Connecting a Solana Wallet to Claude
Great_Study_598 · reddit · 2026-07-11
The author created an open-source MCP server to connect a Claude Agent to a Solana wallet—locally generated with private keys never leaving the machine—allowing it to perform on-chain operations directly via natural language.
Capabilities
- Create wallets, view addresses and balances
- Search for tokens on launchpads
- Buy / sell tokens
- Launch custom tokens
- Withdraw SOL back to a Phantom address
Design Highlights
- Private keys are generated locally in /.agentpump/wallet.json
- Private keys are never sent to the model or any server
- Transactions are broadcast to the chain only after actual signing
- Single-file index.js allows direct source code review
Usage
- Provides installation via claude mcp add agentpump -- npx -y agentpump-mcp
- Also supports MCP clients like Cursor
- Claude Code and Cursor can execute these transaction tools
- Claude Desktop rejects signing financial transactions, so the author recommends using Code/Cursor
The author also mentioned that the tool has web and Telegram bot versions, cautioning that this involves real mainnet funds and users should start with very small amounts.
