Q: Is doc MCP server safe?

QAmcp's test on 5 Nov 2026: None of the hidden-instruction wordings we know were found in its 6 tool descriptions. Its error messages showed no secrets or internal details. 4 of its 6 tools are labeled read-only; the others may change or send things. Overall it scored 95/100 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.

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: 4 read-only, 1 labeled as deleting or destroying, 1 labeled as changing things
Memory it takes: About 2,600 tokens of your AI's memory, just for its tool descriptions
Largest answer: About 4.2 KB in our test
Speed: Average answer in our test: 289 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.

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.

scan_document

Recognise a passport, national ID card or driver's licence from a photo or scan and return what is printed on it as structured JSON.

Ready for the newest MCP version
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.

- !The tool list is about 58 KB (roughly 14k tokens). AI apps send it with every message, so it takes that much of the AI's memory before any work starts.
