mcp-media-toolkit CLAUDE.md is an instructions file for Claude Code from kevinten-ai/mcp-media-toolkit. It costs 415 tokens per session, scanned A, original, MIT.

Instructions for an MCP server that processes images locally, including removing backgrounds, resizing, changing formats, searching stock media, and making collages.

In plain words
What is it for?
Use them when developing or maintaining image-processing features such as background removal, image conversion, resizing, and collage creation.
Why use it?
They explain how the image tools work, where files are saved, and what limits and safety rules apply.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md.

This is kevinten-ai/mcp-media-toolkit's own configuration. It tells Claude Code how to work on mcp-media-toolkit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-media-toolkit configures →

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

mcp-media-toolkit 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 9d 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.

What it actually says

CLAUDE.md — mcp-media-toolkit

Project Overview

MCP server for local image processing — background removal, stock media search, resize, format conversion, and collage creation. All tools are free and work locally (except Pexels search which uses a free API).

Architecture

  • Entry: src/media_toolkit/__init__.pyserver.main() via asyncio
  • Core: src/media_toolkit/server.py — all logic in one file
  • Libraries: Pillow (resize, convert, collage), rembg (background removal), httpx (Pexels API)

Key Design Decisions

  • All tools save output to IMAGE_OUTPUT_DIR (default: ./output) with timestamped filenames
  • rembg model (~170MB) downloads automatically on first use — no manual setup needed
  • output_path is optional on every tool — auto-generated if omitted
  • Custom outputs never overwrite inputs or existing files and must use the format's matching extension
  • Resource bounds: resize dimensions up to 8192px; collages up to 50 images, 20 columns, and 512px spacing
  • Collage canvases are capped at 40 million pixels; inline MCP previews are omitted above 5 MiB while saved files remain available
  • SVG→PNG conversion uses cairosvg if available, otherwise returns an error with install instructions
  • Pexels search requires PEXELS_API_KEY env var (free tier, no cost)

Development

uv sync                    # install deps
uv run media-toolkit       # run server

Common Pitfalls

  • First call to remove_background is slow (~30s) because rembg downloads the U2Net model
  • JPEG does not support transparency — convert_format auto-composites RGBA onto white background
  • Pexels API has rate limits (200 req/hour on free tier) — no auth = immediate error with helpful message
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.
