- Nothing: it answered without a login
- Tools
- 13 tools
- Its own safety labels
- 13 read-only
- Memory it takes
- About 5,100 tokens of your AI's memory, just for its tool descriptions
- Largest answer
- About 21 KB in our test
- Speed
- Average answer in our test: 250 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, 9 Nov 2026.
Is Wieldr game radar MCP server safe?
- None of the hidden-instruction wordings we know were found in its 13 tool descriptions.
- Its error messages showed no secrets or internal details.
- All 13 of its tools are labeled read-only.
- Overall it scored 91/100 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.

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.
