Solana Agent

_{Watch in HD (1080p, 45s)}

Your on-chain copilot. An MCP (Model Context Protocol) server that gives AI agents full read/write access to the Solana blockchain — check balances, send SOL, swap tokens via Jupiter, scan pump.fun tokens in real-time, and trade memecoins. All through natural conversation. No API keys shared with the agent.

The MCP server runs as a local process. AI agents connect via stdin/stdout (standard MCP protocol). Your private key signs transactions locally — it never leaves your machine. The agent never sees your key.

Installation

git clone https://github.com/KorroAi/solana-agent-mcp.git
cd solana-agent-mcp
npm install
cp .env.example .env

Edit .env:

HELIUS_API_KEYS=your-key-1,your-key-2    # Free at helius.dev
PRIVATE_KEY=your-phantom-base58-key       # Optional — for live transactions
SOLANA_MCP_PORT=8791                      # Default

npm run dev

Then type /solana in Claude Code. The wizard guides you.

Safety

• Local signing: Private key never leaves your machine
• Confirmation gate: Transactions >0.01 SOL require explicit confirmation
• Solscan links: Every transaction returns an explorer link
• Read-only by default: No wallet = no write access, everything still works
• No API keys shared: The agent communicates via local stdio, not over the network
• Balance guard: Won't trade below 0.01 SOL reserve

/solana — Slash Command

/solana
> check my balance          → "You have 0.112 SOL (~$8.90)"
> send 0.01 SOL to 7bN2...  → "Sending... confirmed! tx: 2PFCa..."
> scan pump.fun tokens      → "4 new tokens detected"
> swap 0.05 SOL to USDC     → "Best route: SOL→USDC via Jupiter"
> buy B1bN... for 0.02 SOL  → "Buy executed! pump.fun/coin/B1bN..."
