+[Add the DFO to Claude](https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=DFO&connectorUrl=https%3A%2F%2Fdevelopmentfinance.org%2Fmcp). The link opens Claude with the connector's name and address filled in, and you confirm.

+
+Open [Plugins](https://chatgpt.com/plugins) in ChatGPT, select **+**, then **Add custom MCP server**. Name it DFO, paste the address under **Connection**, choose **No authentication**, and select **Create as a plugin**.
+
+::tab{label="Gemini"}
+
+Open [Connected Apps](https://gemini.google.com/apps) in Gemini on the web, select **Add a custom app**, paste the address, and select **Next**. Custom apps need a personal Google account held by someone in the US aged 18 or over. On Gemini Enterprise, a team administrator can add the server for the team.
