querying-the-bumper-advisor

querying-the-bumper-advisor is a skill for Claude Code from gnana997/bumper. It costs 79 tokens per session (626 once invoked), scanned A, original, Apache-2.0.

A way to query the bumper Advisor, a hosted security knowledge base covering software vulnerabilities, malicious packages, and infrastructure-configuration mistakes.

In plain words
What is it for?
Use it to look up CVEs, check whether a package is known to be malicious, and find rules for Terraform, Kubernetes, Dockerfiles, and CloudFormation.
Why use it?
It provides reference information for security decisions without sending source code; only package details and queries leave the machine.

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

querying-the-bumper-advisor 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 10d 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

Querying the bumper Advisor

The bumper Advisor is a hosted knowledge base of CVEs, malicious packages, and IaC misconfiguration rules. Reach for it instead of guessing about a vulnerability, a package's safety, or a security finding. Only package names, versions, and queries leave the machine — never your code. Needs the bumper CLI and/or the bumper-advisor MCP wired by bumper init (https://github.com/gnana997/bumper).

How to reach it

Preferred — the bumper-advisor MCP server. Use fully-qualified tool names:

  • bumper-advisor:lookup_cve — CVEs affecting a package at a version (ecosystem, package, version)
  • bumper-advisor:get_vuln — full detail for one advisory id (CVE/GHSA); set include_insight for an AI-enriched explanation
  • bumper-advisor:check_malware — is a package known-malicious? (ecosystem, package)
  • bumper-advisor:search_cve — search CVEs by keyword / ecosystem / severity
  • bumper-advisor:search_rules — find IaC rules by keyword / provider / severity
  • bumper-advisor:get_rule — full detail for one IaC rule (source, source_id)

Fallback — the CLI (no MCP):

  • bumper search <query> — search the bundled IaC ruleset
  • bumper explain <RULE_ID> — one IaC rule in detail
  • bumper deps --json <lock> — vuln/malware data for a lockfile

When to use which

  • "Is X safe to install?" → bumper-advisor:check_malware, then lookup_cve.
  • "What does CVE-2023-… mean / how do I fix it?" → bumper-advisor:get_vuln.
  • "What's wrong with this Terraform/K8s/Dockerfile?" → bumper-advisor:search_rules then get_rule (or bumper plan.json for a full plan scan).

Example

User: "is the event-stream npm package safe?" → bumper-advisor:check_malware ecosystem=npm package=event-stream → flagged malicious (historic backdoor). Advise against it; suggest a maintained alternative.

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.
