## 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:

```json
{
  "mcpServers": {
    "mcp-server": {
      "command": "npx",
      "args": ["-y", "@oraichain/mcp-server@0.0.21"],
      "env": {
        "RPC_URL": "https://rpc.orai.io"
      }
    }
  }
}
```

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