This proof-of-concept MCP server integrates with the Solana blockchain to enable paid access to digital content and resources using direct SOL payments. It is built for developers exploring decentralized, permissionless access control systems that combine MCP with blockchain payment verification.
How to use MCP Solana Internet: Direct SOL Payments for Content Access?
Install Python 3.11+, Poetry, Solana CLI, and solana-test-validator. Clone the repository, run poetry install, and configure a .env file with RPC_ENDPOINT and PAYMENT_WALLET_SEED. Start the local test validator, then launch the server with poetry run python mcp_solana_internet/server.py. An MCP client checks access via the access://check resource, obtains a solana-action: payment URL, creates an unsigned transaction, signs it client-side, submits it to Solana, and finally calls the process_payment tool with the transaction signature.
