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

Production Metrics

  • ✅ 18+ Production-Ready Tools

  • ✅ 1,547 lines of TypeScript

  • ✅ Comprehensive Testing Suite

  • ✅ Professional Documentation

  • ✅ Multiple Demo Interfaces

Quick Start

Prerequisites

  • Node.js 18+

  • pnpm or npm

  • Arbitrum RPC access

Installation

# Clone the repository git clone https://github.com/WuodOdhis/arbitrum-bridge-mcp-server.git cd arbitrum-bridge-mcp-server # Install dependencies npm install # Set up environment cp .env.example .env # Edit .env with your RPC URLs # Build the project npm run build # Run the comprehensive demo node showcase.js

MCP Inspector Integration

# Start MCP server with Inspector npm run inspect:npx

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

npm run inspect:npx

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" });

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Enables AI agents to perform cross-chain bridging operations using natural language intents, with support for multiple protocols (Across, Stargate) and advanced security features like oracle validation and slippage protection. Provides comprehensive bridging tools including quote estimation, transaction building, and approval management across Arbitrum and Ethereum networks.
