This is a Google OAuth-protected gateway for running Gemini completions through Vertex AI. You pass in a Google ID token, it verifies your identity, then forwards your prompt to Gemini and returns the response. It's part of the GOSCE agent portfolio, which auto-generates monetizable MCP agents from open-source package combinations. The server runs remotely on getvda.ai with metered x402 micropayments and speaks both MCP and A2A protocols over streamable HTTP. Reach for this when you need authenticated LLM access with built-in identity verification, or when you want to keep API keys server-side while still controlling who can use them.
