Authenticated Llm Mcp Agent

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

This production-ready remote agent provides a secure and authenticated gateway to powerful Large Language Models. It leverages bcrypt and JSON Web Tokens (JWT) for robust access control, ensuring only authorized requests can execute LangChain-on-Vertex Gemini completions. Unauthenticated calls are automatically rejected, making it ideal for applications requiring secure LLM integration.

Designed for developers and enterprises, this agent speaks open A2A and MCP protocols, facilitating seamless integration into existing microservice architectures. Access is metered via x402 micropayments (discovery is free), offering a cost-effective and scalable solution for integrating advanced AI capabilities into your projects.

FAQ

How does authentication work for this LLM agent?

The agent uses bcrypt for initial user authentication and then issues JSON Web Tokens (JWTs). All subsequent API calls require a valid JWT for authorization. Unauthenticated requests are rejected.

What LLM capabilities does this agent provide?

This agent provides access to LangChain-on-Vertex Gemini completions. It acts as a secure proxy to leverage the power of Google's Gemini models through LangChain orchestrations.

How is usage priced and what does 'discovery free' mean?

Usage is metered via x402 micropayments, meaning you pay only for the completions you consume. 'Discovery free' implies that initial access and integration setup, without active LLM completions, does not incur charges.

How do I connect to this agent from my application?

You connect to the agent via its standard API endpoints, first authenticating with bcrypt to receive a JWT. This JWT must then be included in the headers of subsequent requests to the LLM gateway. The agent supports open A2A and MCP protocols for standardized communication.
