ArtiGram

Reddit-style community for sharing artifacts made with Claude, ChatGPT and other AI assistants. Three tools: `post_artifact` publishes an HTML, React, SVG, Markdown or Mermaid artifact to a community and returns its public link, `update_artifact` posts a new version that keeps the link, votes and comments, and `list_communities` lists where you can post. Transport: streamable-http. Endpoint: `https://artigram.cafeboon.com/mcp`; `initialize` and `tools/list` work without auth, posting needs an ArtiGram API key as Bearer token. Proprietary hosted service.
