tmphost: an open-source ephemeral file host and MCP server born from a Claude artifacts mishap
hasmcp · reddit · 2026-10-20
The author asked a remote Claude instance to share a design; it landed in Claude artifacts, but he was logged into another team account and couldn't view it. So he built tmphost.io — a free, open-source ephemeral static file host for agents, with a remote MCP endpoint at mcp.tmphost.io/mcp.
Agents can upload generated files and get shareable temporary links, avoiding account/platform lock-in. Source is on GitHub at tmphost/tmphost.
