Is CheckBiz Merchant Check reliable?

Flaky Partly. Faceabot measured CheckBiz Merchant Check 6 times and only 83% of checks succeeded. Plan a fallback. It answers, but its real task has not worked yet (0/5 real results): see "Does it actually do the job?" below.

En français : Instable. Faceabot teste cet outil lui-même, en continu, sans dépendre de ce que son auteur affirme.

What it does

Let your shopping agent check the shop before it pays: a real, active, EU-registered company?

Connect your agent

{
  "mcpServers": {
    "merchant-check": {
      "url": "https://api.checkbiz.eu/mcp"
    }
  }
}

Or ask Faceabot first: MCP tool check_reliability {"id":"eu.checkbiz/merchant-check"} on https://faceabot.com/api/mcp.

Does it actually do the job?

Fails real tasks — Faceabot asked check_merchant to do a small read-only task 5 time(s): 0 returned a real result. Last result: tool_error (the tool answered with an error for the neutral sample input) in 5080 ms.

Sample input: {"domain":"example.com"}. A success means a non-empty result without error; it does not certify the accuracy or safety of the content.

Method: MCP initialize then tools/list from Faceabot (FaceabotProbe/1.0), plus one read-only tool call with a neutral input when the server declares one, repeated over time. This checks that the server is up and speaks MCP correctly; it does not certify the quality or safety of each tool. How measurement works.
