Pump Fun MCP Server

Model Context Protocol server for the Pump SDK — 55 tools for token creation, trading, fees, analytics, and wallet management on Solana.

Overview

The MCP server exposes the full Pump Fun SDK as an AI-agent-compatible service using the Model Context Protocol (v2024-11-05). Any MCP-compatible client (Claude Desktop, Cursor, VS Code Copilot, custom agents) can call these tools to interact with the Pump protocol on Solana.

Configure in Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "pump-fun": {
      "command": "node",
      "args": ["/path/to/pump-fun-sdk/mcp-server/dist/index.js"],
      "env": {
        "SOLANA_RPC_URL": "https://api.mainnet-beta.solana.com"
      }
    }
  }
}

Configure in VS Code / Cursor

{
  "mcp": {
    "servers": {
      "pump-fun": {
        "command": "node",
        "args": ["./mcp-server/dist/index.js"],
        "env": {
          "SOLANA_RPC_URL": "https://api.mainnet-beta.solana.com"
        }
      }
    }
  }
}

Development

npm run dev    # Run with tsx (hot reload)
npm run lint   # Type-check without emitting
npm test       # Run vitest

Environment Variables

Security

• Key zeroization: All keypair material is zeroized on server shutdown and after each operation
• Private keys never exposed: Resource reads for keypairs only return public keys
• Ed25519 signing: Uses @noble/curves/ed25519 (audited, pure JS)
• Input validation: All tool inputs validated with Zod schemas
• Lazy SDK: RPC connection only created when an SDK tool is actually called
• No persistent storage: Keypairs exist only in server memory for the session duration
