Cleanor MCP
Zero-auth, hosted Model Context Protocol server for AI builders.
Two things no popular MCP does well, in one server:
- Actually optimize the images your AI just generated or a user dropped in (WebP / AVIF / JPEG, optional resize) — returns the smaller bytes plus before/after sizes.
- Hand back real, cited Cleanor Labs research data — device storage capacity, next-gen image-format savings, and the "HEIC conversion tax".
No API key. No signup. Every response links its source on cleanor.app.
- Endpoint (Streamable HTTP):
https://mcp.cleanor.app/mcp - Official MCP Registry:
app.cleanor/cleanor - Homepage: https://mcp.cleanor.app
Tools
| Tool | What it does |
|---|---|
optimize_image |
Fetch an image URL → re-encode smaller (WebP/AVIF/JPEG), optional resize. Returns the optimized image + before/after bytes. |
storage_capacity |
How many photos / minutes of video fit in a given GB tier, corrected for real OS/filesystem overhead. Backed by the photo-storage-capacity study. |
image_format_savings |
How much smaller WebP / AVIF / JPEG XL are than JPEG at matched quality, plus the HEIC → JPG/PNG conversion tax. From Cleanor's controlled benchmark. |
qr_code |
Text or URL → a crisp, dependency-free SVG QR code you can paste anywhere. |
All tools are read-only and safe to expose to autonomous agents.
Connect
Claude Code (CLI):
claude mcp add --transport http cleanor https://mcp.cleanor.app/mcp
Cursor (.cursor/mcp.json), Claude Desktop, VS Code, and most clients:
{
"mcpServers": {
"cleanor": {
"url": "https://mcp.cleanor.app/mcp"
}
}
}
Older clients that only speak stdio can bridge to the remote server with mcp-remote:
{
"mcpServers": {
"cleanor": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://mcp.cleanor.app/mcp"]
}
}

About
Built and hosted by Cleanor Labs — free, private, in-browser tools (files never leave your device) plus original research on device storage and image formats. The MCP server is a thin, hosted front door to that toolset and data for AI agents.
