Frequently asked questions

1

How do I get a TinyPNG API key?

The README does not explain how to obtain an API key; you must have one to set in the `TINYPNG_API_KEY` environment variable.

2

What runtimes are required?

The server runs on Node.js or Bun. Both are supported via the `command` field in `mcp.json`.

3

Where are images sent for compression?

Images are sent to the TinyPNG API for compression. The server itself does not store images; the compressed file is saved to the path you specify.

4

What image formats are supported?

The server uses an enum called `SUPPORTED_IMAGE_TYPES`, but the exact list of formats is not provided in the README. Typical TinyPNG formats include PNG and JPEG.

5

Can I compress images without an API key?

No. A valid TinyPNG API key is required and must be provided in the environment configuration.
