What is knowledge-mcp?

A plugin that provides semantic search over engineering standards from organizations such as IEEE, INCOSE, and ISO. Semantic search finds passages by meaning rather than requiring exact keywords.

Use it to search engineering standards and retrieve relevant guidance while writing or reviewing system specifications.

It helps ground specifications in established systems-engineering guidance instead of relying only on general knowledge. This can make requirements and design decisions easier to support with standards.

Security

Grade A, and why

knowledge-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
