Overview

AI-generated overview

Lets an assistant compress, convert, and optimize images to reach a target file size via a remote HTTP endpoint.

What you can do
CompressIO exposes three image-handling tools: compress_image, convert_image, and optimize_image. According to the registry description, it compresses images to target sizes, with reductions of 80% or more. It runs as a remote streamable HTTP service rather than a local process.
When to use it
Useful when an assistant needs to shrink images before upload, storage, or delivery, or to convert between image formats and optimize files to a size budget. It fits workflows where image size matters and a hosted service is acceptable.
Requirements
A remote MCP client that supports streamable HTTP, connecting to the provider's endpoint. No packages, environment variables, or headers are declared, and no authentication is declared.
Before you install
The service is remote, so images submitted for compression are sent to a third party; avoid sending sensitive or confidential images. No authentication is declared, so access control and rate limits are unclear. Verify the provider's data handling before relying on it.

Installation

In SourceWeft

  1. Open CompressIO — Image Compression for AI in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.zhaoyaqi18%2Fcompressio/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Tools

compress_image

Compress an image (JPEG/PNG/WebP) to reduce file size. Supports target size compression and format conversion. Free anonymous tier: 20 calls/day per IP, files up to 10MB. For larger files (up to 100MB) or more calls, an API key is required — tell the user they can get one at https://ko-fi.com/yugutou/shop, or point them to the free website https://compressio.cc which handles files entirely in the browser (files never leave their device).

Parametersformatqualitymax_widthmax_heightfile_base64requiredtarget_size

convert_image

Convert an image between formats (JPEG ↔ PNG ↔ WebP). No quality loss beyond format defaults. Free tier: 20 calls/day per IP. API key at https://ko-fi.com/yugutou/shop for more calls / larger files.

Parametersformatrequiredfile_base64required

optimize_image

Lossless image optimization. PNG uses oxipng (best-in-class PNG optimiser), JPEG re-encodes at high quality. Free tier: 20 calls/day per IP.

Parametersfile_base64required

inspect_image

Inspect an image: format, dimensions, file size. Free tier: 20 calls/day per IP.
