Your agent is about to install a stranger's MCP server or skill. Know who you're dealing with before your agent does. Check any npm package below — free, no signup. The MCP server also exposes the deep code scanner that produced these checks.
v0.1.0 4 MCP tools live
Registry facts plus a typosquat screen against widely-used packages. This is the metadata half of the scan — the deep code scan runs over MCP, below.
The deep scan is read-only: it never modifies the target. Verdicts come back as a 0–100 score, a letter grade, and detailed findings.

Remote scans run on the TrustScan host and are path-scoped to the host’s own code — they demonstrate the scanner, they cannot scan your package. For YOUR package the reachable check is the npm metadata scan above — free, or payable per call over x402 (POST /api/x402/trustscan/npm) without the rate limit.
Scan before you trust. Free forever.
Prices in USD. The only paid path on this domain is the agent rail (x402) — there is no human checkout. Free tiers never expire.
