Is the semiotic-mcp-server-481507046413.us-west1.run.app MCP server safe to use?

Independent trust grade A (93/100). No blocking issues found in the static + spec checks. wmcp.sh continuously watches semiotic-mcp-server-481507046413.us-west1.run.app for tool drift and rug-pulls. The grade is free and identical whether or not the operator pays.

✓ Watched since 2026-07-21 — 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.

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.

Findings

No blocking issues found in the static + spec checks.
Grade another server

We re-grade semiotic-mcp-server-481507046413.us-west1.run.app on a schedule and alert your Slack/webhook the moment its tools change or its grade drops — rug-pull insurance for the connection.

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.
