Tokens are an estimate: the characters in its tool names, descriptions and inputs, divided by 4. The exact number depends on your AI model. Safety labels are what the server says about itself. From our latest test, 5 Nov 2026.

Is shop MCP server safe?

• None of the hidden-instruction wordings we know were found in its 14 tool descriptions.
• Its error messages showed no secrets or internal details.
• 9 of its 14 tools are labeled read-only; the others may change or send things.
• Overall it scored 88/100 on 5 Nov 2026.

A test can only see what the server shows from outside, not what it does with your data behind the scenes. Connect servers from makers you trust.

What this test does not check

• Its source code and packages.
• What a tool quietly does behind the scenes, such as writing a file or calling another service.
• Instructions hidden inside live tool answers. We only look for those in tool descriptions.
• Hidden instructions worded in a way our list doesn't know yet.
• Tools that could change something. Those are read, never run.

Known security advisories

It lists no public code, so there is nothing to look up in GitHub Security Advisories or OSV.dev. QAmcp tests how a server behaves. It does not scan source code.

What it can do

14 tools, in the server's own words.

  Ready for the newest MCP version

  1 warning

  • !Uses an older MCP version (2025-11-25). It works today, but it isn't on the July 2026 version (2026-07-28) yet.

  note
• !
  Follows MCP best practices (not scored yet)

  1 tip (not scored)

  • !Very common tool names: search, status. Next to other servers' tools the AI may mix them up; a short prefix helps (like "github_search" instead of "search").
