base64_encode_textLABSCO SUMMARY
The conversion nobody wants to paste into a website.
Base64 is a two-minute job with an awkward habit: the fastest route is usually a stranger's web page. This does it in place, for text and for image files, with the output written where you want it.
What it is
A small Python MCP server for Base64 conversion. Text goes in both directions, images encode from a path on disk and decode back out to a file with the MIME type you name, and Data URL format is supported.
What you get
- Text encoded to Base64, and decoded back to text
- An image file on disk encoded to Base64
- A Base64 string written back out as an image file, with the MIME type you choose
- Data URL format supported
- The same conversions also exposed as MCP resources, with prompt templates for each
Requirements
Python with uv. No account and no key — it converts the text and the paths you hand it, locally.
Setup effort
Add the configuration to your client
USE CASES
01
Decoding a Base64 blob somebody sent you
Turn it back into readable text without leaving the conversation.
02
Embedding an image in a config file or a data URL
Encode the file from its path, in Data URL form when that is what the target needs.
03
Turning an encoded payload back into a viewable file
Write it out as an image at the path and MIME type you specify.
04
Encoding a string for a header or config value
One call, rather than a web tool and a copy-paste round trip.
