Authenticated Llm Mcp Agent

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

This production-ready remote agent provides a robust and secure gateway for accessing Large Language Models. It leverages Bcrypt and JWT for stringent authentication, ensuring that only authorized requests can trigger LangChain-on-Vertex Gemini completions. Unauthenticated calls are automatically rejected, guaranteeing controlled access to your LLM resources.

Designed for developers and organizations requiring secure, metered LLM interactions, this agent speaks both open A2A and MCP protocols. It's built to integrate seamlessly into existing microservices architectures, with metering handled via x402 micropayments for cost-effective usage. Discovery of the agent itself is free.

FAQ

How do I authenticate with this LLM agent?

You authenticate using either Bcrypt credentials for initial access or a valid JWT (JSON Web Token) for subsequent, authorized requests. Unauthenticated requests are rejected.

What LLM is this agent using?

This agent utilizes Google's Gemini model via LangChain on Vertex AI for its language model completions.

How is pricing handled for LLM usage?

LLM usage is metered via x402 micropayments. Discovery of the agent itself is free, and you only pay for the actual LLM completions you consume.

How do I connect to this agent and send requests?

You can connect to this agent using standard open A2A or MCP protocols. Once authenticated, you can send your LLM completion requests, which will be processed by LangChain on Vertex Gemini.
