# ERPNext MCP Server

A Model Context Protocol server for ERPNext integration

This is a TypeScript-based MCP server that provides integration with ERPNext/Frappe API. It enables AI assistants to interact with ERPNext data and functionality through the Model Context Protocol.

## Features

### Resources
- Access ERPNext documents via `erpnext://{doctype}/{name}` URIs
- JSON format for structured data access

### Tools
- `authenticate_erpnext` - Authenticate with ERPNext using username and password
- `get_documents` - Get a list of documents for a specific doctype
- `create_document` - Create a new document in ERPNext
- `update_document` - Update an existing document in ERPNext
- `run_report` - Run an ERPNext report
- `get_doctype_fields` - Get fields list for a specific DocType
- `get_doctypes` - Get a list of all available DocTypes

## Configuration

The server requires the following environment variables:
- `ERPNEXT_URL` - The base URL of your ERPNext instance
- `ERPNEXT_API_KEY` (optional) - API key for authentication
- `ERPNEXT_API_SECRET` (optional) - API secret for authentication

## Development

Install dependencies:
```bash
npm install
```

Build the server:
```bash
npm run build
```

For development with auto-rebuild:
```bash
npm run watch
```

## Installation

To use with Claude Desktop, add the server config:

On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
On Windows: `%APPDATA%/Claude/claude_desktop_config.json`

```json
{
  "mcpServers": {
    "erpnext": {
      "command": "node",
      "args": ["/path/to/erpnext-server/build/index.js"],
      "env": {
        "ERPNEXT_URL": "http://your-erpnext-instance.com",
        "ERPNEXT_API_KEY": "your-api-key",
        "ERPNEXT_API_SECRET": "your-api-secret"
      }
    }
  }
}
```

To use with Claude in VSCode, add the server config to:

On MacOS: `~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json`
On Windows: `%APPDATA%/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json`

### Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script:

```bash
npm run inspector
```

The Inspector will provide a URL to access debugging tools in your browser.
