Is the npm:mcp-server-sfmc MCP server safe to use?

Independent trust grade B+ (89/100). Static analysis of npm package mcp-server-sfmc@2.9.0 (stdio server — no remote endpoint). Reliability/behavioral signals require running it; not measured. wmcp.sh continuously watches npm:mcp-server-sfmc for tool drift and rug-pulls. The grade is free and identical whether or not the operator pays.

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.
