Upload local assets (images, mockups, HTML, and markdown files) to a Stitch project using the provided upload script, which bypasses the MCP tool's base64 output token limits. [!NOTE] The AI model cannot upload files via MCP tools directly because the base64 encoding of even a small file exceeds the model's output token limit (16K tokens). This script reads the file and sends it directly over HTTP. Use listprojects to find the correct projectId. Locate your active MCP server configuration file and extract the API key: Antigravity: .gemini/antigravity/mcpconfig.json or .gemini/jetski/mcpconfig.json Gemini CLI: /.gemini/settings.json or /.gemini/extensions/Stitch/gemini-extension.json Claude Code: /.claude.json Extract: API Key: From the X-Goog-Api-Key header or auth argument MCP URL (optional): From the httpUrl or endpoint argument (defaults to https://stitch.googleapis.com) [!IMPORTANT] If you cannot find the API key in any of these locations, or if you cannot access these files, you MUST ask the user to provide the Stitch API key. Do not proceed without a valid API key. [!WARNING] Checkpoint — User Confirmation Required. Before running the upload script, you MUST pause and present
