Solana MCP Server

Solana MCP Server – Bringing Blockchain Operations into AI Workflows

The Solana MCP server solves a common pain point for developers building AI‑powered tools that need to interact with the Solana blockchain: securely and programmatically accessing wallet data, querying network state, and initiating token transfers without exposing private keys or managing RPC connections manually. By wrapping these actions behind a lightweight MCP interface, the server lets Claude and other AI assistants perform real‑world blockchain tasks directly from within a conversation.

At its core, the server exposes four simple yet powerful tools. The get‑latest-slot tool fetches the current blockchain slot, giving an AI assistant a sense of network progress. Get‑wallet-address and get‑wallet-balance provide quick access to the user’s Solana address and balance in SOL, lamports, and a USD estimate. Finally, the transfer tool executes a SOL transfer to any recipient address, returning detailed transaction metadata that can be displayed or logged by the assistant. These tools are intentionally minimalistic, reducing friction for developers while still covering the most common use cases.

Developers can integrate this server into their AI workflows in two straightforward ways. First, the server is available as a pre‑built package on Smithery, which automatically installs it for Claude Desktop. Second, the repository can be cloned and run locally, allowing full control over RPC endpoints and keypair storage. Once running, the server can be added to Cursor or any MCP‑compatible client by providing a command line that points to the executable and the keypair file. This flexibility means teams can keep sensitive keys on premises, switch between devnet and mainnet easily, or even orchestrate multiple wallet instances for testing.

Real‑world scenarios that benefit from this MCP include automated portfolio monitoring, where an AI assistant can report the latest balance and slot status on demand; cross‑chain trading bots that need to move SOL in response to market signals; or educational tools that demonstrate Solana operations within a conversational interface. Because the server returns rich JSON responses, developers can parse and format the data in any UI or downstream service, making it a versatile building block for hybrid AI‑blockchain applications.

What sets the Solana MCP apart is its emphasis on security and simplicity. By requiring only a local keypair file and exposing no RPC credentials, it eliminates common attack vectors that plague generic blockchain libraries. The concise tool set keeps the MCP surface area small, reducing maintenance overhead while still covering essential functionality. For developers looking to embed Solana interactions into AI assistants, this server offers a ready‑made, low‑friction bridge between the blockchain and conversational AI.
