Openpump

Go to openpump.io and sign up for an account. Once registered, navigate to the Settings page to generate your API key. The key will begin with op_sk_live_ and is required for all SDK and MCP server calls.

Run the OpenPump MCP initializer via npx. This command sets up the MCP server configuration so that your AI client can communicate with pump.fun through the OpenPump infrastructure.

npx @openpump/mcp init

If you want to use OpenPump programmatically in a Node.js project outside of an MCP client, install the SDK package.

npm install @openpump/sdk

Open your Claude Desktop (or other MCP client) configuration file and add the OpenPump server entry with your API key set as an environment variable.

{
  "mcpServers": {
    "openpump": {
      "command": "npx",
      "args": ["@openpump/mcp"],
      "env": {
        "OPENPUMP_API_KEY": "op_sk_live_YOUR_KEY_HERE"
      }
    }
  }
}

After saving the configuration, restart Claude Desktop (or your MCP client) so it picks up the new server. You should see OpenPump tools available in the tool list.

Use the MCP tools or SDK to create a token or execute a buy order on pump.fun. With the SDK, you can also automate these operations in CI pipelines or trading bots.

import { OpenPump } from '@openpump/sdk';
const client = new OpenPump({ apiKey: 'op_sk_live_...' });

await client.tokens.create({
  name: 'My Token',
  symbol: 'MTK',
  description: 'A new token on pump.fun',
});

await client.trading.buy({
  mint: 'TOKEN_MINT_ADDRESS',
  walletId: 'your-wallet-id',
  amountSol: 0.1,
});
