Clyro MCP Server

Work on your Shopify theme from the AI you already use. Your agent does the thinking on its own subscription, Clyro provides your theme files, Shopify validation, live previews, and verified exports. No Clyro credits spent, except image generation. Included with every Clyro account - the Free plan gets 300 MCP tool calls a week, paid plans are unlimited.

Connect Claude

1. In Claude, open Settings > Connectors > Add custom connector.
2. Name it Clyro, paste this URL, leave the advanced fields empty, and click Connect:

https://mcp.clyro.com

3. Sign in with your Clyro account and click Approve.

That's it. Works on claude.ai, Claude Desktop, and the mobile apps.

Connect ChatGPT

1. In ChatGPT, open Settings > Connectors and create a new connector (turn on Developer mode in advanced settings if you don't see the option).
2. Name it Clyro, paste https://mcp.clyro.com as the MCP server URL, pick OAuth, and save.
3. Sign in with your Clyro account and approve.

Connect coding agents (Claude Code, Cursor, Codex...)

Same story everywhere: one URL and a browser sign-in. Add https://mcp.clyro.com as a Streamable HTTP MCP server, trigger the sign-in, click Approve. In Claude Code that's:

claude mcp add --transport http clyro https://mcp.clyro.com

then /mcp inside a session. Cursor asks for the login itself, Codex does it with codex mcp login clyro, OpenCode prompts on first use.

Or don't even read that. Paste this to your agent and let it do the work:

Add the Clyro MCP server to this tool for me: https://mcp.clyro.com
(MCP over Streamable HTTP, OAuth sign-in, no keys or headers needed).
Configure it, trigger this tool's MCP sign-in so I can approve in my
browser, then prove it works by calling the list_themes tool and
telling me my themes.

Every connected agent shows up in Settings > Connected agents, where you can disconnect it anytime. And if some tool of yours can't do OAuth sign-in, there's an API key in the same place: send it as an x-api-key header instead.

Try it

Use Clyro to list my themes and show me a preview of the homepage.

Then just talk. Keep the Clyro editor open in another tab and watch changes land live:

• The announcement bar says 10% off. Make it 15% and use a red background.
• My hero looks cramped on mobile. Fix the spacing without touching desktop.
• Rebuild the homepage for a skincare brand called Lumen. Hero, bestsellers, reviews, FAQ.
• Run a full audit and fix everything you find.
• The theme is ready. Export the ZIP.

One clear request per message beats a paragraph of ten. Exports are verified on a real Shopify store before you get the link, so if Shopify would complain, your agent hears about it first and fixes it in the same conversation.

Good to know

tl;dr: when something gets weird, start a fresh chat. Long agent sessions are the number one cause of issues, and the connection itself is stateless.

• Can't connect? The URL is exactly https://mcp.clyro.com, and for Claude the advanced OAuth fields stay empty.
• "quota_exceeded" - the Free plan includes 300 MCP tool calls a week; the error tells you when the counter resets. Upgrade for unlimited access. Only real tool calls count - connecting, listing tools and other client overhead is free.
• Agent can't see your themes? Disconnect and reconnect in your client's settings. Check what's connected in Settings > Connected agents.
• Images cost credits. About 25 per image, on plans with image generation. Everything else is free of Clyro credits.
• Limits: Free plan 300 tool calls a week; previews 100 a day, images 40 a day, export links single-use and valid 5 minutes (just ask again). Theme count follows your plan.
• Exporting accepts Clyro's Terms of Service, same as the editor's Export button.

Tools

Your agent discovers these on its own, you never have to name them: list_themes, create_theme, read, search, edit, write, template, edit_json, diagnose, preview, generate_image, export_zip, shopify_docs. Ready-made prompts ship too, in your client's prompt picker: audit_theme, cro_pass, and fix_export.

Happy prompting.
