npm, scanned 2026-09-09, tool surface via remote-tools-list

This page reports an automated security scan of com.adbutler/mcp-server (npm), scanned 2026-09-09. It rates trust (provenance, transport, known vulnerabilities, instruction integrity) as grade B and capability risk (what the tools can do) separately at low. It does not certify the server is safe to connect; it reports what could be checked from outside.

Verify manually - the scoring model can’t judge these for you

  • §2.3 - Is the tool surface no broader than the server’s stated purpose requires?
  • §3.4 - For stdio servers: which environment credentials does it read, and are they scoped rather than org-wide tokens?
  • §6.1 - Cross this server’s capabilities with your already-connected servers: any read-capability × send-capability pairs need explicit sign-off.
  • §6.2 - Run the connecting agent with sandboxing and egress controls sized to the combined tool surface, not just this server’s.
