## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-28.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 58/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 765 tokens (~255/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 60/100
  - Stability observed for 18 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `generate_qr_code` (~597 tokens)

Generate a QR code image. Use this whenever a user asks to create, make, or generate a QR code for a URL, website, WiFi network, contact card, email, or text. Returns a hosted image URL and a base64 data URL for inline display. Colour, size, dot and corner styling, frames and captions are free on every plan and with no key at all — offer them freely. When authenticated, the QR code is saved to the user's account and svg/pdf output becomes available.

Input parameters:

- `caption` (string): Short text rendered under the code, e.g. 'Scan for the menu'. Forces a frame to be drawn, because the text needs a band to sit on. Free on every plan.
- `captionFont` (string): Typeface for the caption. Defaults to 'inter' (bold sans). 'pacifico' and 'dancing-script' are scripts, 'permanent-marker' is handwritten, 'playfair-display' and 'roboto-slab' are serifs. Ignored wit…
- `content` (string, required): The data to encode. Examples: 'https://example.com' for url, 'WIFI:T:WPA;S:MyNetwork;P:secret;;' for wifi, plain text for text type.
- `cornerStyle` (string): Shape of the three large corner squares. Free on every plan.
- `darkColor` (string): Hex color for dark QR modules, e.g. '#1a1a1a'. Defaults to '#000000'.
- `dotStyle` (string): Shape of the QR modules. Free on every plan, keyless sessions included.
- `format` (string): Output format, returned as a data URL of that type. Defaults to 'png'. svg and pdf REQUIRE an API key: vector and PDF are the most expensive render path, so they sit behind a per-key rate limit rathe…
- `frameStyle` (string): Draw a frame around the code. 'square' means no frame. Free on every plan.
- `lightColor` (string): Hex color for the background, e.g. '#ffffff'. Defaults to '#FFFFFF'.
- `name` (string): Display name when saving via the authenticated API. If omitted, a name is derived from type and content.
- `size` (integer): Output image size in pixels (64–1024). Defaults to 256.
- `type` (string, required): QR code type. Use 'url' for web links, 'wifi' for network credentials (format: WIFI:T:WPA;S:<ssid>;P:<password>;;), 'contact' for vCard data, 'text' for arbitrary strings, 'email' for email addresses…

### `list_qr_codes` (~86 tokens)

List QR codes saved to the authenticated user's account. Supports pagination and filtering by type. Requires an authenticated API key (Developer plan).

Input parameters:

- `limit` (integer): Number of QR codes per page (1–100). Defaults to 20.
- `page` (integer): Page number for pagination. Defaults to 1.
- `type` (string): Filter by QR code type.

### `get_analytics` (~82 tokens)

Get scan analytics for the authenticated user's QR codes. Optionally filter to a specific QR code by ID. Requires an authenticated API key (Developer plan).

Input parameters:

- `qrCodeId` (string): Filter analytics to a specific QR code ID. Omit for account-wide totals.
- `timeRange` (string): Time range for analytics data. Defaults to '30d'.

TheQRCode.io is an MCP server listed in the public MCP registry as io.theqrcode/qr-code-generator. Free styled QR codes, no key: URL, WiFi, contact, text, email. API key adds saved codes + analytics. This page covers its hosted endpoint (https://mcp.theqrcode.io/mcp).

### Is the TheQRCode.io MCP server safe to use?

TheQRCode.io scores 70 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 TheQRCode.io MCP server expose?

TheQRCode.io exposes 3 tools: generate_qr_code, list_qr_codes, get_analytics. Their descriptions and schemas cost roughly 765 tokens of context every time the server is loaded.

### Does the TheQRCode.io MCP server require authentication?

No. We connected to TheQRCode.io without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the TheQRCode.io MCP server still maintained?

TheQRCode.io is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
