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-mcp-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.
