aikido-mcp

Security analysis platform for Aiken smart contracts on Cardano.

Aikido goes beyond static analysis. It combines a 75-detector suite with SMT verification, transaction simulation, compliance analysis, protocol pattern detection, and grammar-aware fuzzing to find vulnerabilities in Aiken smart contracts before they reach mainnet. Multi-lane analysis cross-correlates evidence across techniques, producing findings with source context, severity ratings, CWE/CWC classifications, and actionable remediation guidance.

Built in Rust. Fast. Zero configuration required.

Why Aikido

Cardano smart contracts are immutable once deployed. A vulnerability in production means lost funds with no recourse. Manual audits are expensive, slow, and bottlenecked. Aikido catches the classes of bugs that auditors find most often - double satisfaction, missing signature checks, unbounded iteration, unsafe datum handling - automatically, in seconds.

• The only security tool for Aiken - no alternatives exist in the ecosystem
• 75 detectors with CWC (Cardano Weakness Classification) and CWE mappings
• Multi-lane analysis - static detectors, compliance, SMT verification, transaction simulation, protocol detection, fuzzing
• Validated against professional audit - 85% coverage on TxPipe's Strike Finance audit findings (full comparison)
• Evidence framework - findings corroborated across multiple analysis techniques (PatternMatch -> SmtProven -> SimulationConfirmed)
• 9 output formats - terminal, JSON, SARIF, Markdown, HTML, PDF, CSV, GitLab SAST, reviewdog
• Ecosystem proven - 10+ real-world projects including SundaeSwap, Anastasia Labs, Strike Finance, and Seedelf (0 crashes)

Quick Start

Install

# Homebrew (macOS/Linux)
brew install Bajuzjefe/tap/aikido

# Cargo (Rust >= 1.88.0)
cargo install --git https://github.com/Bajuzjefe/Aikido-Security-Analysis-Platform aikido-cli

# npm (wrapper)
npx aikido-aiken /path/to/project

# Docker
docker run --rm -v $(pwd):/project ghcr.io/bajuzjefe/aikido:0.3.1 /project

# From source
git clone https://github.com/Bajuzjefe/Aikido-Security-Analysis-Platform.git
cd aikido && cargo build --release

Run

aikido /path/to/your-aiken-project

Example Output

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  AIKIDO v0.3.1  Static Analysis Report
  Project: test/simple-treasury v0.1.0
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  [CRITICAL] (definite) double-satisfaction - Handler treasury.spend iterates
    outputs without own OutputReference - validators/treasury.ak:23

    Spend handler accesses tx.outputs but never uses __own_ref to identify
    its own input. An attacker can satisfy multiple script inputs with a
    single output, draining funds.

        22 | validator treasury {
    >   23 |   spend(
    >   24 |     datum: Option<TreasuryDatum>,
    >   25 |     redeemer: TreasuryRedeemer,

    Suggestion: Use the OutputReference parameter to correlate outputs
    to this specific input.

  ...

  1 critical, 5 high, 7 medium, 0 low, 0 info

Analysis Architecture

Aikido uses a multi-lane approach where independent analysis techniques cross-validate each other:

graph TB
    subgraph Input
        A[Aiken Project] --> B[Typed AST]
    end

    subgraph Analysis Lanes
        B --> C[Detector Suite<br/>75 detectors]
        B --> D[Compliance<br/>Securify2-style]
        B --> E[SMT Verification<br/>Cardano axioms]
        B --> F[Tx Simulation<br/>exploit generation]
        B --> G[Protocol Detection<br/>DeFi classification]
        B --> H[Fuzz Lane<br/>grammar-aware]
    end

    subgraph Evidence Correlation
        C --> I[Evidence Framework]
        D --> I
        E --> I
        F --> I
        G --> I
        H --> I
    end

    I --> J[PatternMatch]

Real-World Validation

Strike Finance Audit Comparison

Aikido was benchmarked against TxPipe's professional audit of Strike Finance (perpetuals + forwards contracts):

Full methodology and per-finding breakdown: AUDIT_COMPARISON.md

Ecosystem Validation

Validated against 10+ real-world Aiken smart contract projects with zero crashes:

Detectors

75 detectors mapped to CWE identifiers.

Each detector has detailed documentation with vulnerable examples, safe examples, and remediation guidance. Use aikido --explain <detector-name> or see docs/detectors/.

Output Formats

9 formats for different workflows:

aikido /path/to/project                        # Colored terminal output (default)
aikido /path/to/project --format json          # JSON (machine-readable)

Configuration

.aikido.toml

# Use a preset as a starting point

[detectors.severity_override]
unbounded-datum-size = "low"

# Per-file overrides
[[files]]
pattern = "tests/**"
