Bridge Security MCP Server 🌉⚡

$2.8B stolen from bridges. Every L2 needs an auditor. Now it's an MCP server.

Cross-chain bridge security auditing toolkit exposed as a Model Context Protocol (MCP) server. Connect any MCP client (Claude, Cursor, OpenClaw, etc.) and audit bridge contracts via natural language.

What It Does

Tool	What It Finds
bridge_analyze	Centralization risks, replay attacks, reentrancy, signature malleability, missing verification
bridge_fuzz	Message replay, ordering faults, timeout exploits, relayer failure, race conditions
bridge_simulate_validators	Byzantine faults, collusion, key compromise, offline validators, optimal thresholds
bridge_track_supply	Double mints, orphaned locks/mints, supply drift, missing burns
bridge_generate_report	Structured audit reports (standard, Immunefi, Code4rena templates)

pip install mcp-server-bridge-security
# OR

Usage Examples

Once connected, ask your AI agent:

"Analyze this bridge contract for vulnerabilities: contracts/ETNBridge.sol"

"Simulate a 5-validator bridge with 3-signature threshold and 1 Byzantine validator"

"Fuzz this bridge for replay attacks and race conditions"

"Track supply across chains for these bridge events and detect double mints"

"Generate an Immunefi-style report from these findings"
