Memory it takes

About 860 tokens of your AI's memory, just for its tool descriptions

Is legal-mcp server safe?

• None of the hidden-instruction wordings we know were found in its 3 tool descriptions.
• 0 of its 3 tools are labeled read-only; the others may change or send things.
• Overall it scored 83/100 on 9 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.

What it can do

3 tools, in the server's own words.
