# 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): ```json { "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 } } } } ``` 2. 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. ## Development ### Prerequisites - Rust and Cargo - Solana CLI tools (optional, for testing) ### Building ```bash cargo build ``` ### Running ```bash cargo run ``` ## License MIT License
