MCP SuperAssistant is a Chrome extension that bridges the gap between web-based AI assistants and the Model Context Protocol (MCP), enabling users to execute MCP tools directly within platforms like ChatGPT, Perplexity, and Gemini. It empowers users to seamlessly integrate real-time data and system interactions into their AI conversations, enhancing the utility of AI assistants for complex tasks.

How It Works

The extension operates by detecting MCP tool calls within AI responses. These detected calls are then sent via Server-Sent Events (SSE) to a local proxy server, which forwards them to the actual MCP server. Results are returned through the proxy to the extension, which then inserts them back into the AI chat interface. This architecture allows for flexible integration with various MCP server setups, including remote servers and those requiring CORS support.

Quick Start & Requirements

• Installation: Add from the Chrome Web Store.
• Local Proxy: Run npx @srbhptl39/mcp-superassistant-proxy@latest --config ./mcptestconfig.json.
• Prerequisites: Node.js (v16+), pnpm.
• Connection: Connect the extension to the local proxy via the sidebar UI by entering the proxy URL (default: http://localhost:3006).
• Docs: Demo Video

Highlighted Details

• Supports multiple AI platforms including ChatGPT, Perplexity, Gemini, and Grok.
• Features a sidebar UI for unobtrusive integration and tool execution.
• Offers auto-execute and auto-submit modes for streamlined workflows.

Limitations & Caveats

The extension relies on a separate local proxy server for MCP communication, requiring an additional setup step. Support for additional AI platforms is ongoing.
