88/100 · MCP Trust Grade · checked 5h ago · MCP 2025-03-26

✓ Watched since 2026-06-03 — 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.

What it offers — 6 tools · Developer Tools

detect_runtime_capabilities

Report the hosted Apps SDK intake runtime capabilities and explain when the local stdio MCP is required.

inspect_url

Fetch a public or user-authorized URL and inspect title, metadata, frame policy, and likely source/embed candidates. Does not capture screenshots or p

discover_embed_candidates

Extract likely embed, preview, viewer, remix, and source URLs from a public or user-authorized page.

classify_clone_mode

Decide whether a reference should be embedded, sourced, locally captured, bounded-rebuilt, or blocked before reproduction.

generate_embed_snippet

Generate an iframe snippet for a known frameable and authorized URL. Does not verify frameability by itself.

plan_reproduction_path

Create a source-first plan that separates exact embed/source reuse from local capture and bounded rebuild work.

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 webembedding-mcp.vercel.app on a schedule and alert your Slack/webhook the moment its tools change or its grade drops — rug-pull insurance for the connection.

A live badge — it re-verifies itself and shows current stability. Static scorecards can't. Paste it in your README or site to show users you're independently audited.

Agents: check this before connecting

Add the wmcp.sh trust oracle as an MCP server and call grade_mcp_server / check_mcp_drift in your agent's pre-connection gate:

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.
