### 🎯 **Autonomous Multi-Agent Workflow**

**The Challenges**:

- 📄 **Implementation Complexity**: Converting academic papers and complex algorithms into working code requires significant technical effort and domain expertise

- 🔬 **Research Bottleneck**: Researchers spend valuable time implementing algorithms instead of focusing on their core research and discovery work

- ⏱️ **Development Delays**: Product teams experience long wait times between concept and testable prototypes, slowing down innovation cycles

- 🔄 **Repetitive Coding**: Developers repeatedly implement similar patterns and functionality instead of building on existing solutions

**DeepCode** addresses these workflow inefficiencies by providing reliable automation for common development tasks, streamlining your development workflow from concept to code.

```bash
# 1. Install MCP servers globally
npm i -g @modelcontextprotocol/server-brave-search
npm i -g @modelcontextprotocol/server-filesystem

# 2. Find your global node_modules path
npm -g root
```

Then update your `mcp_agent.config.yaml` to use absolute paths:

```yaml
mcp:
  servers:
    brave:
      command: "node"
      args: ["C:/Program Files/nodejs/node_modules/@modelcontextprotocol/server-brave-search/dist/index.js"]
    filesystem:
      command: "node"
      args: ["C:/Program Files/nodejs/node_modules/@modelcontextprotocol/server-filesystem/dist/index.js", "."]
```

> **Note**: Replace the path with your actual global node_modules path from step 2.

#### 🔍 **Search Server Configuration (Optional)**

DeepCode supports multiple search servers for web search functionality. You can configure your preferred option in `mcp_agent.config.yaml`:

```yaml
# Default search server configuration
# Options: "brave" or "bocha-mcp"
default_search_server: "brave"
```

**Available Options:**
- **🔍 Brave Search** (`"brave"`):
  - Default option with high-quality search results
  - Requires BRAVE_API_KEY configuration
  - Recommended for most users

- **🌐 Bocha-MCP** (`"bocha-mcp"`):
  - Alternative search server option
  - Requires BOCHA_API_KEY configuration
  - Uses local Python server implementation

**API Key Configuration in mcp_agent.config.yaml:**
```yaml
# For Brave Search (default) - around line 28
brave:
  command: "npx"
  args: ["-y", "@modelcontextprotocol/server-brave-search"]
  env:
    BRAVE_API_KEY: "your_brave_api_key_here"

# For Bocha-MCP (alternative) - around line 74
bocha-mcp:
  command: "python"
  args: ["tools/bocha_search_server.py"]
  env:
    PYTHONPATH: "."
    BOCHA_API_KEY: "your_bocha_api_key_here"
```

> **💡 Tip**: Both search servers require API key configuration. Choose the one that best fits your API access and requirements.

### ⚡ **Step 2: Launch Application**

#### 🚀 **Using Installed Package (Recommended)**

```bash
# 🌐 Launch web interface directly
deepcode

# The application will automatically start at http://localhost:8501
```

#### 🛠️ **Using Source Code**

Choose your preferred interface:

##### 🌐 **Web Interface** (Recommended)
```bash
# Using UV
uv run streamlit run ui/streamlit_app.py
# Or using traditional Python
streamlit run ui/streamlit_app.py
```
<div align="center">
  <img src="https://img.shields.io/badge/Access-localhost:8501-00d4ff?style=flat-square&logo=streamlit&logoColor=white" alt="Web Access" />
</div>

##### 🖥️ **CLI Interface** (Advanced Users)
```bash
# Using UV
uv run python cli/main_cli.py
# Or using traditional Python
python cli/main_cli.py
```
<div align="center">
  <img src="https://img.shields.io/badge/Mode-Interactive_Terminal-9b59b6?style=flat-square&logo=terminal&logoColor=white" alt="CLI Mode" />
</div>

### 🎯 **Step 3: Generate Code**

1. **📄 Input**: Upload your research paper, provide requirements, or paste a URL
2. **🤖 Processing**: Watch the multi-agent system analyze and plan
3. **⚡ Output**: Receive production-ready code with tests and documentation
