Is the crawlcensus.com MCP server safe to use?

Independent trust grade B+ (87/100). No blocking issues found in the static + spec checks. wmcp.sh continuously watches crawlcensus.com for tool drift and rug-pulls. The grade is free and identical whether or not the operator pays.

✓ Watched since 2026-10-30 — behavioral baseline locked. We re-check this server's tool surface on a schedule; if it adds, removes, or silently rewrites a tool (rug-pull), we record it.

Corpus-level statistics: how many measured domains block each AI crawler, mean access score, llms.txt adoption.

Observed behavior

No proxied traffic observed for this host yet. Connect it at /connect and its grade gains a measured Reliability score + per-tool behavioral evidence — the half a static scan can't produce.

No blocking issues found in the static + spec checks.

How this grade is computed. An open, independent rubric — Spec conformance (20%), Security mapped to the OWASP MCP Top 10 (30%), Reliability (20%), Tool hygiene (15%), Transparency (15%) — run by connecting to the server and inspecting its real MCP surface. The grade is free and identical whether or not the operator pays. v1 uses static + spec signals from a single connection; continuous uptime, real latency, and annotation-truthing (declared readOnly vs observed behavior) layer on via the wmcp.sh proxy.
