Best for
  • Authorized security researchers and red/blue team engineers who want verify-before-report workflows
  • Agent users who want a full penetration-testing flow driven by one call inside an MCP client
  • Developers and security reviewers needing code audit (taint analysis, source-to-sink, variant analysis)
  • Teams that want a structured methodology plus knowledge base (manuals, playbooks, escalation chains) instead of scattered scripts
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Anyone wanting to test external systems without explicit owner authorization
  • Anyone treating a scan hit as a confirmed vulnerability and skipping STRIKE validation
  • Users expecting everything to work offline out of the box — payloads and templates need `blitzstrike sync-data`, and fofa_search needs FOFA_EMAIL/FOFA_KEY
  • Users looking for an official or vendor-endorsed product; this is a community project
  • Projects outside the NPM ecosystem (e.g., pure Python/Go)
  • Environments without network access to deps.dev, OSV.dev, and the npm registry
  • Scenarios requiring maintenance by an official upstream vendor
Required permissions
  • Read the source directory or files being audited
  • Run a local process over stdio (command `blitzstrike`, args `serve --mcp`)
  • Make outbound HTTP requests to the audited target for live validation and recon
  • Write to client MCP config files (install merges into existing config, never overwrites)
  • Read/write memory and data cache under ~/.blitzstrike (overridable via BLITZSTRIKE_HOME / BLITZSTRIKE_DATA)
  • Optional: FOFA_EMAIL / FOFA_KEY for FOFA access, and H1_USERNAME to add the X-HackerOne-Research header
  • ensure_tool may auto-install missing security tools on the local machine
  • Network access to the NPM registry and external services (deps.dev, OSV.dev, OpenSSF, npms.io, GitHub)
  • Read access to workspace lockfiles (pnpm-lock.yaml, package-lock., yarn.lock) for cache invalidation
Risks and side effects
  • Live validation and live_recon send real requests to targets; misconfigured scope or missing authorization can cause harm or legal exposure
  • ensure_tool auto-installation modifies the local environment and introduces supply/version risk
  • Payloads, nuclei templates, and exploitation manuals are offensive material that can be misused
  • Memory is stored append-only as JSONL at ~/.blitzstrike/memory.jsonl and may accumulate sensitive target data
  • FOFA and HackerOne credentials are supplied via environment variables and can leak
  • Automated scan results can still be false positives — the README insists every finding stays a hypothesis until strike_verify confirms it
  • Third-party READMEs and changelogs are untrusted external content; they are wrapped in tags with _meta flags but should still be handled cautiously
  • Depends on availability and accuracy of external services
  • Batch requests are capped at 25 packages to prevent registry enumeration; larger sets require batching
  • Third-party open source project, not officially maintained by NPM or Anthropic
