		}
	}
}

Development

Prerequisites

  • Node.js 18+
  • pnpm (recommended)
  • TypeScript 5.0+

Setup

# Clone repository
git clone <repository-url>
cd fibrous-mcp

# Install dependencies
pnpm install

# Start development server
pnpm dev

# Watch mode with auto-reload
pnpm dev:watch

Code Quality

# Type checking
pnpm typecheck

# Linting
pnpm lint
pnpm lint:fix

# Code formatting
pnpm format
pnpm format:check

Testing

Comprehensive test suite with 82.6% coverage across all modules:

# Run all tests
pnpm test

# Watch mode for development
pnpm test:watch

# Coverage report
pnpm test:coverage

# CI mode
pnpm test:ci

Test Results:

  • 167/167 tests passing
  • 10 test suites, ~3.1s execution
  • Native BigInt with router-sdk v0.6.0

Test Coverage by Module

  • API endpoints: 17 tests
  • Server configuration: 14 tests
  • Tool handlers: 14 tests
  • Utilities: 122 tests (BigInt operations, configuration, responses, swap logic, validation)

Coverage Details

  • Statements: 82.56%
  • Branches: 73.46%
  • Functions: 75.71%
  • Lines: 83.18%

Technical Details

Native BigInt Integration

  • Router SDK v0.6.0: Latest Fibrous SDK compatibility
  • 50KB smaller bundle: Removed BigNumber.js dependency
  • Faster calculations: Native JavaScript bigint operations
  • Modern standards: ES2022+ features
// Example: Native BigInt usage
const amount = BigInt("1000000000000000000"); // 1 ETH
const route = await router.getBestRoute(amount, tokenIn, tokenOut, "base");

Architecture

  • MCP Protocol: Model Context Protocol compliance
  • Type Safety: Full TypeScript implementation
  • Error Handling: Comprehensive error management
  • Security: Environment variable validation and masking

Production Deployment

Environment Setup

# Production build
pnpm build:clean

# Production start
NODE_ENV=production pnpm start:prod

Security Considerations

  • Store private keys securely (use secrets management)
  • Configure appropriate RPC endpoints
  • Set up monitoring and logging
  • Use HTTPS for all external connections

Performance

  • Native BigInt: 2-3x faster than BigNumber.js
  • Bundle Size: 50KB reduction vs v0.5.x
  • Memory Usage: Optimized for long-running processes
  • Rate Limiting: 200 req/min (configurable)
