Stellar Pilot — MCP Server for Stellar

Stellar Pilot bridges natural language and the Stellar blockchain. It's an MCP server that translates what you want to do into the exact CLI commands needed to do it.

Stop fighting with Stellar CLI syntax. The Stellar CLI has:

• 10+ main commands (contract, keys, tx, network...)
• 70+ subcommands with unique syntax
• Hundreds of flags and parameters to remember

Stellar Pilot lets you skip all that. Just say what you need:

• "create a new account" instead of stellar keys generate --network testnet --fund
• "deploy my contract" instead of stellar contract deploy --wasm path --source account --network...
• "send 100 XLM to Bob" instead of stellar tx new payment --destination G... --amount...

It translates natural language to proper CLI commands through MCP (Model Context Protocol), working seamlessly in AI assistants and IDEs.

🚀 Features

• 73+ CLI Tools: Complete integration with the official Stellar CLI
• Smart Contract Operations: Deploy, invoke, build, and optimize Soroban contracts
• Transaction Management: Send payments, create accounts, manage trustlines, DEX trading
• Identity & Key Management: Generate keys, manage accounts, fund testnet accounts
• Network Configuration: Switch between testnet, mainnet, futurenet, and local networks
• Type-Safe Interface: Full TypeScript support with schema validation

📋 Prerequisites

• Node.js 18+ - Check with node --version

• Stellar CLI - Check with stellar --version

  If not installed, see: https://github.com/stellar/stellar-cli

📦 Installation

npm install -g stellarpilot

⚙️ Configuration

Add to your MCP settings:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "stellarpilot": {
      "command": "stellar-pilot"
    }
  }
}

Successful Configuration: Once properly configured, you'll see StellarPilot with 73 tools enabled in your MCP Tools panel:

🎯 Basic Usage Examples

Once configured, you can use natural language to interact with Stellar:

Account Management

"Generate a new account called alice"
"Fund alice's account on testnet"
"Show me alice's public key"
"Switch to using alice as default"

Example: Creating a New Account

StellarPilot automatically:

• Generates a new keypair with secure seed phrase
• Funds the account on testnet
• Stores credentials securely in local configuration
• Lists all your accounts with their details

Payments

"Send 100 XLM from alice to GDEXAMPLE..."
"Create a trustline for USDC:GCKFBEIYTKP..."
"Send 50 USDC from alice to bob"

Smart Contracts

"Deploy my contract from ./contract.wasm"
"Call the hello function on contract C123..."
"Build the contract in ./my-project"

Network Operations

"Switch to testnet"
"Check network health"
"Add a custom network called mynet"

🚨 Troubleshooting

Common Issues

1. "stellar command not found"

   • Install Stellar CLI: https://developers.stellar.org/docs/tools/developer-tools
   • Verify with stellar --version

2. "stellar-pilot command not found"

   • For global install: npm install -g stellarpilot
   • For local build: Use absolute path in MCP config

3. "Permission denied"

   • Check file permissions: chmod +x build/index.js
   • For global install: May need sudo npm install -g stellarpilot

4. "Tools not loading in Claude"

   • Restart your IDE or IDE plugin after config changes
   • Be sure you are using the correct config syntax
   • Verify file paths are absolute
