A2A Authenticated Llm Service

Authenticated LLM Agent (Bcrypt) — a remote MCP + A2A agent on getvda.ai.

Our production-ready remote MCP/A2A agent provides a secure and authenticated LLM service. It acts as a JWT-gated gateway, authenticating users via bcrypt or JWT before executing LangChain-on-Vertex Gemini completions. Unauthenticated requests are automatically rejected, ensuring secure access to your AI models.

This agent speaks open A2A + MCP protocols, making it interoperable with existing systems. It's designed for developers and enterprises requiring robust, auditable, and metered access to LLM capabilities, with discovery being free and usage metered via x402 micropayments.
