Shopify MCP server HTTP 500 error

[0xMarko]

Hello,

I'm using the Shopify Storefront MCP server to connect my AI agent to the Shopify stores.

It was working fine, but I suddenly started receiving HTTP 500 errors on multiple stores.

Is there something I might be missing?

Here is an example request that returns a 500 error:

HTTP POST: https://burton-snowboard.myshopify.com/api/mcp

Body: {
    "method": "tools/list",
    "jsonrpc": "2.0",
    "id": 1,
    "params": {}
}

Hi, thanks for the reply.

I already tried and implemented a lot of these things:
- exponential backoff

- tried using access token

- checked if other stores work (some work, some don't)

- request scope is minimal, I'm trying default example https://shopify.dev/docs/apps/build/storefront-mcp/servers/storefront#create-an-api-request-to-the-s...

I can't find any information related to rate limits, blocking, or throttling. Also, this was working on Friday, and now it does not work.

Any other ideas?

Same problem here. I guess there must have been an internal problem with the server. On Friday it was working

I don't see the issue anymore.

Can someone from Shopify please confirm if there was an issue on the Shopify side or if there is something regarding these specific stores?
