cisa-kev-mcp: Cursor rule for Cursor

.cursorrules

cursorrules is a cursor rule for Cursor from CSOAI-ORG/cisa-kev-mcp. It costs 194 tokens per session, scanned A, original, MIT.

An automatic rule that directs questions about CISA's Known Exploited Vulnerabilities catalogue and related vulnerability terms to dedicated security tools. CISA is a US cybersecurity agency, and a CVE is a standardized identifier for a software vulnerability.

In plain words
What is it for?
Use it for CISA KEV searches, CVE lookups, BOD 22-01 remediation deadlines, EPSS prioritization, recent catalogue alerts, or comparing a CycloneDX software inventory with known exploited vulnerabilities.
Why use it?
It helps security questions use the intended vulnerability data and operations instead of relying on an unsuitable general response. The listed tools cover catalogue searches, deadlines, exploit likelihood, alerts, and software-inventory checks.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/.

This is CSOAI-ORG/cisa-kev-mcp's own configuration. It tells Cursor how to work on cisa-kev-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cisa-kev-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cursorrules 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 1mo 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.

Changes

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.
