Solana MCP Server

A production-grade Model Context Protocol server for interacting with the Solana blockchain. Gives AI agents (Claude, Cursor, etc.) the ability to read chain data, execute transactions, swap tokens, manage wallets, and more.

38 tools across 7 modules: Wallet, SPL Tokens, DeFi, NFT, Programs, Analytics, Network.

Quick Start

npx @visioneth/solana-mcp@latest

Claude Desktop / Cursor

Add to your MCP configuration:

{
  "mcpServers": {
    "solana-mcp": {
      "command": "npx",
      "args": ["-y", "@visioneth/solana-mcp@latest"],
      "env": {
        "SOLANA_RPC_URL": "https://api.mainnet-beta.solana.com"
      }
    }
  }
}

For write operations (transfers, swaps, minting), add your private key:

{
  "env": {
    "PRIVATE_KEY": "your_base58_private_key",
    "SOLANA_RPC_URL": "https://api.mainnet-beta.solana.com"
  }
}

SSE Mode (Remote)

npx @visioneth/solana-mcp@latest --sse
# Server starts on http://localhost:3001

Prompts

Built-in prompts for common workflows:

  • analyze_wallet — Full wallet analysis

  • inspect_transaction — Transaction deep-dive

  • analyze_token — Token due diligence with risk score

  • portfolio_check — All holdings summary

  • swap_analysis — Pre-swap analysis

  • analyze_nft — NFT metadata analysis

  • analyze_program — Program investigation

  • token_research — Comprehensive token research

  • network_health — Network status dashboard

  • solana_overview — Full network overview

Safety

  • Write operations require explicit network specification — the server will never default to mainnet for transactions

  • Private key only needed for writes — read-only tools work without credentials

  • Confirmation prompts before executing state-changing operations

  • All amounts use human-readable UI values (not raw lamports)

Development

git clone https://github.com/visioneth/solana-mcp.git
cd solana-mcp
npm install
cp .env.example .env
npm run dev        # stdio mode
npm run dev:sse    # SSE mode

Environment Variables

Variable

PRIVATE_KEY

SOLANA_RPC_URL
