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

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
      }
    }
  }
}

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.
