⚙ Agent Friendliness
🔒 Security
HTTPS. No private keys in this MCP. Read-only blockchain queries. Official Solana Foundation. Public blockchain data — no PII.
⚡ Reliability
Best When
A developer building Solana applications needs AI assistance to query on-chain data, debug transactions, and explore the Solana ecosystem — official MCP from Solana Foundation.
Avoid When
You're building on Ethereum, Bitcoin, or other chains. For Solana transaction signing and wallet operations, use dedicated wallet libraries with proper key management.
Use Cases
- • Querying Solana account balances and token holdings from blockchain analysis agents
- • Fetching transaction details and status from debugging agents
- • Accessing Solana program (smart contract) metadata from development agents
- • Monitoring Solana network health and slot information from observability agents
- • Assisting with Solana program development and debugging from coding agents
- • Research and analysis of on-chain Solana data from analytics agents
Not For
- • Sending transactions or managing wallets (read-focused; sending requires private key management)
- • Non-Solana blockchains (use Ethereum, Bitcoin, or other blockchain MCPs)
- • Production trading systems requiring ultra-low latency and guaranteed delivery
Interface
Authentication
Public Solana RPC endpoint (no auth) or authenticated RPC via providers like Helius, Alchemy, QuickNode. Set SOLANA_RPC_URL environment variable. Mainnet, devnet, and testnet URLs available.
Pricing
Public Solana RPC is free but rate-limited. Premium RPC providers (Helius: free tier; Alchemy: free tier) provide better reliability. MCP server is free open source from Solana Foundation.
Agent Metadata
Known Gotchas
- ⚠ Public RPC rate limits are strict — use a premium RPC provider for production agent use
- ⚠ Solana account addresses are base58 encoded — ensure correct format in queries
- ⚠ On-chain data is immutable — historical queries are reliable but current state changes rapidly
- ⚠ Token accounts vs wallet accounts have different structures — understand account types
- ⚠ Official MCP from Solana Foundation — high quality and actively maintained
- ⚠ Never expose private keys to the MCP — this is for read operations; signing requires separate key management
