Project Structure

This is a monorepo using Turborepo and pnpm workspaces. Here's the structure:

• packages/
  • mcp-server/: The core MCP server implementation
  • agent-tools/: Collection of blockchain interaction tools for AI agents
  • agent-kit/: Development kit for building AI agents with blockchain capabilities

Each package serves a specific purpose:

MCP Server

The main server package that implements the Model Context Protocol for blockchain interactions. It provides the core functionality for handling requests from AI clients.

Agent Tools

A collection of tools specifically designed for AI agents to interact with various blockchain networks. These tools are used by the MCP server to execute blockchain operations.

Agent Kit

A development kit that helps developers build AI agents with blockchain capabilities. It includes utilities, types, and interfaces for consistent agent development.

Integration with AI Tools

Claude Desktop Integration

To add this MCP server to Claude Desktop:

1. Create or edit the Claude Desktop configuration file at:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
   • Linux: ~/.config/Claude/claude_desktop_config.json

2. Add the following configuration:

{
  "mcpServers": {
    "mcp-server": {
      "command": "npx",
      "args": ["-y", "@oraichain/[email protected]"],
      "env": {
        "RPC_URL": "https://rpc.orai.io"
      }
    }
  }
}

3. Restart Claude Desktop for the changes to take effect.
