Is CanWeShip Product Guidance MCP server safe?
- None of the hidden-instruction wordings we know were found in its 3 tool descriptions.

- Overall it scored 100/100 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
3 tools, in the server's own words.
list_productsread-onlyList the products CanWeShip checks, each with the first sentence of its answer, verification date and guide URL.
get_product_guidanceread-onlyGet preliminary U.S.
check_productread-onlyEvaluate supplied product facts through the same deterministic USPS, UPS and FedEx rule runtime used by the CanWeShip checker.
