Perplexity

Encode and Decode Without Leaving Chat

The `encode_binary` tool gives your agent a direct way to handle data encoding. No more copy-pasting into some random website or running a one-off script. Just tell Claude what you need converted. You ask, it answers. Give it a string and specify Base64, Hex, or Base64URL. Your AI client gets back the exact encoded text, ready for the next step of your task. It’s that simple.

Get API Payloads Right the First Time

Lots of APIs want their data in a specific encoded format. This tool ends the guesswork. You can build a request, then have your agent use `encode_binary` to format a piece of it correctly just before sending. This is perfect for working with file contents, JWT components, or any binary data that needs to be sent as a string. Your agent handles the conversion, so you don't ship corrupted payloads.

A Dedicated MCP Server for Data Formatting

This isn't just a command, it's a dedicated MCP Server for one specific job. That means it's fast, reliable, and does exactly what it says on the tin. It's a building block for more complex workflows. Because it's a proper tool, Claude knows exactly what it can do—encode or decode—and which formats it supports. This leads to more reliable results than just asking the base model to try and guess the conversion.
