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.

Features

The server provides 21 essential Solana RPC methods across different categories:

Account & Balance Operations

• get_sol_balance: Get SOL balance for an address
• get_token_balance: Get SPL token balance
• get_account_info: Get account information
• get_largest_accounts: Get largest accounts on network

Block & Transaction Information

• get_slot: Get current slot
• get_block: Get block information
• get_block_time: Get block production time
• get_transaction: Get transaction details
• get_recent_blockhash: Get recent blockhash

Token Operations

• get_token_accounts_by_owner: Get token accounts by owner
• get_token_accounts_by_delegate: Get delegated token accounts
• get_token_supply: Get token supply information

System Information

• get_epoch_info: Get current epoch information
• get_version: Get node version
• get_health: Get node health status
• get_supply: Get current supply
• get_inflation_rate: Get inflation rate
• get_cluster_nodes: Get cluster node information
• get_minimum_balance_for_rent_exemption: Get minimum rent-exempt balance

Staking & Governance

• get_vote_accounts: Get vote accounts
• get_leader_schedule: Get leader schedule

Setup in Cline

1. Add the following configuration to your Cline MCP settings file (~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json on macOS):

{
  "mcpServers": {
    "solana": {
      "command": "cargo",
      "args": ["run"],
      "cwd": "/path/to/solana-mcp-server",
      "env": {
        "SOLANA_RPC_URL": "https://api.mainnet-beta.solana.com"  // Or your preferred RPC endpoint
      }
    }
  }
}

1. Restart Cline to load the new MCP server.

Usage Examples

Once configured, you can interact with the Solana blockchain through natural language in Cline. Here are some example queries:

• "What's the SOL balance of address Gh9ZwEmdLJ8DscKNTkTqPbNwLNNBjuSzaG9Vp2KGtKJr?"
• "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 ..."

Environment Variables

• SOLANA_RPC_URL: (Optional) The Solana RPC endpoint to use. Defaults to "https://api.mainnet-beta.solana.com" if not specified.
