+    The MCP Chat plugin brings conversational AI capabilities directly into your Backstage environment. It leverages the Model Context Protocol (MCP)
+    to connect with various AI providers and external tools, enabling developers to interact with their infrastructure, catalogs, and external services
+    through natural language.
+
+    ## Features
+
+    - **Multi-Provider AI Support**: Works with OpenAI, Claude, Gemini, and Ollama - choose the AI provider that best fits your needs
+    - **Multi-Server Support**: Connect multiple MCP servers simultaneously (STDIO, SSE, Streamable HTTP) for diverse tool integration
+    - **Tool Management**: Browse and dynamically enable/disable tools from connected MCP servers through an intuitive interface
+    - **Rich Chat Interface**: Beautiful, responsive chat UI with full markdown support for formatted responses
+    - **Quick Setup**: Configurable QuickStart prompts for common use cases - get started with pre-built automation tasks
+
+    ## Supported AI Providers
+
+    The following AI providers and models have been thoroughly tested:
+
+    - **OpenAI** (`gpt-4o-mini`) - Fully tested, recommended for production use
+    - **Gemini** (`gemini-2.5-flash`) - Fully tested with excellent tool calling performance, free tier available
+    - **Ollama** (`llama3.1:8b`) - Tested, works well locally (larger models like `llama3.1:30b` recommended for better results)
+    - **Claude** - Supported with tool calling capabilities
