+
+A powerful chat application built with Streamlit that integrates with OpenAI's API and Model Context Protocol (MCP) for enhanced tool capabilities.
+
+## Features
+
+- 💬 Interactive chat interface with Streamlit
+- 🧠 OpenAI API integration with model selection
+- 🛠️ MCP server management and tool integration
+- ⚡ Both streaming and non-streaming response modes
+- 🔄 Automatic tool discovery and invocation
+
+## Installation
+
+1. Clone the repository:
+```bash
+git clone https://git.bhakat.dev/abhishekbhakat/mcpapp.git
+cd mcpapp
+```

+
+## Configuration
+
+1. Copy the sample config files:
+```bash
+cp config/sample_config.ini config/config.ini
+cp config/sample_mcp_config.json config/mcp_config.json
+```
+
+2. Edit `config/config.ini` with your OpenAI API key and preferences:
+```ini
+[openai]
+api_key = your_api_key_here
+base_url = https://api.openai.com/v1
+model = gpt-3.5-turbo
+
