SKILL 36 — SOLIDITY AUDIT MCP: CLAUDE-NATIVE SMART CONTRACT SCANNER

From: github.com/mariano-aguero/solidity-audit-mcp — MCP server plugging Slither + Aderyn + SWC patterns into Claude Code 10 tools. 19 built-in finding explainers. 86 SWC detectors. DeFi + Web3 preset detector packs. CI/CD ready.

WHAT IT IS

An MCP server that gives Claude Code direct access to Slither, Aderyn, Slang AST, SWC pattern matching, and a gas optimizer — all in one unified pipeline with auto-deduplication. Instead of context-switching between tools, you ask Claude to audit a contract and get a merged, severity-sorted report.

Stack:

External (install separately):
  Slither   → Trail of Bits, 90+ detectors, deep data flow
  Aderyn    → Cyfrin Rust-based, fast AST analysis
  Echidna   → Property fuzzer (optional)
  Halmos    → Symbolic execution (optional)

Built-in (no install):
  Slang     → Nomic Foundation AST parser, precise pattern matching
  SWC       → 86 detectors against Smart Contract Weakness Classification registry
  Gas       → Storage packing, loop, calldata optimizations

INSTALL & CONFIGURE

# Prerequisites
pip install slither-analyzer solc-select
solc-select install 0.8.20 && solc-select use 0.8.20
curl -L https://foundry.paradigm.xyz | bash && foundryup

# Aderyn (Rust)
cargo install aderyn
# or: curl -L https://raw.githubusercontent.com/Cyfrin/aderyn/dev/cyfrinup/install | bash

# MCP server
npm install -g solidity-audit-mcp
# or: npx solidity-audit-mcp

# Optional fuzzers
brew install echidna    # macOS
pip install halmos      # symbolic execution

Wire into Claude Code — add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "audit": {
      "command": "npx",
      "args": ["solidity-audit-mcp"]
    }
  }
}

Or project-level .mcp.json in repo root:

{
  "mcpServers": {
    "audit": {
      "command": "node",
      "args": ["/path/to/solidity-audit-mcp/dist/index.js"]
    }
  }
}

Docker (all tools pre-installed):

docker run -v $(pwd):/contracts solidity-audit-mcp audit /contracts/Token.sol

THE 10 MCP TOOLS

`analyze_contract` — Full Pipeline (Start Here)

analyze_contract(
  contractPath: "contracts/Vault.sol",
  analyzers: ["slither", "aderyn", "slang"],   # or omit for all
  runTests: true                                 # run forge tests too
)

Pipeline:

Parse metadata (functions, state vars, inheritance)
Run Slither + Aderyn in parallel
Detect risky patterns via Slang AST
Deduplicate findings across all tools
Sort by severity
Return unified report + JSON

`get_contract_info` — Attack Surface Map (No Analysis)

get_contract_info("contracts/Protocol.sol")

Returns instantly:

Functions by visibility (external, public, internal, private)
Payable functions — all ETH entry points
delegatecall usage — proxy risk surface
State variables and modifiers
Inheritance chain

Use before full audit to understand the attack surface.

`check_vulnerabilities` — SWC Pattern Scan

check_vulnerabilities(
  contractPath: "contracts/Token.sol",
  detectors: ["SWC-107", "SWC-115", "CUSTOM-017"]  # or omit for all 86
)

19 built-in finding explainers (full Foundry PoC + remediation):

ID	Finding	Severity
SWC-107	Reentrancy	Critical
SWC-112	Delegatecall to untrusted callee	Critical
CUSTOM-017	Missing access control on critical function	Critical
CUSTOM-018	ERC-7702 unprotected initializer	Critical
CUSTOM-004	Price oracle manipulation / flash loan	Critical
CUSTOM-032	ERC-4337 paymaster drain	Critical
SWC-101	Integer overflow/underflow (unchecked)	High
SWC-104	Unchecked call return value	High
SWC-115	Authorization through tx.origin	High
CUSTOM-001	Array length mismatch	High
CUSTOM-011	Signature without replay protection	High
CUSTOM-029	Merkle double-claim	High
SWC-116	Block timestamp dependence	Medium
CUSTOM-005	Missing zero address validation	Medium
CUSTOM-013	Hash collision via abi.encodePacked	Medium
CUSTOM-015	Division before multiplication	Medium
CUSTOM-016	Permit without deadline	Medium
SWC-100	Function default visibility	Medium
SWC-103	Floating pragma	Low

`explain_finding` — Deep Dive on Any Finding

explain_finding(
  findingId: "CUSTOM-011",         # or "SWC-107", or keyword "reentrancy"
  contractContext: "ERC4626 vault with harvest callback"
)

Returns: root cause → impact → step-by-step exploit → vulnerable code → secure code → Foundry PoC template → remediation → references.

Use this mid-hunt when you find a suspicious pattern and want the full exploit scenario before writing a PoC.

Supported keywords: reentrancy, overflow, flash loan, oracle, replay, nonce, encodepacked, precision loss, permit, access control, merkle, airdrop, erc-7702, paymaster, erc-4337, delegatecall, tx.origin, zero address, timestamp

`generate_invariants` — Auto-Generate Foundry Invariant Tests

generate_invariants(
  contractPath: "contracts/Vault.sol",
  protocolType: "vault"    # auto, erc20, erc721, vault, lending, amm, governance, staking
)

Returns ready-to-paste invariant_*() functions + handler contract + forge test --invariant run commands.

Protocol-specific invariants generated:

ERC-4626 vault:    totalAssets >= total share value
                   share price non-decreasing
                   deposit/withdraw round-trip solvency
Lending:           protocol solvency, liquidatable positions
AMM:               constant product k, no free lunch on swap
Staking:           reward monotonicity, total staked balance, slash accounting
Governance:        proposal state machine, quorum immutability

`diff_audit` — Audit Only Changes

diff_audit(
  oldContractPath: "v1/Vault.sol",
  newContractPath: "v2/Vault.sol",
  focusOnly: true   # only report issues in changed code
)

Returns: functions added/removed/modified, new vulns introduced, issues resolved. Use on upgrade PRs.

`audit_project` — Whole Directory

audit_project(
  projectRoot: "./contracts",
  exclude: ["node_modules/**", "test/**", "mocks/**"]
)

Aggregated findings across all .sol files + per-contract breakdown + project-level risk score.

`optimize_gas` — Gas Analysis

optimize_gas("contracts/Protocol.sol", includeInformational: true)

Returns: storage packing opportunities, loop optimizations, calldata vs memory, visibility suggestions, estimated savings per change.

`run_tests` — Forge Integration

run_tests(projectRoot: ".", contractName: "Vault")

Returns: pass/fail/skip counts, coverage %, gas report, execution time.

`generate_report` — Formatted Output

generate_report(findings, contractInfo, format: "markdown", projectName: "Protocol")

Formats into: executive summary + risk level + findings table + remediation guidance.

DeFi DETECTOR PRESET

The defi.json preset contains 10 high/medium severity DeFi-specific detectors:

oracle-manipulation      → HIGH  — spot price used, no TWAP, no staleness check
flash-loan-risk          → HIGH  — balance check before/after single tx
slippage-check           → HIGH  — swap with no minOut parameter
reentrancy-erc777        → HIGH  — ERC777 tokensReceived callback reentrancy
donation-attack          → HIGH  — totalAssets() uses balanceOf (inflatable)
price-stale-check        → HIGH  — Chainlink latestRoundData without check
unchecked-transfer       → MEDIUM — transfer/transferFrom return value ignored
precision-loss           → MEDIUM — division before multiplication
front-running-vulnerable → MEDIUM — state change in predictable order
liquidity-removal-risk   → MEDIUM — LP withdrawal without reserve check

Dependency or permission surface needs review
Permission surface may require sandboxing
Financial research output is not financial advice; require human review before any live investment decision
Potential broker, wallet, exchange, or real-money execution surface; sandbox and explicit approval are required
No explicit security warnings about running analysis on untrusted or malicious contracts, which could potentially exploit the tooling.
The skill relies on external tools (Slither, Aderyn, etc.) that must be installed separately; failure to install them may break the workflow, but installation steps are provided.
Financial research output is not financial advice; require human review before any live investment decision.
This skill may touch real-money trading, broker, wallet, or exchange operations; use only in a sandbox with explicit approval.
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution
Stars/forks activity: 156 stars, 39 forks; issue activity unavailable in current metadata
Dependency/runtime risk: command execution surface, credential or environment access
