Call again any time to check progress. (needs a token)

Tester Exchange — questions
Answers built from our own checks of this server.
What can Tester Exchange do?
It exposes 17 tools, read directly from the server on our last check. Among them: about, add_app, add_testers, buy_credits_links, campaign_report, fill_from_exchange and 11 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 →
What is Tester Exchange mostly used for?
Its tools cluster around start, testers and campaign. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Tester Exchange 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 175 ms. The bar chart above shows every period we have measured.
Did Tester Exchange ever remove tools?
Yes. join_swap_circle, leave_swap_circle, my_swap_circle, swap_circle_status and 2 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Tester Exchange?
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 Tester Exchange need an API key?
No. Tester Exchange completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 17 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Tester Exchange?
It answers our handshake in 175 ms on average, which is faster than 81% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
