available standard Solana RPC methods that can be implemented with the current Solana client library (70 methods total).** +**The Solana MCP Server now implements ALL 91 possible Solana RPC methods and subscriptions!** -### Methods NOT implementable: -- **WebSocket subscription methods** (15 methods) - Cannot be implemented as they require WebSocket connections -- **Non-existent methods** (3 methods) - Methods that don't exist in the current Solana client library: - - `getSnapshotSlot` - - `getBlockCommitment` - - `getStakeActivation` +### Methods NOT implementable (and why): +- **0 methods** - Everything has been implemented! ### Full Implementation Status: - βœ… **Account Methods**: 11/11 implemented (100%) - βœ… **Block Methods**: 14/14 implemented (100%) -- βœ… **System

`solana-mcp-server web --port 3000` +3. **WebSocket Server**: `solana-mcp-server websocket --port 8900` + +### WebSocket Usage + +Connect to `ws://localhost:8900` and send JSON-RPC 2.0 messages: + +```javascript +// Subscribe to account changes +{ + "jsonrpc": "2.0", + "id": 1, + "method": "accountSubscribe", + "params": ["11111111111111111111111111111111"] +} + +// Subscribe to transaction

establishment timeout +- Message send/receive timeouts +- Subscription creation timeout +- Idle connection cleanup +- Ping/pong heartbeat mechanism + +### Error Handling + +When timeouts occur: +- HTTP requests return `408 Request Timeout` +- WebSocket connections are gracefully closed +- Failed subscriptions return JSON-RPC error responses +- All timeout events are logged with appropriate severity + +## Monitoring and Diagnostics + +Timeout events are exposed through: +- **Prometheus metrics**: `solana_mcp_rpc_requests_failed_total{error_type="timeout"}` +- **Structured logging**: JSON-formatted timeout logs +- **Health endpoint**: Connection and timeout status + +## Best Practices + +### Development +- Use shorter timeouts (5-15 seconds) for development +- Enable debug logging to monitor timeout behavior +- Test with network delays and poor connectivity + +### Production +- Use longer timeouts (30-60 seconds) for production stability +- Monitor timeout metrics for performance optimization +- Configure load balancer timeouts to exceed server timeouts + +### High-Load Environments +- Increase `max_idle_seconds` for persistent connections +- Reduce
