Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2498 tokens (~227/item across 11 items; 10 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management40
- Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 MCP server?
io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 is a hosted endpoint at https://mcp.zovo.one/mcp/barcode, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 is an MCP server listed in the public MCP registry as io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13. QR codes and barcodes offline: WiFi, vCards, SEPA payment codes, Code 128, EAN-13, SVG or PNG. This page covers its hosted endpoint (https://mcp.zovo.one/mcp/barcode).
Is the io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 MCP server safe to use?
io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 scores 83 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 MCP server expose?
io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 exposes 10 tools: license_status, license_activate, qr_create, qr_wifi, qr_vcard, and 5 more. Their descriptions and schemas cost roughly 2,448 tokens of context every time the server is loaded.
Does the io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 MCP server require authentication?
Yes. io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 MCP server still maintained?
io.github.theluckystrike/barcode-qr-code-sepa-payment-ean13 is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
