What is banana-image-mcp CLAUDE.md?

Repository instructions for an MCP server that generates blog cover images. They describe its image-generation, processing, cloud-upload pipeline and the settings needed to run it.

Use them when developing, configuring or debugging this blog-cover image server, including Gemini access, image compression, temporary files and uploads to Qiniu Cloud or Aliyun OSS.

They give a coding agent the project context, architecture and commands needed to make safe changes without guessing how image generation or storage works.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01450	$0.01450
Opus 5	$0.00725	$0.00725

Security

Grade B, and why

banana-image-mcp CLAUDE.md scanned grade B with 1 finding 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 10d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- JSON clients use `mcpServers`; Codex uses `~/.codex/config.toml` (`[mcp_servers.banana-image]`), edited via surgical block replace (preserves other sections/comments) with `smol-toml` for validation/detection

Project Overview

This is an MCP (Model Context Protocol) server that provides a tool for generating blog cover images. It integrates these services:

Google Gemini AI - Image generation from text prompts
Sharp - Image processing (resize, WebP conversion, compression)
Qiniu Cloud or Aliyun OSS - CDN storage for generated images (configurable via UPLOAD_PROVIDER)

The main export is generate_blog_cover() which orchestrates the full pipeline: generate → compress → upload → cleanup.

Architecture

MCP server (index.js):

Exposes three MCP tools: generate_blog_cover, generate_image, upload_image
Uses ES modules (import/export syntax)
Temporary files stored in system temp directory (os.tmpdir()/banana-image-mcp/)
File naming: YYYYMMDD-{slug}.webp
Two optional ways to reach Gemini: a forward proxy (undici setGlobalDispatcher for the SDK's global fetch; https-proxy-agent for axios downloads) via PROXY_URL, or a reverse-proxy gateway via GEMINI_BASE_URL + GEMINI_EXTRA_HEADERS (SDK httpOptions.baseUrl/headers)

Config wizard (cli-setup.js):

Loaded lazily when the binary is invoked as banana-image-mcp setup
Interactive readline prompts; multi-select one or more targets (Claude Code / Claude Desktop / Cursor / Codex / custom JSON path), writes/merges the banana-image entry into each, backing up existing files first
JSON clients use mcpServers; Codex uses ~/.codex/config.toml ([mcp_servers.banana-image]), edited via surgical block replace (preserves other sections/comments) with smol-toml for validation/detection

History (history-store.js + cli-history.js):

Every tool call is appended to ~/.banana-image-mcp/history.jsonl (time, tool, status, size, duration, url, error, model/aspectRatio/imageSize) via runWithHistory() in index.js — logging failures never break the tool
banana-image-mcp history renders a paginated, colorized table (columns: #, time, result, tool type, model, size, duration, url/error; latest first; ↑/↓ paging in a TTY)

Changes

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.
