Pump SDK MCP Server — Claude Code MCP server for Pump.fun on Solana
Gives your agent access to the Pump SDK: reads bonding curve state and prices buy and sell quotes for Solana tokens. Useful when you work with Pump.fun from the editor.
claude mcp add pump-fun-sdk -- npx -y pump-fun-mcpWhat Pump SDK MCP Server does
The server wraps the TypeScript SDK for the Pump.fun protocol on Solana. Through it the agent fetches token price, market cap, graduation progress, fees and AMM pool state. Buy and sell quotes are priced offline, including fees and price impact.
The SDK never sends transactions itself. It returns TransactionInstruction[] that you compose into a transaction with your own signing and sending strategy. Reading the chain needs no wallet and no API key, which matters if you would rather not hand private keys to a tool. Write operations need a Solana RPC endpoint.
The package runs through npx -y pump-fun-mcp, so there is nothing to install separately. If you use the SDK in your own code, it expects peer dependencies: @solana/web3.js, @solana/spl-token, @coral-xyz/anchor and bn.js.
What it helps with
- check a token price and graduation progress from the chat
- estimate how many tokens 1 SOL buys after fees
- inspect AMM pool state after migration
- build instructions for token creation and bonding curve trading
- configure fee sharing between creator and protocol
Example prompts for the agent
- Show the bonding curve state for mint
