# Connect ChatGPT Web **Use this private setup until the public SolarSENS plugin is available in the directory.** It connects the SolarSENS MCP server, signs in with the email AVA Asia allowed for you, and makes SolarSENS available in a **Work** conversation. This connection adds the SolarSENS tools but not the guided Skills. * **Outputs:** charts in the chat, plus Excel files, PDFs, and reports when your plan includes file creation. * **Check first:** your ChatGPT plan and workspace must allow custom MCP apps. See [OpenAI's custom app requirements](https://help.openai.com/en/articles/12584461-developer-mode-and-mcp-apps-in-chatgpt).

The two email addresses can be different. See [Sign in](https://ai.solarsens.co/docs/installation/sign-in.md). * Enter this server address: ``` https://mcp.solarsens.co/mcp ``` Sign in through the browser when prompted. Do not paste a password, access token, or client secret into a chat. ## Create the SolarSENS app In the current ChatGPT web UI: 1. Open **Plugins** from the sidebar. 2. Select **Add**, then **Add custom MCP server**. 3. Enter `SolarSENS` as the name. Select **Server URL**. Download the [SolarSENS app icon](https://ai.solarsens.co/assets/files/solarsens-icon-15ee57fb857ffc3f6266264c1c5f1c41.png) and upload it as the plugin icon. Use the `SolarSENS` name and this icon so you can find the plugin in ChatGPT. The supplied PNG is at least 256 × 256 pixels and no larger than 10 KB. 4. Enter the server URL above. Keep **OAuth** as the authentication method. 5. Do not open **Advanced OAuth settings**. ChatGPT discovers the managed OAuth configuration from the server URL. 6. Review ChatGPT's custom MCP warning. Select **I understand and want to continue**, then select **Create as a plugin**. The warning is the same for every custom app. SolarSENS only reads data, and ChatGPT gets only the Plant access of the SolarSENS account linked to your allowed email. ## Sign in and approve 7. On the plugin page, find the SolarSENS app and select **Connect**. 8. Verify your email through Cloudflare. If AVA Asia already approved the identity link, continue without a SolarSENS password. A personal account may show the secure first-time link page instead. 9. Return to ChatGPT. After you return, the plugin page shows the SolarSENS app without a **Connect** button. Select **Try in chat** to open a Web Work conversation. The page lists one SolarSENS app under **Apps** and no Skills. This connection adds the SolarSENS tools only. The guided Skills come with the SolarSENS plugin, which works in the [ChatGPT desktop app and Codex](https://ai.solarsens.co/docs/installation/chatgpt-plugin.md). If the secure link page asks for your own SolarSENS account, type the password there only. ChatGPT never sees it. A user mapped to a shared SolarSENS account does not need that shared password. SolarSENS checks your access before it returns any Plant data. ## Test the connection In the web composer, select **Work**, open **Plugins**, and select **SolarSENS**. Start with discovery: ``` List the SolarSENS Plants I can access. Show the name, code, and timezone of each Plant. ``` Then ask for a bounded read. Replace the text in square brackets with your own details: ``` Show daily performance for [Plant name] from [start date] to [end date]. Include yield, performance ratio, availability, timezone, and data coverage. ``` The response should name a Plant and show a visible tool-call indicator. Then ask for a chart. Replace the text in square brackets with your own details: ``` Show the power chart for [Plant name] yesterday. ``` ChatGPT shows an interactive chart in the conversation. See [See a chart in the chat](https://ai.solarsens.co/docs/guides/plant-analysis.md#see-a-chart-in-the-chat). If the assistant returns no Plant, the account is connected but has no mapped Plant scope. Contact AVA Asia. Do not try to gain access by typing a different Plant ID. ## Refresh the tools after a SolarSENS update ChatGPT keeps a copy of the SolarSENS tool list. It does not get the new list when SolarSENS adds or changes a tool. A new sign-in does not update the list. After a SolarSENS update, use **Settings → Plugins → SolarSENS → Manage app → Refresh tools**, then start a new chat. For the full steps, see [ChatGPT: Refresh tools](https://ai.solarsens.co/docs/troubleshooting.md#chatgpt-refresh-tools). ## If the connection fails | What you see | What to check | | ------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | OAuth is not supported | Confirm that the URL ends with `/mcp` and that you selected OAuth. | | The browser login succeeds but ChatGPT shows an error | Remove the connector and add it again so ChatGPT starts a fresh authorization flow. | | The connector connects but no Plants appear | Ask AVA Asia to check the SolarSENS account-to-Plant mapping. | | A Plant is forbidden | The Plant is outside the signed-in account scope.
