| 🔥 Working Exploit PoCs | Generates executable Foundry/Hardhat proof-of-concept for every finding |
| 🔬 Mainnet-Fork Simulation | Tests vulnerabilities against live chain state via Anvil/Tenderly |
| 📊 Gas Profiling | Identifies optimization opportunities with precise gas cost breakdowns |
| 🏷️ On-Chain Certificates | Soulbound NFT audit certificates on Berachain for verified audits |
| 📋 Multi-Format Reports | Markdown, HTML, PDF, and shareable PNG audit cards |
📋 Prerequisites
Before installing AuditSentry, make sure you have the following tools:
| Tool | Version | Purpose |
|---|---|---|
| Node.js | >= 18 (LTS) | Run MCP servers and scripts (npm included) |
| Git | Any recent | Clone the repository |
make | Built-in | Run the build pipeline (make build) |
macOS users:
makeis pre-installed via Xcode Command Line Tools (xcode-select --install). Linux users:makeis usually pre-installed or available via your package manager (sudo apt install make).
Verify your installation:
node -v # should show v18.x or higher
npm -v # should show v9.x or higher
git --version
make --version
🚀 Quick Install
# Clone the repository
git clone https://github.com/iktok90-design/ai-smart-contract-auditor.git
cd ai-smart-contract-auditor
# Build MCP servers + tooling
make build
# Run a demo audit on the bundled vulnerable contract
make audit-demo
Claude Code Plugin (local install)
# Clone and build — MCP servers must be compiled to work with Claude Code:
git clone https://github.com/iktok90-design/ai-smart-contract-auditor.git ~/.claude/skills/auditsentry
cd ~/.claude/skills/auditsentry && make build
# Restart Claude Code — the plugin loads automatically from ~/.claude/skills/
Marketplace listing pending. Once approved, install via
/plugin install auditsentry.
Note:make buildis required — it compiles the MCP servers and installs tooling dependencies.

💬 What Researchers Say
"AuditSentry caught a read-only reentrancy in our lending protocol that two manual audits missed. The working PoC exploited it on first run against a mainnet fork. This tool has become essential in our audit stack." — Security Researcher, Web3 Audit Firm
"The 23-agent parallel architecture is a game changer. Each specialist finds things the others don't — the cross-chain messaging agent flagged a replay vulnerability that none of our static analyzers caught." — Lead Auditor, DeFi Security Team
