Extend Dexto's capabilities by adding your own Model Context Protocol (MCP) servers with new tools and data sources.

## What it does

Add custom MCP servers to:
- Connect new tools and APIs
- Access external data sources
- Integrate third-party services
- Build custom functionality

## How to add MCP servers

### Option 1: Via Web UI

```bash
# Launch the Web UI
dexto
```

1. Click on "MCP Servers" in the sidebar
2. Click "Add Server"
3. Enter server configuration
4. Save and the server tools become available immediately

### Option 2: Via agent.yml

Edit your agent configuration file:

```yaml
# agents/my-agent.yml
mcpServers:
  custom-server:
    type: stdio
    command: npx
    args: ['-y', 'your-mcp-server-package']
    env:
      API_KEY: $YOUR_API_KEY
```

### Option 3: Via CLI

```bash
# Edit agent config directly
nano ~/.dexto/agents/your-agent.yml

# Or use the coding agent config
nano ~/.dexto/agents/coding-agent/coding-agent.yml
```

## Example: Adding Brave Search

```yaml
mcpServers:
  web-search:
    type: stdio
    command: npx
    args: ['-y', '@modelcontextprotocol/server-brave-search']
    env:
      BRAVE_API_KEY: $BRAVE_API_KEY
```
