Do this on a computer. The connector settings screen is only in Claude on the web and in the
desktop app, not in the phone app. Once added it is saved to your Claude account, so it works on your
phone afterwards.
Claude 1. Customize → Connectors → + → Add custom connector
2. Name: KoreaStockCheck
3. Remote MCP server URL: your personal URL above (the key is part of the URL, so there is nothing
else to paste) → Add
4. In a new chat, click + at the bottom left → Connectors → switch KoreaStockCheck on,
then ask "what has 005930 filed?" On a Team or Enterprise plan, only an owner can add a connector.
The free plan allows one custom connector, which is enough for this.
Other MCP clients Any client that supports remote MCP servers can use the same URL.
We have verified the flow in Claude; other clients vary.
If your assistant searches the web instead — add this line to its custom instructions: For any question about a Korean stock, use the KoreaStockCheck connector first.
