Is Petstore MCP Server safe to install?

A server's blast radius is the most powerful thing each of its tools can do. This grades the tools it declares, read-only, not whether it is secure.

• mediumTool input schema asks for a credential×5

Keyword matches in tool descriptions and schemas. These are shown for transparency and are not part of the grade.
