CVE-2026-45019 (SSRF) affects Chainlist MCP server packages, not itself

Pros and cons

Pros

  • Free and fully open-source; no account or payment needed
  • One-click network setup for MetaMask and hardware wallets
  • Standard reference cited across Reddit threads and tutorials
  • Covers major L2s like Base and OP Mainnet plus long-tail chains

Cons

  • No vetting — listing a network doesn't mean it's safe
  • Rampant impersonator sites and same-name token create real confusion
  • No uptime guarantees on listed community RPC endpoints
  • Minimal scope — no API, dashboards, or analytics
