# QrVerloz MCP Server > Dynamic QR codes — create, retarget, and inspect from any AI assistant. > No account required to start. [](https://modelcontextprotocol.io) [](LICENSE) --- ## What is QrVerloz? QrVerloz is a dynamic QR code service. Unlike static QR codes, QrVerloz codes are **retargetable** — you print once and change the destination at any time without reprinting. Track every scan with real-time analytics, schedule automatic URL switches, and manage everything from your AI assistant via MCP. **MCP Server URL:** `https://qrverloz.com/api/mcp` No signup needed. Request an API key once and start creating codes immediately. --- ## Quick Start (30 seconds) ### 1 — Add the server to your AI client See [`mcp-config-examples/`](mcp-config-examples/) for ready-to-paste configs: | Client | Config file | |--------|-------------| | Claude Desktop (macOS / Linux) | [claude-desktop.json](mcp-config-examples/claude-desktop.json) | | Claude Desktop (Windows) | [claude-desktop-windows.json](mcp-config-examples/claude-desktop-windows.json) | | Claude Code | [claude-code.json](mcp-config-examples/claude-code.json) | | Cursor | [cursor.json](mcp-config-examples/cursor.json) | | VS Code with GitHub Copilot | [vscode-copilot.json](mcp-config-examples/vscode-copilot.json) | | Continue | [continue.json](mcp-config-examples/continue.json) | | Any other HTTP MCP client | [generic.md](mcp-config-examples/generic.md) | > **Claude Desktop on Windows:** use `claude-desktop-windows.json`. The standard `npx` command fails on Windows when Node.js is installed in `C:\Program Files` due to a path-with-spaces issue. The Windows config uses `cmd /c` to work around this. > **VS Code:** requires VS Code 1.96 or later with the GitHub Copilot extension. Place the config at `.vscode/mcp.json` in your workspace root. ### 2 — Get a free API token No email or password required. In your AI assistant, say: ``` Use the QrVerloz MCP tool to request an API key ``` The token is shown **only once** — save it immediately. > **Note:** There is a limit of one token request per IP per 24 hours to prevent abuse. If the call fails, wait 24 hours or sign up at [qrverloz.com](https://qrverloz.com) for a permanent account. > **⚠️ QR code lifetime:** Guest QR codes are permanently deleted ~180 days after the token is issued (90-day token + 90-day grace period). Claim your account at [qrverloz.com/claim](https://qrverloz.com/claim) before the token expires to keep your codes permanently. ### 3 — Add the token to your client config Replace `YOUR_API_KEY` in the config file with your token, then restart your AI client: ``` Authorization: Bearer qrv_... ``` ### 4 — Create your first QR code ``` Use the QrVerloz MCP tool to create a QR code with the title "My first QR" pointing to https://example.com ``` Your QR code is live at `https://qrverloz.com/r/{shortCode}`. Print it — you can change the destination any time. --- ## Tools Reference | Tool | Auth | Description | |------|------|-------------| | `request_api_key` | None | Get a free 90-day API token. No signup. | | `create_qr_code` | Optional* | Create a dynamic QR code pointing to a URL. | | `get_qr_code` | Required | Look up a QR code by ID or short code. | | `list_qr_codes` | Required | List all your QR codes with short URLs and destinations. | | `get_qr_scans` | Required | Get the total lifetime scan count for a QR code. | | `update_qr_target` | Required | Change where a QR code redirects — no reprinting needed. | | `delete_qr_code` | Required | Permanently delete a QR code and its scan history. | | `get_account_info` | Required | Check your plan, usage, and remaining QR code capacity. | *Anonymous `create_qr_code` returns an ephemeral CDN image URL (not stored, not retargetable).

Free accounts get up to 5 QR codes. > **⚠️ Important lifetime warning:** The token expires after 90 days. QR codes are **permanently deleted** approximately 90 days after token expiry (~180 days total from creation).

To claim a permanent account: [qrverloz.com/claim](https://qrverloz.com/claim) --- ## REST API A full REST API is also available for direct HTTP integrations. - Interactive docs: [qrverloz.com/docs/api](https://qrverloz.com/docs/api) ↗ - OpenAPI spec: [`openapi.yaml`](openapi.yaml) --- ## Examples Ready-to-run scripts are in: - [`examples/js/`](examples/js/) — Node.js 18+ (no dependencies, uses native `fetch`) - [`examples/python/`](examples/python/) — Python 3.8+ (requires `requests`) --- ## Troubleshooting ### The AI assistant doesn't recognise the tool name Do not type tool names as function calls (e.g. `request_api_key()`). Use natural language instead: > "Use the QrVerloz MCP tool to request an API key" ### Claude Desktop: `'C:\Program' is not recognized` (Windows) This is a Windows path-with-spaces error. Node.js installed in `C:\Program Files` causes `cmd.exe` to fail when the path is not quoted. **Fix:** use [`claude-desktop-windows.json`](mcp-config-examples/claude-desktop-windows.json) which uses `cmd /c` to avoid the issue. ### The MCP server is not connecting **Claude Desktop:** 1. Check the **hammer icon** (🔨) in the chat input bar — it lists connected servers. If QrVerloz is missing, the server failed to connect. 2. Open logs via `Help → Open Logs Folder` and look for errors from the `qrveloz` server. 3. Make sure Node.js 18+ is installed (`node --version`) and `npx` is available (`npx --version`). 4. Test the connection manually: `npx -y mcp-remote https://qrverloz.com/api/mcp` **VS Code with GitHub Copilot:** 1. Open the Command Palette (`Ctrl+Shift+P`) and run `MCP: List Servers` — QrVerloz should appear with status `running`. 2. If it shows an error, check that VS Code is 1.96+ and the Copilot extension is active. 3. Make sure `.vscode/mcp.json` is saved and the workspace is open. **Cursor / Continue / other HTTP clients:** 1. Verify the URL is exactly `https://qrverloz.com/api/mcp` — no trailing slash. 2. Confirm the `Authorization` header value starts with `Bearer ` (note the space). 3. Test the endpoint directly: `curl -X POST https://qrverloz.com/api/mcp -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}'` ### Token was shown but I did not save it Guest tokens cannot be recovered once the response is dismissed. Options: - Wait 24 hours and call `request_api_key` again from the same IP - Sign up at [qrverloz.com](https://qrverloz.com) for a permanent account with token management in the Settings dashboard ### Rate limit hit on `request_api_key` One guest token is issued per IP per 24 hours to prevent abuse. If you hit the limit, wait 24 hours or create a free account at [qrverloz.com](https://qrverloz.com). --- ## Pricing See [qrverloz.com/#pricing](https://qrverloz.com/#pricing) for current plan details and limits. --- ## License MIT — see [LICENSE](LICENSE).
