MCP security grade A
[![MCP security](https://vulnrable.com/api/mcpbadge?pkg=%40modelcontextprotocol%2Fserver-sequential-thinking&eco=npm)](https://vulnrable.com/mcp/modelcontextprotocol--server-sequential-thinking/)

Automated registry-metadata scan; not a code audit. Findings come from npm metadata published by the package owner and from public security advisories (OSV/GHSA) — not from our own assessment of the code.
Grade scanned 2026-10-22 · package count resolved 2026-10-21. A package fixed after that date will still show its earlier grade here.
