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.

  Follows MCP best practices (not scored yet)

  1 tip (not scored)

  • !The tool list is about 73 KB (roughly 18k tokens). AI apps send it with every message, so it takes that much of the AI's memory before any work starts.
