• Project type: TypeScript Node.js MCP server using the official MCP TypeScript SDK and stdio transport.
• Primary references: https://github.com/modelcontextprotocol/typescript-sdk and https://ai.google.dev/gemini-api/docs/image-generation.
• Keep stdout reserved for MCP traffic. Send operational logs only to stderr.
• Persist local configuration in the hidden home file ~/.bigbananamcp.json and never print raw API keys.
• The local HTTP configuration service must stay bound to localhost by default.
• The main MCP tool should support text-to-image, image editing, multi-image fusion, search-grounded prompting, and context preservation with reference images.
