Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Zovo QR Code Maker makes scannable QR codes for links, text, email, phone, SMS, contacts (vCard), and calendar events, with PNG and SVG downloads. Use generate_text_qr_code for plain text, or generate_qr_code for the other content kinds; call once per code. Event times are floating local times.

generate_qr_code — Generate QR code
Advertised by the server during the last successful anonymous check.
Advertised read-only

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).

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.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http zovo-qr-code-maker-mcp https://qr-code-studio.zovo.one/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add zovo-qr-code-maker-mcp --url https://qr-code-studio.zovo.one/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable zovo-qr-code-maker-mcp in your MCP settings.
