# 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:
```bash
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](docs/AUTONOMY.md) — 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)
```bash
# 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:
```bash
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)
```json
{
"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
```bash
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.

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.
### WEB3 — smart-contract audit + proof
| Tool | Purpose |

ERC721/ERC1155 callbacks, unchecked return/arithmetic, tx.origin auth, signature replay, selfdestruct, delegatecall, missing access control, timestamp dependence, spot-price oracle, unbounded loop, encodePacked collision, missing address(0) check) with CWE + severity + line refs. |
| `foundry_poc(class, contract)` | Generate an executable Foundry test that PROVES a Web3 finding. |
| `foundry_run(contract_code, poc_code, class_)` | Actually run the Foundry PoC (`forge test`) — a PASSING test = exploit reproduced (deterministic: forge's own verdict). |
### HUNTING — doctrine + live logic-bug prober + intel
| Tool | Purpose |
|---|---|
| `hunting_doctrine()` | High-ROI heuristics — sibling rule, A→B signal, two-account IDOR, PoC escalation, follow-the-money + the always-rejected kill-list. |
| `kill_list(type)` | Deterministic always-rejected check — missing headers, self-XSS, open-redirect-alone, SSRF-DNS-only, GraphQL-introspection-alone are N/A standalone. |
| `sibling_scan(base_url, endpoint, token_a, token_b)` | Deterministic LIVE logic-bug prober — sibling enumeration + differential IDOR + auth matrix + mass assignment + rate limit (closes the static-analysis gap on IDOR/auth logic bugs). |
| `auto_poc(type, base_url, endpoint, param)` | Turn a finding into a copy-paste-ready reproduction recipe (marker + negative control + expected differential + Patchstack-style title). |
| `watchlist()` | Ranked CWE frequency + high-value CVE watchlist with payout + saturated flag — "what to hunt next". |
| `resolve_check(host)` | Detect an ISP/country DNS sinkhole (blocking page) before auditing a sensitive-niche domain. |
| `oob_start()` / `oob_poll(id)` / `oob_stop(id)` | Out-of-band proof — interactsh listener for blind SSRF/XXE/SQLi/command-injection (the canary must actually arrive). |
### 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`,
