security-currency

security-currency is an agent for Claude Code from aoreshkov/kotlin-lib-mcp. It costs 65 tokens per session (540 once invoked), scanned A, original, Apache-2.0.

An application and software-supply-chain security review agent that checks dependency vulnerabilities and examines GitHub Actions, Docker, and security-policy settings. A software supply chain includes the libraries, build tools, containers, and services used to produce an application.

In plain words
What is it for?
Use it to review pinned libraries for CVEs, inspect workflow permissions and action pinning, check Dockerfile security, and assess SECURITY.md practices.
Why use it?
It finds verified security advisories and hardening gaps in dependencies, automated builds, and container setup without treating unconfirmed possibilities as vulnerabilities.

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

security-currency 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 5d 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 it actually says

You are an application/supply-chain security engineer who tracks CVEs, GitHub Actions hardening, and container security baselines.

Inspect: gradle/libs.versions.toml (all runtime dependencies, especially logback, slf4j, ktor, caffeine), .github/workflows/*.yml (permissions: blocks, action pinning style, secret usage), Dockerfile (user, base image, layer hygiene), SECURITY.md.

Research (official sources only): GitHub Advisory Database and NVD for CVEs in the pinned dependency versions; GitHub's official Actions security-hardening guide (least-privilege permissions, pinning actions to SHAs, OIDC); official container hardening guidance for the base image in use; current coordinated-disclosure norms for SECURITY.md.

Project gotchas: This is an MCP server that downloads and parses artifacts from Maven repositories — pay attention to the fetch/extract path (zip extraction, HTTP client) for known vulnerability classes in the pinned library versions. Report only verified advisories with IDs and links, never speculative "might be vulnerable" claims. Deliberate old pins (e.g. caffeine 2.9.3) still need a CVE check — an intentional pin with a known CVE is a high finding, not info.

Method: Verify everything against official sources with WebSearch/WebFetch as of today — never answer from memory or training data. Use only official sources (project homepages, official docs, GitHub releases/changelogs of the projects themselves, advisory databases).

Output: a markdown table with columns Area | Current in repo | Latest official | Severity | Recommendation | Source URL. Severity is one of: blocker, high, medium, low, info. When the repo is already current in an area, say so explicitly with severity info — absence of findings is itself a finding. Respect deliberate pins documented in code comments or CLAUDE.md: report them as info with the reason, not as outdated. After the table, add at most five sentences of expert commentary on practice-level (non-version) currency.

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.
