At a glance
- Runs where
- On their server. What you send to it goes to them.
- What you need
- Nothing: it answered without a login
- Tools
- 6 tools
- Its own safety labels
- 6 read-only
- Memory it takes
- About 520 tokens of your AI's memory, just for its tool descriptions
- Largest answer
- About 1.3 KB in our test
- Speed
- Average answer in our test: 127 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 카볼트랩 CarVoltLab MCP server safe?
- None of the hidden-instruction wordings we know were found in its 6 tool descriptions.
- Its error messages showed no secrets or internal details.
- All 6 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.
What it can do
6 tools, in the server's own words.

Test results
Safe mode: only tools labeled read-only were run. How the test works
- !Ready for the newest MCP versionnote
1 warning
- !Uses an older MCP version (2025-11-25). It works today, but it isn't on the July 2026 version (2026-07-28) yet.
- !Bad inputs give a clean errornote
3 warnings
- !search: Accepted missing required input "query" without complaining
- !search: Accepted wrong type for "query" without complaining
- !carvoltlab_faq: Accepted wrong type for "query" without complaining
- and 2 more
- !Follows MCP best practices (not scored yet)note
2 tips (not scored)
- !Very common tool names: search, fetch. Next to other servers' tools the AI may mix them up; a short prefix helps (like "github_search" instead of "search").
- !1 tool answers with structured data but doesn't declare its shape (outputSchema): search. If those answers change shape, nothing can catch it; with a schema, every answer is checked.
