Quality & Safety
A
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~1,834Tokens (tool definitions)
~9.0 KBTypical response size
Moderate attention impact (1.43% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢generate_qr_code(kind, url, text, email, subject, ...)
Use this when the user wants a QR code: for a website link, plain text, an email, a phone number, an SMS, a contact card (vCard), or a calendar event. Returns the code as SVG with PNG and SVG download links, plus scan warnings (low contrast, high density) and an optional minimum print size. Plain text and SMS text are limited to 1,500 characters; URLs to 2,000; encoded content must fit the QR byte capacity (1,273–2,953 bytes depending on error correction). Generates static codes only; it does not shorten links, track scans, or make Wi-Fi codes. Do not use for barcodes (EAN/UPC/Code 128).

}🟢generate_text_qr_code(text, foreground, background, error_correction, scan_distance_cm)
Use this when the user wants a PNG and SVG QR image that displays plain text when scanned. Accepts up to 1,500 characters, preserves whitespace, and reports contrast, density and optional print width. Encoded UTF-8 content must fit 1,273–2,953 bytes depending on error correction. Static codes only; does not read QR images or make barcodes or Wi-Fi codes.
