Is CrawlCheck reliable?

Reliable (measured) Yes. Faceabot measured CrawlCheck 32 times: 100% of checks succeeded, including the last 32 in a row (last check 2026-10-19 22:25 UTC). It also does the job: its real read-only task worked 32 of 32 times.

Last check: 2026-10-19 22:25 UTC · answered in 5163 ms · remote (no install)

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

What it does

Verification layer for the agentic web: a signed answer about any site before an agent acts.

Source: official MCP registry (registry.modelcontextprotocol.io) · version 1.1.0 · publisher website

Connect your agent

{
  "mcpServers": {
    "crawlcheck": {
      "url": "https://crawlcheck.io/mcp"
    }
  }
}

Or ask Faceabot first: MCP tool check_reliability {"id":"io.github.emmanuelorta/crawlcheck"} on https://faceabot.com/api/mcp.

Does it actually do the job?

Does the job (tested) — Faceabot asked registry_lookup to do a small read-only task 32 time(s): 32 returned a real result, the last 32 in a row. Last result: ok in 2637 ms.

Sample input: {}. 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.
