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

[dolphin-mcp]
servers_json = config/mcp_config.json
```

```json
{
    "mcpServers": {
        "example-server": {
            "command": "uvx",
            "args": ["mcp-server-example"],
