Qualität und Sicherheit
Basierend auf einer automatisierten Analyse der Tool-Definitionen und der Einhaltung des Protokolls.
Kontextkosten
Dies ist die ungefähre Anzahl der Tokens, die jedes Mal verbraucht werden, wenn die Tools des Servers in den Kontext eines Modells geladen werden. Höhere Werte verringern die Aufmerksamkeit, die für andere Aufgaben verfügbar ist.

🟢qr_code(text, format, size, margin, error_correction, ...)
Make a QR code for any text, URL, Solana Pay / wallet address or Wi-Fi login — as a PNG (base64 data URL) or SVG, with size, margin, colours and error correction. Rendered on our server. For Wi-Fi pass wifi_ssid + wifi_password; for Solana Pay pass a solana: URI as text. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).

}🟢text_stats(text, extract)
Count characters, words, sentences, lines and paragraphs, estimate LLM tokens, reading time and readability (Flesch), and pull out every URL, email, @handle, #tag, number and crypto address.
