Solana Agent MCP is a tool that lets AI agents, like Claude, interact directly with the Solana blockchain. It works as an MCP (Model Context Protocol) server, which means it acts as a bridge between an AI assistant and the blockchain, letting the AI check balances, send SOL, swap tokens, and even trade memecoins on pump.fun, all through plain conversation instead of writing code. The setup runs entirely on your own computer. The AI agent talks to the server over a local connection (stdin and stdout), not over the network, and your private key, if you choose to add one, signs transactions locally and never leaves your machine. Without a private key, the tool still works in read only mode: checking balances, prices, and scanning for new tokens. There are 14 tools in total, split into read tools (checking balances, token info, prices, recent pump.fun tokens, transaction details) and write tools (sending SOL or tokens, swapping through Jupiter, buying or selling pump.fun tokens, requesting a devnet airdrop). Any transaction over 0.01 SOL requires explicit confirmation before it goes through, and every transaction returns a link to view it on Solscan. The tool also will not let your wallet trade below a small reserve balance. To use it, you clone the repository, install dependencies with npm, copy an example environment file, and add API keys from Helius (which are free) plus your Solana private key if you want live transactions. Once running, you type a slash command in Claude Code to open a guided setup wizard. This project would suit someone comfortable experimenting with crypto wallets and AI agents together, since it involves real transactions with real money once a private key is added. The license is AGPL 3.0, meaning you can use and modify the code freely, but if you run a modified version as a network service, you must share your changes publicly. Companies cannot take this code and turn it into a closed, paid product.
