Two commands install the plugin: the crado MCP server plus the skills that keep a page working inside crado's sandbox. Then verify with claude mcp list — crado should show as connected.
claude plugin marketplace add crado-ai/claude-plugin claude plugin install crado@crado
# ~/.zshrc or ~/.bashrc — before launching Claude Code export CRADO_API_KEY="YOUR_KEY"
claude mcp add --transport http crado https://crado.ai/mcp \ --header "Authorization: Bearer YOUR_KEY" --scope user
Claude Code ships an Artifact tool that publishes pages to claude.ai. Its schema costs roughly 20k tokens in every session, and with crado installed publish_page does that job. A plugin cannot change your settings, so add this to ~/.claude/settings.json yourself.
{ "permissions": { "deny": ["Artifact"] } }There is also "enableArtifact": false. It works, but once set in any settings file no other settings file can turn the tool back on — prefer the deny rule.
