solana-mcp-server

Full Solana blockchain MCP server. 25 tools for wallet management, SPL token operations, DeFi, staking, and network queries. Built on @solana/web3.js and @solana/spl-token with Anchor support.

The most actively maintained Solana MCP. Covers the complete SPL token lifecycle (create, mint, burn, freeze, thaw, delegate, authority management) that competitors skip.

Why This One?

• Complete SPL token lifecycle. Create, mint, burn, freeze, thaw, set authority, delegate, close -- 10 token tools covering every operation. Competitors stop at create/transfer.
• Production-ready infrastructure. Lazy connection initialization (no startup timeouts), 10-second network call timeouts, comprehensive error handling, and Smithery deployment support.
• Anchor integration. Built with @coral-xyz/anchor support for interacting with Anchor programs alongside raw SPL token operations.

Networks

Security

• Private keys stored in memory only -- never persisted to disk
• Keys cleared on process exit
• All inputs validated with Zod schemas
