Is the mcp.guitarpracticeroutine.com MCP server safe to use?
Independent trust grade F (45/100). Tool "get_chord_chart_by_name" description contains prompt-injection / hidden-instruction markup. wmcp.sh continuously watches mcp.guitarpracticeroutine.com for tool drift and rug-pulls. The grade is free and identical whether or not the operator pays.
✓ Watched since 2026-10-06 — 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.
Developers see this F before they connect to mcp.guitarpracticeroutine.com.
Clear it: a Deep Audit shows exactly what to fix, and Monitoring proves the fix to everyone who checks your grade. Drop your email and we'll send this server's full findings + the fix path. The grade itself stays free.
We re-grade mcp.guitarpracticeroutine.com 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.
