micompress-mcp

An MCP server that lets AI agents compress images, PDFs, video, audio, documents & archives. Powered by micompress.com.

Ask your assistant "compress the screenshots in ./assets" and it will — no manual upload, no separate tool. Works with any Model Context Protocol client: Claude Desktop, Claude Code, Cursor, and others.

Setup

Claude Code

claude mcp add micompress -- npx -y micompress-mcp

Claude Desktop / Cursor

Add to your MCP config (claude_desktop_config.json on Desktop):

{
  "mcpServers": {
    "micompress": {
      "command": "npx",
      "args": ["-y", "micompress-mcp"]
    }
  }
}

Tools

compress_file

Compresses a file and writes the smaller version to disk.

Input

Description

path (required)

File to compress

output_path

Where to write it. Defaults to the input path with a -min suffix. Pass the input path to overwrite in place.

preset

lossless · recommended (default) · extreme

max_width

Images only — resize down to this width in pixels

Returns the size before and after, plus the output path. The file bytes are never returned to the model — only the summary, so a large file can't flood the context window.

list_supported_formats

Lists every accepted extension, grouped by category.

How it works

Files are uploaded over HTTPS to micompress.com and compressed with the same engine the website uses (mozjpeg, pngquant, gifski, Ghostscript, ffmpeg, …), then written back to disk. Anonymous use works within per-type size limits (images 20MB, video 50MB, …).

Point it at files you're comfortable sending to a third-party service. The agent passes a path; the file's contents leave your machine.

Requirements

Node.js >= 18
