CLAUDE.md

banana-image-mcp CLAUDE.md is an instructions file for Claude Code from zengwenliang416/banana-image-mcp. It costs 859 tokens per session, scanned A, original, MIT.

Project instructions for Banana Image MCP, a server that lets AI assistants generate and edit images through Google's Gemini models. MCP is a standard way for AI assistants to use external tools.

In plain words
What is it for?
Use them when developing or maintaining the image-generation server, including its model selection, image services, and error handling.
Why use it?
They explain the project's services, model choices, image settings, and architecture so coding agents can make changes in the right places.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

banana-image-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

This repository contains a production-ready Banana Image MCP Server - an AI-powered image generation and editing server that leverages Google's Gemini models through the FastMCP framework. The codebase implements a complete MCP (Model Context Protocol) server with modular architecture, comprehensive error handling, and production-ready features.

Key Capabilities

  • 4K Resolution: Up to 3840px professional-grade outputs
  • Google Search Grounding: Real-world knowledge integration for factual accuracy
  • Advanced Reasoning: Configurable thinking levels (LOW/HIGH) for complex compositions
  • Media Resolution Control: Fine-grained vision processing tuning
  • Intelligent Model Selection: Automatic routing based on prompt analysis

Architecture

  • ModelSelector: Service for intelligent model routing and selection logic
  • ProImageService: Dedicated service for Gemini 3 Pro Image operations
  • FlashImageService: Service for Gemini 2.5 Flash Image operations
  • BaseImageService: Abstract base class for image services
  • Multi-tier configuration: ModelSelectionConfig, ProImageConfig alongside existing GeminiConfig

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
