Speed

Average answer in our test: 104 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, 7 Nov 2026.

Is Eventual Premium Lock MCP server safe?

• None of the hidden-instruction wordings we know were found in its 7 tool descriptions.
• Its error messages showed no secrets or internal details.
• 3 of its 7 tools are labeled read-only; the others may change or send things.
• Overall it scored 89/100 on 7 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

7 tools, in the server's own words.

  3 tips (not scored)

  • !4 tools not labeled read-only don't say whether running them twice is safe (idempotentHint): create_quote, send_checkout_email, purchase_quote, complete_purchase
  • !7 tools don't say whether they reach outside services like the web (openWorldHint): get_product_catalog, read_declarations_page, create_quote, get_quote, send_checkout_email, purchase_quote and 1 more
  • !read_declarations_page: Labeled read-only, but its "filename" input is a file path with no pattern, length limit or fixed choices. Make sure the server first resolves the real path (following links and encoded dots like %2e%2e), then refuses anything outside its f
