Tools & capabilities
Glassypic tools 5
optimize_imageOptimize an image: smart lossy compression (typically 60-80% size reduction), optional resize/upscale/format conversion, and AI-generated SEO metadata. Accepts absolute local file paths or remote URLs. In remote/API mode, only remote URLs are supported. Supported input formats: JPG, PNG, WebP, AVIF, GIF, SVG, ICO, HEIC, TIFF, BMP (max 50 MB). Supported output formats: JPG, PNG, WebP, AVIF, GIF, SVG, ICO. Credits: 3 to compress (always), +1 if width or height is set, +2 to upscale, +1 for SEO tags (on by default). A full pipeline is 7 credits. Upscale is charged whether you request it or the server adds it automatically — it does so whenever a resize target exceeds the source by more than 1.2x, so a resize-only call on a small image also costs 7. SVG or ICO output is a flat 1 credit, overriding everything above. Animated GIFs are billed per frame: (per-frame operations x frames) + 1 if tags, up to 601 credits at the 100-frame limit — confirm_gif_cost gates that path. GIFs are excluded from automatic upscaling. Guest (unregistered): 20 credits/day, no signup. Log in with the login tool for more credits — registered Free tier is 30/day. Use status tool to check remaining credits before batch processing.loginLog in to your GlassyPic account via browser to unlock more credits. Opens a browser window where you complete login (Google, Facebook, or email). After login, MCP automatically picks up your account with shared credits across web and MCP. Registered accounts receive a larger credit allowance than guest sessions; use the status tool to read the account's actual tier and remaining credits. Your access token and email are stored locally at ~/.glassypic/session.json (file mode 0600) until you run logout.logoutLog out of your GlassyPic account. Reverts to guest session (20 free credits/day). Your web app account is not affected.statusCheck your GlassyPic account status: login state, tier, credits remaining, and credit reset time. Use this before batch processing to verify sufficient credits.upgradeOpen the GlassyPic pricing page in the user's browser, where the account's plan can be reviewed and changed.
