Development Quick Start

1. Installation
   ```shell
   # Clone the repository
   git clone https://github.com/Abiorh001/mcp_omni_connect.git
   cd mcp_omni_connect

   Create and activate virtual environment

   uv venv
   source .venv/bin/activate

   Install dependencies

   uv sync
   ```

2. Configuration
   ```shell
   # Set up environment variables
   echo "LLM_API_KEY=your_key_here" > .env

   Configure your servers in servers_config.json

   ```

3. Start Client
   shell # Start the client uv run src/main.py pr python src/main.py

Server Configuration Examples

{   
    "LLM": {
        "provider": "openai",  // Supports: "openai", "openrouter", "groq"
        "model": "gpt-4",      // Any model from supported providers
        "temperature": 0.5,
        "max_tokens": 5000,
        "top_p": 0
    },
    "mcpServers": {
        "filesystem-server": {
            "command": "npx",
            "args": [\
                "@modelcontextprotocol/server-filesystem",\
                "/path/to/files"\
            ]

🎯 Usage

Interactive Commands

• /tools - List all available tools across servers
• /prompts - View available prompts

• /prompt:<name>/<args> - Execute a prompt with arguments
  ```shell
  # Example: Weather prompt
  /prompt:weather/location=tokyo/units=metric

  Alternative JSON format

  /prompt:weather/{"location":"tokyo","units":"metric"}
  `` -/resources- List available resources -/resource:- Access and analyze a resource -/debug- Toggle debug mode -/refresh` - Update server capabilities

Prompt Management

# List all available prompts
/prompts

# Basic prompt usage
/prompt:weather/location=tokyo

# Prompt with multiple arguments depends on the server prompt arguments requirements
/prompt:travel-planner/from=london/to=paris/date=2024-03-25

# JSON format for complex arguments
/prompt:analyze-data/{
    "dataset": "sales_2024",
    "metrics": ["revenue", "growth"],
    "filters": {
        "region": "europe",
        "period": "q1"
    }
}

# Nested argument structures

    "price_range": {"min": 500, "max": 1000},
    "features": ["5G", "wireless-charging"],
    "markets": ["US", "EU", "Asia"]
}
