Core premise: Every major security and compliance tool on the market is still operating on stale threat models. NIST 800-53, ISO 27001, SOC 2, and PCI-DSS were written for network-centric, on-prem or early-cloud environments. They have no controls for AI pipeline integ

Questions
What is the @blamejs/exceptd-skills MCP server?
AI security skills grounded in mid-2026 threat reality, not stale framework documentation
What tools does @blamejs/exceptd-skills expose?
11 in total: 11 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is @blamejs/exceptd-skills safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (23/100) and found 15 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does @blamejs/exceptd-skills need?
It reads EXCEPTD_ALLOW_WEAK_KEY_ACL, GITHUB_TOKEN, KEYS_ROTATED and NVD_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How current is this page?
The grade is for one exact copy of the source (783e16adaf56), read on 2026-10-12. The repository is watched and re-audited when it changes.
