Original: How to host an app your AI built with its own URL and saved data
Short summary
Charming is an MCP connector that lets Claude host the apps it builds in-chat, giving each one a persistent URL and key-value storage. You add it as a custom connector in Claude, ask Claude to deploy, and it ships an ES module with manifest and route exports. Other MCP-capable agents can read and write the same app's data later, so the app survives beyond the original conversation.
- •Charming acts as an MCP connector so Claude can deploy in-chat apps to a live URL with storage
- •Apps are shipped as ES modules with route handlers backed by per-app key-value storage
- •Any MCP-capable agent can access the same app data after the original chat closes
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
