Edwin MCP 服务器是一个为 Edwin SDK 实现的模型上下文协议（MCP）服务器示例，旨在通过标准化协议使 AI 代理与 Edwin 的工具进行交互。它支持多种区块链操作，如钱包操作、余额查询、交易签名、代币转账和合约交互。服务器需要在 Node.js 环境下运行，并依赖 Claude 实例或 API，以及 EVM 或 Solana 钱包私钥。安装和配置过程包括克隆仓库、安装依赖、构建项目以及设置环境变量。服务器可以在本地开发环境中运行，也可以与 Claude Desktop 集成使用。安全方面，强调了私钥保护和生产环境的安全设置。

README

Edwin MCP Server

This is an example implementation of a Model Context Protocol (MCP) server for the Edwin SDK. It allows AI agents to interact with Edwin's tools through a standardized protocol.

Prerequisites

Node.js >= 18.0.0
pnpm (recommended) or npm
A local Claude instance or access to Claude API
EVM and/or Solana wallet private keys (depending on your needs)

Installation

Clone the repository and navigate to the mcp-server directory:

cd examples/mcp-server

Install dependencies:

pnpm install

Build the project:

pnpm build

Running the Server

Option 1: Local Development

Create your environment file:

cp .env.example .env

Configure your .env file with the following required settings:
- SOLANA_RPC_URL: Your RPC endpoint
- EVM_PRIVATE_KEY: Your EVM wallet private key
- SOLANA_PRIVATE_KEY: Your Solana wallet private key
- EDWIN_MCP_MODE=true: Enable MCP mode
Start the server:
- For production: pnpm start
- For development with hot reloading: pnpm dev

Option 2: Using with Claude Desktop

After building the project, use the provided claude_desktop_config.json to configure your Claude Desktop:
- Open Claude Desktop
- Go to Settings
- Import the configuration from claude_desktop_config.json
The server will automatically start when needed by Claude Desktop.

Available Tools

The server exposes all tools configured in your Edwin instance. Common tools include:

Wallet operations
Balance checking
Transaction signing
Token transfers
Contract interactions

Security Considerations

Never commit your .env file with private keys
Use appropriate CORS settings in production
Implement rate limiting for production use
Keep your private keys secure and never share them

Troubleshooting

Server won't start:
- Check if the port is already in use
- Verify your environment variables are set correctly
- Check the logs for specific error messages
Tools not available:
- Ensure your Edwin instance is properly configured
- Check if the tools are properly registered
- Verify your wallet keys are correct
Connection issues:
- Check if the server is running
- Verify the port is correct
- Check network connectivity
