## What is MCP?
The Model Context Protocol (MCP) is an open standard developed by Anthropic that connects AI assistants to systems where data actually lives, including content repositories, business tools, and development environments. It serves as a universal protocol that enables AI systems to securely and dynamically interact with data sources in real time.

- **Plugin Architecture**: Modular plugin system with site-specific adapters for tailored platform integration
- **Sidebar UI**: Clean, unobtrusive interface that integrates with the AI platform
- **Tool Detection**: Automatically detects MCP tool calls in AI responses
- **Tool Execution**: Execute MCP tools with a single click
- **Tool Result Integration**: Seamlessly insert tool execution results back into the AI conversation
- **Render Mode**: Renders Function call and Function results.
- **Auto-Execute Mode**: Automatically execute detected tools
- **Auto-Submit Mode**: Automatically submit chat input after result insertion
- **Push Content Mode**: Option to push page content instead of overlaying

### Connecting to Local Proxy Server
To connect the Chrome extension to a local server for proxying connections:
#### Run MCP SuperAssistant Proxy via npx:
```bash
npx @srbhptl39/mcp-superassistant-proxy@latest --config ./config.json
```
This is useful for:
- Proxying remote MCP servers
- Adding CORS support to remote servers
- Providing health endpoints for monitoring
Use existing MCP config file if available.
```
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
```
**Example config.json:**
```json
{
"mcpServers": {
"desktop-commander": {
"command": "npx",
"args": [
"-y",
"@wonderwhy-er/desktop-commander"
]
}
}
}
```
#### Connection Steps:
1. Start the proxy server using one of the commands above
2. Open the MCP SuperAssistant sidebar in your AI platform
3. Click on the server status indicator (usually showing as "Disconnected")
4. Enter the local server URL (default: `http://localhost:3006/sse`)
5. Click "Connect" to establish the connection
6. The status indicator should change to "Connected" if successful
## Usage
1. Navigate to a supported AI platform.
2. The MCP SuperAssistant sidebar will appear on the right side of the page
3. Configure your MCP server by clicking on the server status indicator
4. Interact with the AI and use MCP tools by:
- Waiting for the AI to suggest a tool (auto-detected)
- Executing the tool via the sidebar
- Viewing the result and inserting it back into the conversation
## Tips & Tricks
1. **Turn off search mode** (chatgpt, perplexity) in AI chat interfaces for better tool call prompt experience and to prevent MCP SuperAssistant from getting derail.
2. **Turn on Reasoning mode** (chatgpt, perplexity, grok) in AI chat interfaces, which will help the AI to understand the context better and generate the correct tool calls.
3. Use newer high-end models as they are better at understanding the context and generating the correct tool calls.
4. Copy the MCP instructions prompt and paste it in the AI chat system prompt (Google AI Studio).
5. Mention the specific tools you want to use in your conversation.
6. Use the MCP Auto toggles to control the tool execution.
