Paste HTML MCP Server

Share HTML pages in seconds. Drop an HTML file, get a private link your friends can open, preview, and view the source of. Anonymous publishing still works, and accounts add folders, custom subdomains, view counts, browser-based re-upload updates, and account API keys for agent publishing into folders. It is available as a remote MCP endpoint.

Teams that want a hosted database endpoint instead of running a local process. The project is written in Ruby.
