+# MCP Inspector Development Guide
+
+## Build Commands
+
+- Build all: `npm run build`
+- Build client: `npm run build-client`
+- Build server: `npm run build-server`
+- Development mode: `npm run dev` (use `npm run dev:windows` on Windows)
+- Format code: `npm run prettier-fix`
+- Client lint: `cd client && npm run lint`
+
+## Code Style Guidelines
+
+- Use TypeScript with proper type annotations
+- Follow React functional component patterns with hooks
+- Use ES modules (import/export) not CommonJS
+- Use Prettier for formatting (auto-formatted on commit)
+- Follow existing naming conventions:
+  - camelCase for variables and functions
+  - PascalCase for component names and types
+  - kebab-case for file names
+- Use async/await for asynchronous operations
+- Implement proper error handling with try/catch blocks
+- Use Tailwind CSS for styling in the client
+- Keep components small and focused on a single responsibility
+
+## Project Organization
+
+The project is organized as a monorepo with workspaces:
+
+- `client/`: React frontend with Vite, TypeScript and Tailwind
+- `server/`: Express backend with TypeScript
+- `cli/`: Command-line interface for testing and invoking MCP server methods directly

 These buttons appear in the Inspector UI after you've configured your server settings, making it easy to save and reuse your configurations.
 
-For SSE transport connections, the Inspector provides similar functionality for both buttons. The "Server Entry" button copies the SSE URL configuration that can be added to your existing configuration file, while the "Servers File" button creates a complete configuration file containing the SSE URL for direct use in clients.

 You can paste the Server Entry into your existing `mcp.json` file under your chosen server name, or use the complete Servers File payload to create a new configuration file.
