LMX Cloud LLM Inference — questions

Answers built from our own checks of this server.

What can LMX Cloud LLM Inference do?

It exposes 9 tools, read directly from the server on our last check. Among them: chat_completion, extract_pdf, get_balance, get_pricing, get_status, get_usage and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is LMX Cloud LLM Inference working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 390 ms. The bar chart above shows every period we have measured.

How do I connect LMX Cloud LLM Inference?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does LMX Cloud LLM Inference need an API key?

No. LMX Cloud LLM Inference completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is LMX Cloud LLM Inference?

It answers our handshake in 390 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
