GAIP Listing Observer — questions

Answers built from our own checks of this server.

What can GAIP Listing Observer do?

It exposes 1 tools, read directly from the server on our last check. Among them: gaip_observe_listing. 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 GAIP Listing Observer working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 6 of 91 checks got a reply (6.6%), average response time 622 ms. The bar chart above shows every period we have measured.

The registry lists GAIP Listing Observer as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect GAIP Listing Observer?

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 GAIP Listing Observer need an API key?

No. GAIP Listing Observer completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is GAIP Listing Observer?

It answers our handshake in 622 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is GAIP Listing Observer open source?

The code is open source: it is published under the MIT licence, written in Python and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at gaipagents.com, which runs on its operator's own terms.
