PumpSwap MCP Server

An MCP server that enables AI agents to interact with PumpSwap for real-time token swaps and automated on-chain trading.

License Python Status

Features

  • Buy Tokens: Purchase tokens using SOL with customizable slippage and priority fees.
  • Sell Tokens: Sell tokens for SOL with configurable parameters.
  • Token Price Query: Retrieve current token prices in SOL.
  • Pool Data Retrieval: Fetch and display detailed pool information for a given token mint.

Prerequisites

  • Python 3.13 or higher
  • uv for dependency management and script execution
  • Solana RPC endpoint (e.g., https://api.mainnet-beta.solana.com)
  • A valid Solana private key for transaction signing

Installation

  1. Clone the Repository:

    git clone https://github.com/kukapay/pumpswap-mcp.git cd pumpswap-mcp
  2. Install uv: If uv is not installed, follow the official uv installation guide. For example:

    curl -LsSf https://astral.sh/uv/install.sh | sh
  3. Set Up Dependencies: Use uv to install dependencies:

    uv sync
  4. Configure Environment Variables: Create a .env.private filein the project root with the following variables:

    HTTPS_RPC_ENDPOINT=https://api.mainnet-beta.solana.com BUY_SLIPPAGE=0.3 SELL_SLIPPAGE=0.1 SWAP_PRIORITY_FEE=1500000 PRIVATE_KEY=your-solana-private-key

    Replace your-solana-private-key with your actual Solana private key.

Usage

Run the MCP Server

Use uv to run the server:

uv run main.py

The server will listen for MCP commands and expose the following tools:

  • buy_token(mint: str, sol_amount: float, user_private_key: str): Buy tokens with SOL.
  • sell_token(mint: str, token_amount: float, user_private_key: str): Sell tokens for SOL.
  • get_token_price(mint: str): Fetch the current token price in SOL.
  • get_pool_data(mint: str): Retrieve formatted pool data for a token.

Buy Tokens

Prompt:

Buy 0.1 SOL worth of tokens with mint address FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump.

This triggers buy_token("FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump", 0.1).

Expected Output:
