Nothing: it answered without a login

Tools

21 tools

Its own safety labels

20 read-only, 1 labeled as changing things

Memory it takes

About 5,400 tokens of your AI's memory, just for its tool descriptions

Largest answer

About 17.2 KB in our test

Tools that look alike

1 pair of tools with nearly the same description, so the AI may pick the wrong one

Speed

Average answer in our test: 200 ms

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 Mamo MCP server safe?

• None of the hidden-instruction wordings we know were found in its 21 tool descriptions.
• Its error messages showed no secrets or internal details.
• 20 of its 21 tools are labeled read-only; the others may change or send things.
• Overall it scored 93/100 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

21 tools, in the server's own words.

Test results

Safe mode: only tools labeled read-only were run. How the test works

• !
  Every tool is described

  1 warning

  • !prepare_deposit and prepare_withdraw have nearly the same description (75% of their words are shared; the only difference: "deposit", "wrap", "exact" vs "withdraw", "plus", "unwrap"), so an AI may not know which to pick
