Open Agent Marketplace Lab missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Open Agent Marketplace Lab — questions

Answers built from our own checks of this server.

What can Open Agent Marketplace Lab do?
It exposes 2 tools, read directly from the server on our last check. Among them: marketplace_joining_instructions, marketplace_status. 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 Open Agent Marketplace Lab 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 1649 ms. The bar chart above shows every period we have measured.
How do I connect Open Agent Marketplace Lab?
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 Open Agent Marketplace Lab need an API key?
No. Open Agent Marketplace Lab completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
