KaiaFun MCP

🐍 ☁️ An MCP server for listing and trading tokens on KaiaFun and interacting with the Kaia blockchain

🛠️ MCP Server

Overview

The Model Context Protocol (MCP) is an open protocol that standardizes how applications provide context to Large Language Models (LLMs).

This repository implements an MCP server for the KaiaFun protocol, enabling token listing, trading, and interaction with the Kaia blockchain (e.g. checking token balances of configured wallet).

Installation

# Clone the repository
git clone https://github.com/weerofun/kaiafun-mcp
cd kaiafun-mcp

# Install dependencies
yarn

# Build
yarn build

The build process will generate output in the directory specified in tsconfig.json (dist as default) via tsc.

To start the MCP Server, you'll need to run dist/kaiafun-mcp-server.js (see #configuration below).

Configuration

Update your Claude Desktop configuration by updating claude_desktop_config.json:

{
  "mcpServers": {
    "kaiafun": {
      "command": "node",
      "args": ["/path/to/dist/kaiafun-mcp-server.js"],
      "env": {
        "PRIVATE_KEY": "0x"
      }
    },
    "puppeteer": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-puppeteer"]
    }
  }
}

• Set mcpServers.kaiafun.args[0] to the absolute path of dist/kaiafun-mcp-server.js
• Configure PRIVATE_KEY with the account's private key for transaction signing
• We also recommend adding @modelcontextprotocol/server-puppeteer to your configuration for basic web browsing capabilities

[!CAUTION] PLEASE NOTE that storing private key (PRIVATE_KEY) in plaintext is not safe, and this is primarily for development/exploration purposes.

🛠️ SDK

We are also working on a TypeScript SDK to interact with the KaiaFun protocol. It powers the core functionality of our MCP server and can later be used independently for building custom applications. Source code is located in the src/sdk directory.

Currently supported features are as follows:

• ✅ Listing new tokens with predefined metadata
• ✅ Buying and selling tokens with KAIA

Please note that the SDK is also in beta, and features and implementation are subject to change.
