# Stow

> Quick public file storage for people and their agents. Upload a file, get a
> public, unguessable URL on stow.sh, and resize images and videos with query
> parameters. Personal is $5 a month for 10 GB; Studio is $15 a month or $150 a
> year for 100 GB. Files up to 100 MB.

Reads are public and need no auth. Writes need an API key from
https://stow.sh/account, or an MCP client signed in through OAuth. Give users
the returned URL exactly as it comes back.
