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

{
  "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, which is available as a package script:

npm run inspector

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