BridgeGuard MCP

Cross-chain bridge security audit tools for AI coding agents. Bridges account for 40%+ of all DeFi theft ($3.2B+ total losses). This is the first MCP server dedicated to bridge security.

Quick Start

{
  "mcpServers": {
    "bridgeguard": {
      "command": "npx",
      "args": ["-y", "bridgeguard-mcp"]
    }
  }
}

Tools (4)

| Tool | Description | |------|-------------| | bridge_scan_contract | Scan bridge Solidity code for 18+ vulnerability patterns | | bridge_architecture_review | Assess bridge design (validator model, thresholds, governance) | | bridge_exploit_database | Search $3.2B+ in known bridge exploits | | bridge_security_checklist | Comprehensive 40+ item audit checklist |

What It Detects

| Category | Patterns | Real-World Example | |----------|----------|--------------------| | Validator Security | Key concentration, low thresholds, single admin | Ronin ($624M), Harmony ($100M) | | Message Verification | Replay attacks, missing nonces, signature malleability | Wormhole ($326M), Nomad ($190M) | | Oracle Security | Stale prices, manipulation vectors | CrossCurve ($3M) | | Liquidity | Unrestricted mint/burn, no rate limits | Multiple bridges | | Access Control | selfdestruct, unprotected upgrades | Multiple bridges | | Cross-Chain | Chain ID spoofing, insufficient finality | BNB Bridge ($586M) |
