QRCode.Pub MCP MCP server

An official MCP server provided by QRCode.Pub that exposes tools for generating free QR code images (PNG/SVG) and accessing paid x402 micropayment endpoints for web page extraction, metadata retrieval, and file hosting. It allows AI agents to generate QR codes, convert web pages to Markdown, extract page metadata, and host files without requiring an API key or account, supporting both free and pay-per-call operations via Streamable HTTP.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http qrcode-pub-mcp https://qrcode.pub/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 qrcode-pub-mcp --url https://qrcode.pub/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable qrcode-pub-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "qrcode-pub-mcp": {
      "url": "https://qrcode.pub/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "qrcode-pub-mcp": {
      "type": "streamableHttp",
      "url": "https://qrcode.pub/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start qrcode-pub-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "qrcode-pub-mcp": {
      "type": "http",
      "url": "https://qrcode.pub/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http qrcode-pub-mcp https://qrcode.pub/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "qrcode-pub-mcp": {
      "url": "https://qrcode.pub/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "qrcode-pub-mcp": {
      "serverUrl": "https://qrcode.pub/mcp"
    }
  }
}
