MCPBridge: n8n Model Context Protocol Server for Gmail

Overview

### Overview MCPBridge exposes a standard Model Context Protocol (MCP) server endpoint in n8n, allowing local desktop AI assistants (Cursor IDE, Claude Desktop) to invoke Gmail actions securely without exposing private credentials. ### Workflow Logic - **MCP Protocol:** Handles tool invocation requests over secure HTTP endpoints. - **Gmail Automation:** Executes inbox search, email body reading, and custom HTML email dispatch upon model request.

The problem
