@scenar/mcp-server

The Model Context Protocol server for Scenar — it lets AI editors (Cursor, Claude Desktop, etc.) bootstrap a demos project, author a scenario tour, narrate it, pack it, and serve or publish the embed. A thin, type-safe wrapper over the @scenar/cli programmatic API.

Install in Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "scenar": { "command": "npx", "args": ["-y", "@scenar/mcp-server"] }
  }
}

Then add the bundled authoring skill so the model knows the scenario model:

mkdir -p .cursor/skills
cp -R node_modules/@scenar/mcp-server/skill .cursor/skills/scenar

Restart your editor.
