Playground

The four tools in your browser with the CLI line and the tool call for every state

The playground runs the library in this page. Encode, decode, identify and list, with the same executors the MCP server runs.

Pick a tool, pick an encoding, type. The answer shows up a moment after you stop. Underneath it you get the CLI line and the JSON a model would send for the same call, both ready to copy.

The address bar follows the form. ?op=identify&text=MZXW6=== opens straight on that question. Share it, bookmark it, paste it into an issue.

Nothing leaves the tab

No server reads what you type. Paste the mystery string from the ARG you're stuck on. It stays with you.
