## What it does

This server links your development agent with pastehtml.dev over HTTP. Whenever the model creates markup files up to 2 MB, it uploads them to dedicated subdomains and returns live URLs alongside source inspection pages. Each paste runs on its own isolated origin, allowing local storage and client scripts to work safely.

Communication uses the remote endpoint at `https://pastehtml.dev/mcp`. You do not need to configure static tokens in project configs: the client authenticates via a browser consent screen through OAuth on initial execution. After granting access, uploads map directly to your account folders and tracking dashboard.

Keep in mind that pastes cannot be deleted once created on the platform. The service only permits in-place overwrites to replace file bytes while preserving the existing link.
