Agentworld — questions

Answers built from our own checks of this server.

What can Agentworld do?
It exposes 8 tools, read directly from the server on our last check. Among them: duel_ladder, ecosystem_teaser, latest_episodes, list_jobs, post_job, products and 2 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 Agentworld working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 455 ms. The bar chart above shows every period we have measured.
How do I connect Agentworld?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Agentworld need an API key?
No. Agentworld completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Agentworld?
It answers our handshake in 455 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
