Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Blitz Strike

Reconnaissance at speed. Analysis in depth. Validation before report.

Blitz Strike is a structured penetration-testing methodology — reconnaissance, source analysis, and validation — delivered as a universal MCP server. It enumerates the attack surface (BLITZ), traces source-to-sink reachability (EAGLE-EYE), and verifies each finding live before it is reported (STRIKE). One server, every agent: scope enforcement to submission-ready findings in a single run_engagement call, with the relevant exploit-tool manual attached to every result.

A scan hit is a hypothesis. A live test is the verdict.

Blitz Strike exists to eliminate the two most common failure modes in automated security assessment: false positives from surface-level pattern matching, and unverified findings reported without live confirmation.


What it does

Blitz Strike is a Model Context Protocol (MCP) server (TypeScript / Bun) that packages a 3-tier security-audit methodology as callable tools — and runs the whole engagement server-side, so a single run_engagement call works from Claude Code, Cursor, Hermes, OpenCode, Claude Desktop, Gemini, or any MCP client.

The three tiers

Blitz Strike maps a structured penetration-testing methodology — reconnaissance, source analysis, and validation — into three tool tiers executed server-side.

| Tier | Name | Phase | What it does | |---|---|---|---| | 1 | BLITZ | Reconnaissance & attack-surface mapping | Enumerates the exposed attack surface at scale: unauthenticated entry points, dangerous sinks, and authentication boundaries. | | 2 | EAGLE-EYE | Static analysis & data-flow tracing | Traces source-to-sink reachability and enriches findings against the escalation-chain graph. Confirms a sink is reachable, unauthenticated, and exploitable — not merely present. | | 3 | STRIKE | Validation & exploitation | Performs live verification (marker reflection + negative control), scope enforcement, and orchestration so a finding is confirmed before it is ever reported. |

Reconnaissance → analysis → validation. Nothing is reported until STRIKE confirms it.

Beyond the three tiers, Blitz Strike also ships Web3 audit (deterministic Solidity + executable Foundry proof), a live logic-bug prober (sibling enumeration + differential IDOR), hunting intel (CWE/CVE watchlist + DNS sinkhole detection), and out-of-band proof — so IDOR/auth logic bugs, blind injection, and smart-contract findings are all caught and proven, not just pattern-matched.


Autonomous, LLM-driven

Blitz Strike is driven by the LLM — Claude, Hermes, OpenCode, Codex, or any MCP client. The LLM is the brain (plans, routes, delegates, judges); Blitz Strike is the deterministic hands + knowledge + guardrails.

A full engagement is one call, or a granular agent-orchestrated cycle:

npx blitzstrike serve --mcp   # connect your agent, then ask it to
                              #   "audit ./src" (source) or "audit https://example.com" (live)

The LLM classifies the target automatically (URL → live pipeline, filesystem path → source pipeline), then drives recon → analyze → verify → review → report — guided by the bundled doctrine (instructions + skills + per-step next_steps) and fanned out across the platform's native sub-agents.

→ Autonomy & doctrine — how the LLM is steered.

Why TypeScript / Bun

  • Single static binary via bun build --compile — ship one executable per platform.
  • Zero-install distribution via bunx blitzstrike / npx blitzstrike.
  • MCP TypeScript SDK first-class (@modelcontextprotocol/sdk).
  • One toolchain for dev + test + build + compile.

Quickstart (30 seconds)

# Zero-install — works from any MCP client, no clone, no build
npx -y blitzstrike doctor        # verify the environment
npx -y blitzstrike install       # auto-register with every detected agent CLI

npx blitzstrike install detects every installed agent CLI (Claude Code, Cursor, OpenCode, Codex, Hermes, Gemini, Windsurf, Copilot, Cline) and writes the correct MCP config to each one in its native format. Restart your agent and call run_engagement.

From source:

git clone https://github.com/shinthink/blitzstrike.git
cd blitzstrike
bun install
bun run src/index.ts serve --mcp

Client Configuration (works in any MCP client)

{
  "mcpServers": {
    "blitzstrike": {
      "command": "blitzstrike",
      "args": ["serve", "--mcp"]
    }
  }
}
  • Claude Code / Desktop: claude_desktop_config.json or .mcp.json
  • Cursor: .cursor/mcp.json
  • OpenCode: .mcp.json
  • Hermes: mcp_servers: in config.yaml
  • Gemini / Copilot: native MCP config

Run blitzstrike install to print the exact snippet.


CLI

blitzstrike serve --mcp       # start MCP server over stdio (default)
blitzstrike doctor            # health check: runtime + 130-tool catalog + creds
blitzstrike install           # write MCP config to detected clients (Claude/Cursor/OpenCode)
blitzstrike install --dry-run # preview the config without writing
blitzstrike sync-data         # fetch heavy datasets (payloads + templates) on-demand
blitzstrike update            # check for a newer version + refresh the data cache
blitzstrike version           # print version

What doctor checks

| Check | Status you'll see | |---|---| | Runtime (bun/node) | OK / FAIL + fix | | Security tools catalog | 63/130 installed, 67 on-demand | | FOFA credentials | OK / WARN + fix | | Data layers (chains + tools-catalog) | present / missing |

Each issue carries a fix: line — no guessing.

What install does

blitzstrike install detects which MCP client config files already exist (Claude ~/.claude.json, Cursor ~/.cursor/mcp.json, project .mcp.json) and merges the Blitz Strike server entry in — it never overwrites your existing MCP servers. With no client detected, it prints the snippet for manual paste.

The intelligence layer (WAF signatures, tech/CVE/port correlations, fuzzer data, vuln ontology, exploit payloads, nuclei detection templates) is sourced from airecon (MIT), PayloadsAllTheThings (MIT), and nuclei-templates (MIT) — loaded at runtime and wired into the tool surface above. The attack-vector taxonomy (intelligence/attack_vectors.json) is first-party.

317 indexed tool manuals + 17 playbooks from kali-pentest (Apache-2.0) — 334 manual files, 100% of the 130-tool catalog documented. These are NOT decoration — they are wired into the flow:

  • tool_lookup(name) auto-attaches the tool's full manual.
  • run_engagement() attaches the relevant manual per matched chain's tools field.

MEMORY — long-term knowledge (self-growing)

| Tool | Purpose | |---|---| | remember(topic, content, type, tags, verified) | Save a reusable insight (deduped). verified=true only if marker reflected + negative control inert. | | memory_lookup(query) | Search memory by topic/tag/content, scored. | | memory_list() | List all memory entries, grouped by type. | | memory_forget(id) | Remove a memory entry (append-only tombstone). | | confidence_weights(...) | Get or set the confidence-scoring weight factors. | | finding_attach_evidence(finding, type, description, content) | Attach a redacted + hashed evidence record to a finding. |

Memory is append-only JSONL at ~/.blitzstrike/memory.jsonl (override with BLITZSTRIKE_HOME). run_engagement auto-captures matched escalation chains as pattern entries (deduped by chain id), so the knowledge base grows with every engagement — no duplicate spam, and only verified=true entries are authoritative.

Escalation Chains (chains.json)

58 data-driven escalation chains, each with ordered steps carrying:

  • tool_hint — which Blitz Strike tool to use
  • success_criteria — binary observable for the step
  • invariant_check — the assumption that MUST hold for exploitation
  • negative_control — how to refute the finding

Examples: ssrf_cloud_metadata, lfi_log_poison_rce, appkey_leak_deserialization_rce, hmac_empty_key_forgery, intval_form_id_bypass, extract_variable_injection_lfi, split_controller_upload_bypass, race_condition_double_spend, ssti_template_injection_rce, jwt_alg_confusion_forgery, cache_poisoning_xss, subdomain_takeover, and more.

Edit chains.json to add knowledge — never hardcode in source.

Build

bun install          # deps
bun run typecheck    # tsc --noEmit
bun run build        # ESM bundle → dist/index.js
bun run test         # regression + benchmark suite (453 checks)
bun run compile      # single static binary → dist/blitzstrike

Quality (measured, not claimed)

Blitz Strike carries a benchmark suite and a coverage matrix so quality is a number you can re-run, not a claim.

  • Benchmark (run_enterprise_benchmark) — a labelled corpus of vulnerable + safe fixtures across PHP, JavaScript, Python, and Java. Current result: detection rate 1.0, false-positive rate 0, precision 1.0.
  • Coverage matrix (coverage_matrix) — 5 languages × sink classes = 84% coverage (php, javascript, python, java, rust). Uncovered pairs are legitimately absent from the language (e.g. Java has no eval, Python/Java no PHP-style file inclusion, JS no deserialization sink).
  • Attack-vector taxonomy (list_attack_vectors / attack_vectors) — a master reference of 34 attack-vector categories (588 vectors) so a driving agent can map the entire attack surface, not just the obvious sinks.
  • Regression suite — bun run test runs 453 checks covering finding lifecycle, evidence integrity, CVSS math, taint tracing, dedup, report integrity, and benchmark invariants. CI runs it on every push.

Methodology Notes

  • Sink ≠ vuln. A dangerous function in the same file as an unauth handler does not mean the handler calls it. Use eagle_eye to confirm scope.
  • File write ≠ RCE (CF-003). A writable file must be loaded by the runtime to be execution.
  • Default server config only. Default Apache FilesMatch .+\.ph(ar|p|tml)$ has a $ anchor — .php.jpg does not execute.
  • Every finding is a HYPOTHESIS until strike_verify reflects your marker AND the chain's negative_control stays inert.
