Prerequisites

  • Node.js >= 18.0.0
  • npm or yarn
  • Cosmos Network Access:
  • XRPL Access:
    • WebSocket endpoint (default: testnet)
    • Optional: Wallet seed for transactions

Installation

  1. Clone the repository:
git clone https://github.com/Quigles1337/COSMOS-MCP-SERVER-BRIDGE-EXPERIMENT.git
cd COSMOS-MCP-SERVER-BRIDGE-EXPERIMENT
  1. Install dependencies:
npm install
  1. Configure environment:
cp .env.example .env
# Edit .env with your configuration
  1. Build the project:
npm run build

Configuration

Create a .env file based on .env.example:

# Cosmos Configuration
COSMOS_RPC_ENDPOINT=https://rpc.cosmos.network:443
COSMOS_REST_ENDPOINT=https://api.cosmos.network
COSMOS_CHAIN_ID=cosmoshub-4
COSMOS_MNEMONIC=your_mnemonic_here
COSMOS_ADDRESS_PREFIX=cosmos

# XRPL Configuration
XRPL_SERVER=wss://s.altnet.rippletest.net:51233
XRPL_NETWORK=testnet
XRPL_SEED=your_seed_here
XRPL_ADDRESS=your_address_here

# Bridge Settings
BRIDGE_FEE_PERCENT=0.1
BRIDGE_MIN_AMOUNT=1
BRIDGE_MAX_AMOUNT=1000000
BRIDGE_TIMEOUT_SECONDS=3600

Usage

Running the Server

Development mode:

npm run dev

Production mode:

npm start

MCP Client Configuration

Add to your MCP client configuration (e.g., Claude Desktop, Cursor, or Claude Code):

{
  "mcpServers": {
    "cosmos-xrpl-bridge": {
      "command": "node",
      "args": ["/path/to/COSMOS-MCP-SERVER-BRIDGE-EXPERIMENT/dist/index.js"],
      "env": {}
    }
  }
}

Example Usage

Query Cosmos Account

// Tool: cosmos_get_account
{
  "address": "cosmos1..."
}

Bridge Tokens from Cosmos to XRPL

// Tool: bridge_cosmos_to_xrpl
{
  "cosmosAddress": "cosmos1...",
  "xrplAddress": "rN...",
  "amount": "100",
  "denom": "uatom"
}

Send XRP Payment

// Tool: xrpl_send_payment
{
  "destination": "rN...",
  "amount": "10",
  "memo": "Payment for services"
}

Bridge Workflow

Cosmos → XRPL Transfer

  1. Lock: Tokens are locked on Cosmos (sent to bridge address)
  2. Mint: Equivalent tokens are minted/released on XRPL
  3. Complete: Transfer marked as completed with both transaction hashes

XRPL → Cosmos Transfer

  1. Lock: XRP/tokens are locked on XRPL (sent to bridge address)
  2. Mint: Equivalent tokens are minted/released on Cosmos
  3. Complete: Transfer marked as completed with both transaction hashes

Security Considerations

⚠️ IMPORTANT: This is experimental software

  • Testnet First: Always test on testnet before mainnet
  • Key Management: Never commit private keys or mnemonics
  • Escrow Contracts: Production deployment requires proper escrow smart contracts
  • Audit Required: Get professional security audit before mainnet deployment
  • Limited Scope: Current implementation is simplified for demonstration
