kukapay/pumpswap-mcp

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

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:

Buy successful for 0.1 SOL of token FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump
Transaction ID: <transaction-id>
Amount: <token-amount>
Token Price (SOL): <price>

Sell Tokens

Prompt:

Sell 1000 tokens of FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump.

This triggers sell_token("FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump", 1000).

Expected Output:

Sell successful for 1000 tokens of FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump
Transaction ID: <transaction-id>
Amount: <sol-amount>
Token Price (SOL): <price>

Get Token Price

Prompt:

What is the current price of the token with mint FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump?

This triggers get_token_price("FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump").

Expected Output:

The current price of token FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump is <price> SOL.

Get Pool Data

Prompt:

Show me the pool data for the token with mint FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump.

This triggers get_pool_data("FC988ZAKRPc26wefDAxcYWB8kgbJTH4Tg3qDvf7xpump").

Expected Output:

LP Mint: <lp-mint>
Pool Base Token Account: <base-account>
Pool Quote Token Account: <quote-account>
LP Supply: <supply>

Environment Variables

The server uses the following environment variables, loaded from .env.private:

Variable	Description	Default Value
HTTPS_RPC_ENDPOINT	Solana RPC endpoint URL	https://api.mainnet-beta.solana.com
BUY_SLIPPAGE	Slippage tolerance for buy transactions	0.3 (30%)
SELL_SLIPPAGE	Slippage tolerance for sell transactions	0.1 (10%)
SWAP_PRIORITY_FEE	Priority fee for transactions (in lamports)	1500000
PRIVATE_KEY	Solana private key for signing transactions	None (required)

Ensure PRIVATE_KEY is set, as the server will raise an error if it's missing.
