Connect Barcode Tools (decode, render, GTIN validate) and your agent gets 4 tools, among them decode_barcode, list_formats, render_barcode. It answers at https://mcp.casuyi.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.casuyi.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
