Connects to Pixohub's image reference data. Muse can look up recommended dimensions and upload limits for social posts, marketplace listings and forms, suggest JPG, PNG or WebP for a destination, and explain what compressing a photo to a target file size will do.

Example request: "What size and file limit should I use for an Instagram story photo?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Pixohub to help me. It is a free service with an MCP server at https://mcp.pixohub.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- get_platform_image_size: Recommended image dimensions, aspect ratio, upload limits, cropping and safe zones for a social, video, marketplace or print placement (e.g. 'Instagram story', 'YouTube thumbnail', 'Etsy listing', 'LinkedIn banner'). Returns official-source quotes with check dates where available
- recommend_image_format: Recommends JPG, PNG, WebP, AVIF, SVG or GIF for a given image and destination, with the trade-offs and measured size change from Pixohub's conversion tests.
- find_upload_size_limit: Looks up official file-size and dimension limits for photo/document uploads: email attachments, government exam and visa forms, avatars, marketplaces (e.g. 'Gmail attachment', 'SSC photo', 'Discord avatar', 'US visa photo'). Returns the quoted rule, its source and a compress-to-s
- compression_advice: Given a target file size (KB) and optionally the image's current size and pixel dimensions, says what to expect when compressing to that size — quality, how much resolution is usually kept — based on Pixohub's measured tests on 44 photos, and links the matching compress-to-size t
- conversion_test_result: Returns Pixohub's measured result for converting between two image formats (e.g. png → webp, heic → jpg): output size change, fidelity (SSIM/PSNR), and whether transparency and EXIF survived.
