Frequently Asked Questions about MCP Server

Q: What is MCP Server?

A: MCP Server is a lightweight, dependency-free Node.js script that automates image compression using the TinyPNG API.

Q: What are the main benefits of using MCP Server?

A: The key benefits include dependency-free operation, duplicate compression filtering, MD5-based change detection, in-place file replacement, automatic API key rotation, compression reporting, and a compression safety threshold.

Q: How do I install MCP Server?

A: You can use it as a single-file script (download and run with Node.js) or install it globally via npm (npm install -g tinypng-script-with-cache).

Q: Do I need a TinyPNG API key to use MCP Server?

A: Yes, MCP Server relies on the TinyPNG API, so you’ll need to obtain an API key from the TinyPNG website.

Q: Can I use multiple API keys with MCP Server?

A: Yes, MCP Server supports multiple API keys and will automatically switch to the next available key when one reaches its usage limit.

Q: How does MCP Server prevent re-compressing the same images?

A: MCP Server uses MD5 hashes to track which images have been compressed. It skips files with matching MD5 hashes on subsequent runs.

Q: Can MCP Server detect changes to images and re-compress them?

A: Yes, MCP Server uses MD5 hashes to detect changes. If an image has been modified, it will be re-compressed.

Q: Does MCP Server replace the original image files with the compressed versions?

A: Yes, MCP Server automatically replaces the original image files with the compressed versions after successful compression.

Q: What is the ‘compression safety threshold’ in MCP Server?

A: The compression safety threshold allows you to set a minimum compression ratio. If the compression ratio falls below this threshold, the original image will be preserved to avoid excessive compression and potential quality degradation.

Q: How do I pass parameters to MCP Server?

A: You can pass parameters via command-line arguments, such as the compression path and API key list. Parameters given through command line have a higher priority.

Q: Where can I find the source code for MCP Server?

A: The source code is available on Github.

Q: How does MCP Server integrate with UBOS?

A: Integrating MCP Server into UBOS streamlines the development workflow by automating image compression, improving application performance and user experience, and optimizing costs.
