Argosvix

Argosvix is an observability MCP server that lets an assistant query LLM cost, error, and latency data and operate alerts and evals.

What you can do

Argosvix exposes an observability backend to an assistant over stdio. According to the registry description, it can query LLM cost, error, and latency data and operate alerts and evals. Two public data tools, get_synth_daily and get_daily_readthrough, are available without an API key, while account tools require one.

When to use it

Useful when you want an assistant to inspect LLM usage, spend, error rates, or latency, or to work with alerts and evaluations from a chat client such as Claude or Cursor. It is aimed at teams already using the Argosvix observability platform.

Requirements

Runs as a local stdio process on the user's machine, installed from the npm package @argosvix/mcp-server, so Node.js is needed. An Argosvix API key (ARGOSVIX_API_KEY, prefixed argk_) issued from the dashboard is required for account tools; without it only the two public data tools work. Desktop only.
