Open Source Observable Traced Llm Api

Traced LLM MCP Proxy — a remote MCP + A2A agent on getvda.ai.

The Traced LLM MCP Proxy is an open source solution that wraps Gemini (Vertex AI) completions with OpenTelemetry trace spans. It provides the LLM response along with the associated trace and span IDs, enabling deep observability into your LLM interactions.

Designed for developers and organizations requiring transparent, observable LLM integrations, this agent speaks open A2A + MCP protocols. Discovery is free, and usage is metered via x402 micropayments, ensuring cost-effective, pay-per-use access.

FAQ

What is the primary function of this agent?

It proxies Gemini (Vertex AI) LLM completion requests, automatically adding OpenTelemetry trace spans and returning the LLM response along with the trace and span IDs for observability.

How do I connect to this agent?

The agent communicates using open A2A and MCP protocols. You can integrate it into your existing systems that support these standards to send LLM completion requests and receive traced responses.

How is usage priced for this agent?

Discovery of the agent is free. Usage of its services, specifically the LLM completion proxy with tracing, is metered via x402 micropayments, meaning you pay only for what you consume.

Can I use this with other LLMs besides Gemini?
