Arbitrum Bridge MCP Server

🌉 Arbitrum Bridge MCP Server

The most advanced cross-chain bridge tooling for AI agents - featuring intent-based bridging, multi-protocol intelligence, and production-grade security.

🚀 Breakthrough Features

🧠 Intent-Based Bridging

Natural Language Interface: "Bridge 100 USDC to Ethereum with low fees"
Smart Protocol Selection: AI compares Across vs Stargate routes automatically
Execution Planning: Complete transaction workflows with optimal parameters

⚡ Multi-Protocol Intelligence

Across Protocol: Fast, secure bridging with UMA optimistic oracle
Stargate V2: Credit-based bridging across 6+ chains
Unified Interface: One API for multiple bridge protocols

🔒 Advanced Security

Oracle Validation: Chainlink price feeds verify destination amounts
Permit Integration: EIP-2612 & Permit2 for gasless approvals
Slippage Protection: Dynamic slippage calculation with deadline enforcement
MEV Protection: Built-in safeguards against front-running

🎯 Core Tools

Bridge Operations

list_routes - Discover available bridge routes
estimate_bridge_quote - Get bridge quotes with fees
build_bridge_tx - Create unsigned bridge transactions

Stargate V2 Integration

list_stargate_pools - Available liquidity pools
get_stargate_credit - Check available bridge credits
get_stargate_quote - Get Stargate-specific quotes
build_stargate_bridge_tx - Create Stargate transactions

Intent-Based Bridging

process_bridge_intent - Natural language → Optimized transactions

Security & Validation

get_oracle_price - Chainlink oracle prices
validate_dest_quote_against_oracle - Price validation
compute_min_destination_amount - Slippage protection
compute_deadline - Transaction deadline calculation

Approval Management

build_approval_tx - Standard ERC-20 approvals
build_eip2612_permit - Gasless permit signatures
build_permit2_permit - Uniswap Permit2 integration

🧪 Testing & Demo

CLI Showcase (Recommended)

node showcase.js

Best for reviewers - Comprehensive demonstration of all features.

Interactive Web Demo

./start-web-demo.sh

Opens http://localhost:3002 with click-to-test interface.

MCP Inspector

Professional MCP client for detailed tool inspection.

🏗 Architecture

Transport Layer

STDIO: Direct MCP client integration
HTTP SSE: Web-based MCP clients
Dual Mode: Both transports simultaneously

Security-First Design

Zod Validation: Strict input/output schemas
Oracle Integration: Real-time price validation
Permit Support: Gasless approval workflows
No Signing: Only unsigned transaction artifacts

Multi-Protocol Support

Across Protocol: Optimistic oracle bridging
Stargate V2: LayerZero-based credit system
Extensible: Easy to add new protocols

🌐 Supported Networks

Arbitrum One (Primary): Chain ID 42161
Ethereum Mainnet: Chain ID 1
Extensible: Framework supports additional chains

📈 Example Workflows

Intent-Based Bridge

// Natural language input
{
  "intent": "Bridge 100 USDC to Ethereum with low fees and high speed",
  "userAddress": "0x...",
  "priority": "speed"
}

// AI processes and returns optimized execution plan
{
  "recommendedProtocol": "across",
  "executionPlan": [...],
  "estimatedTime": "2-3 minutes",
  "totalFees": "$0.85"
}

Multi-Protocol Comparison

// Get quotes from both protocols
const acrossQuote = await getAcrossQuote({...});
const stargateQuote = await getStargateQuote({...});

// AI compares and recommends best option
const recommendation = await compareProtocols({
  across: acrossQuote,
  stargate: stargateQuote,
  priority: "cost" // or "speed"
});
