Solana MCP Server

A Model Context Protocol (MCP) server that provides comprehensive access to Solana blockchain data through Cline. This server implements a wide range of Solana RPC methods, making it easy to query blockchain information directly through natural language conversations.

• "Show me the current slot number"
• "Get information about the latest block"
• "What's the current inflation rate?"
• "Show me the token accounts owned by address ..."
