YG3 Marketing MCP — questions

Answers built from our own checks of this server.

Is YG3 Marketing MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 47 of 91 checks got a reply (51.6%), average response time 565 ms. The bar chart above shows every period we have measured.

The registry lists YG3 Marketing MCP 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 YG3 Marketing MCP?

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 YG3 Marketing MCP need an API key?

No. YG3 Marketing MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.

How fast is YG3 Marketing MCP?

It answers our handshake in 565 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 YG3 Marketing MCP open source?

The code is open source: it is published under the MIT licence, written in Shell and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.yg3.ai, which runs on its operator's own terms.
