               # same as: gyazo get 49a008e2f254f513063b6ec4d3082940
gyazo https://gyazo.com/49a008e2f254f513063b6ec4d3082940   # same as above
gyazo https://gyazo.com/collections/21ca16a1023c667a7a437be561a65018  # same as: gyazo collection 

A collection ID is 32 hex characters just like an image ID, so a bare ID is read as an image. Only the /collections/ URL form is unambiguous. When a command is given the wrong kind of ID it points at the other one.

Subcommand names always win, so gyazo search stays gyazo search even if a file of that name exists in the working directory.

Detail

  • gyazo config set token : Save your access token
  • gyazo config get token|me: Show saved token (masked) or me profile info
  • gyazo ls (gyazo list): List images (--date/--today, --photos, --uploaded, -H available; --photos/--uploaded can be combined with --date/--today)
  • gyazo search : Search images
  • gyazo collection (col, cols, collections): Show a collection and the images in it (--sort added|created|captured, -A, -j available). --ids prints just the image IDs, one per line, to pipe into restore; with cookies (the default lookup or --cookies ) it reads the real IDs even for withheld images
  • gyazo get : Show image details (--ocr, --objects, -j available). Accepts a bare image ID, a https://gyazo.com/ permalink, or a `https://i

Questions

What is the gyazocli MCP server?

Fast, script-friendly CLI for Gyazo

What tools does gyazocli expose?

9 in total: 9 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is gyazocli safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does gyazocli need?

It reads GYAZO_ACCESS_TOKEN and GYAZO_CLIENT_SECRET from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does gyazocli run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as @yuiseki/gyazocli at 0.11.0.

How current is this page?

The grade is for one exact copy of the source (410e926bb99a), read on 2026-10-10. The repository is watched and re-audited when it changes.
