PopNx MCP’s three pillars

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

Common questions

Is Store Canary safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

README from the maker

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

Store Canary MCP connector

A free, hosted, read-only MCP server that checks a public WooCommerce store from the outside and answers in plain pass / warn / fail lines. No account, no API key, no install.

Connector address: https://mcp.storecanary.app/mcp (Streamable HTTP, no authentication)

Docs: https://storecanary.app/mcp

This repository only documents the hosted connector. It contains no server code.

Tools (all read-only)

ToolWhat it checks
check_storeOverall health: homepage reachable, HTTPS valid and redirects sane, WooCommerce detected, /cart/ and /checkout/ load, payment markers visible on checkout.
check_sslCertificate accepted, http:// permanently redirects to https://, short HTTPS-only redirect chain, HSTS header set.
check_exposureWordPress, WooCommerce, plugin and PHP versions shown publicly, a public /readme.html, a readable /wp-content/debug.log (log contents are never returned or kept).
check_seo_basicsrobots.txt (and whether it blocks the whole site), the XML sitemap, homepage title and meta description, homepage noindex.
check_speedTimes one download each of the homepage, one product page and the cart (one sample per page, not a lab test).
check_productsSamples up to 10 published products from the public WooCommerce Store API for missing prices, missing images and out-of-stock items.
check_policiesHomepage links to privacy, terms, shipping and returns/refunds pages, and each linked page loads.
explain_findingExplains any finding code (e.g. ssl_hsts, exposure_debug_log) in plain words, with a suggested fix. Makes no network requests.

Every tool takes a store url (except explain_finding, which takes a code). Checks use GET requests only: they never log in, add to cart or submit forms. Each runs once, when you ask; nothing is monitored or scheduled.

Starter prompts

  • black_friday_audit — *Audit my WooCommerce store before Black Friday.* Runs all seven checks and turns them into a prioritized pre-sale fix list.
  • checkout_check — *Is my checkout working?* Checks that the cart, checkout and payment methods load, and explains anything that doesn't.
  • explain_finding — *Explain this finding.* Explains a Store Canary finding id with a suggested fix.

Setup

ChatGPT

Until Store Canary is in ChatGPT's app directory, enable developer mode and add a custom connector with the URL https://mcp.storecanary.app/mcp/chatgpt and no authentication.

Claude

Open Settings → Connectors → Add custom connector and paste https://mcp.storecanary.app/mcp.

Cursor

Add to your mcp.json:

{

"mcpServers": { "store-canary": { "url": "https://mcp.storecanary.app/mcp" } } }

Cline and other MCP clients

Add a remote server over Streamable HTTP at https://mcp.storecanary.app/mcp. No auth headers are needed. For clients that only speak stdio:

{

"mcpServers": { "store-canary": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.storecanary.app/mcp"] } } }

Then ask: *"Check my store at example.com with Store Canary."*

Limits and safety

  • Up to 10 checks a minute per connection, plus a shared cap.
  • About five GET requests per check, no cookies, done in under 10 seconds. Requests identify as StoreCanaryBot.
  • Public web addresses only: no IP addresses, private networks or unusual ports.

Privacy

Store Canary does not store the store URLs you check, their results, or your IP address. See the privacy policy.
