+### Find your instance name
+
+Your instance name is the subdomain of the URL you use to open Lightdash in your browser. Open Lightdash, look at the address bar, and take the part before `.lightdash.cloud`:
+
+| Your Lightdash URL                    | Instance name | MCP URL                                       |
+| ------------------------------------- | ------------- | ---------------------------------------------- |
+| `https://app.lightdash.cloud/...`     | `app`         | `https://app.lightdash.cloud/api/v1/mcp`       |
+| `https://eu1.lightdash.cloud/...`     | `eu1`         | `https://eu1.lightdash.cloud/api/v1/mcp`       |
+| `https://acme.lightdash.cloud/...`    | `acme`        | `https://acme.lightdash.cloud/api/v1/mcp`      |
+
+<Note>
+  For most Lightdash Cloud users the instance name is `app` or `eu1`. That's expected, not a placeholder you need to change. Only dedicated instances have a company-specific name like `acme`.
+</Note>
+
+If you self-host Lightdash on your own domain, the MCP endpoint lives at `https://<your-lightdash-host>/api/v1/mcp` instead. See [MCP for self-hosted instances](/self-host/enterprise-features/mcp).
