Common questions
Is Posy safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 23 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

What is Posy
Posy is a link-in-bio page that looks hand-made. You pick a look, add your links, and publish. Edit it yourself in a calm studio, or ask your AI to do it for you. Your page is one small JSON file you can take anywhere.
The looks
The same links, drawn as a wooden desk with polaroids, a Japanese print, a desktop left open, a watercolour, a two-ink print or a netrunner's screen. Each look has four palettes, and you can switch any time.
On posy.page, Painted, Desk and Lofi are free, and the others come with Pro. Self-hosted, every look is unlocked. See them live in the looks gallery.

Connect your AI
Posy has a hosted MCP server, so your AI can make and edit your page. You sign in with your Posy account; there is no key to copy. Everything it does lands in your draft, and nothing goes live until you, or it, publish.
