A step-by-step guide to connecting Claude, ChatGPT, or Cursor to PlantPredict via the MCP connector
This feature requires a PlantPredict Pro or Enterprise subscription.
The PlantPredict MCP connector lets you work with PlantPredict directly from your AI assistant, in plain language. Once connected, you can ask it to create and run predictions, import weather and shade scenes, browse your projects, and read results — and it acts entirely as you, using your own PlantPredict account and permissions.Your AI assistant talks to a secure PlantPredict connector, which in turn calls the PlantPredict API on your behalf. You connect once, sign in with your PlantPredict account, and you are ready to go.This guide covers three AI tools: Claude, ChatGPT, and Cursor. Select the tab for the tool you use below. The sections at the end — What you can do with it, Good to know, If something goes wrong, and Need help? — apply to all three.
Use a Claude plan that supports custom connectors — Pro, Max, Team, or Enterprise. (The Free plan cannot add custom connectors.)
Make sure your PlantPredict company has connector access. An administrator must enable “Allow MCP Server Access For API Users,” and your company must have an active, qualifying subscription. Without both, Claude will connect but every action returns an “MCP access is not enabled” message.
Have your PlantPredict email and password ready — you sign in once during setup.

Menu names may vary slightly depending on your Claude plan and version, but the flow is the same.

Use a ChatGPT plan that supports custom connectors. Custom (MCP) connectors are available on paid plans; on Business and Enterprise workspaces an administrator may need to add or approve the connector first, and on some plans you enable connector or developer settings before the option appears. If you do not see it, check with your ChatGPT workspace administrator.
Make sure your PlantPredict company has connector access. An administrator must enable “Allow MCP Server Access For API Users,” and your company must have an active, qualifying subscription. Without both, ChatGPT will connect but every action returns an “MCP access is not enabled” message.

Use a recent version of Cursor. You can add PlantPredict with a one-click link, or by pasting one short entry into Cursor’s MCP configuration — both take under a minute and are shown below. On Business or Enterprise Cursor plans, an administrator may control which MCP servers are allowed, so check with them if the server is blocked.
Make sure your PlantPredict company has connector access. An administrator must enable “Allow MCP Server Access For API Users,” and your company must have an active, qualifying subscription. Without both, Cursor will connect but every action returns an “MCP access is not enabled” message.
Have your PlantPredict email and password ready — you sign in once during setup.

In Cursor, the New MCP Server button opens a configuration file (mcp.json) rather than a fill-in form. The quickest way to avoid touching that file is the one-click link in Option A; if you prefer to do it by hand, Option B shows the one entry to paste. Use either — you only need one.
Option A: One-click link
Option B: Add it by hand
Use the “Add to Cursor” link below to let Cursor add PlantPredict for you — no files to edit. Click the link, then click through the prompts.
Click the “Add to Cursor” link above, or paste it into your browser’s address bar.

Open Cursor Settings, go to Tools & MCPs, and click Add Custom MCP. Cursor opens the mcp.json file. Add the PlantPredict entry inside the mcpServers section, then save:
However you added it, PlantPredict requires you to sign in, so Cursor shows the server as needing authentication. Click Connect. Cursor opens a PlantPredict sign-in window — enter your PlantPredict email and password and approve access. Your password goes only to PlantPredict; Cursor never sees or stores it.

Turn it on and confirm
Once you approve, the server shows as connected (a green indicator) and the PlantPredict tools appear in its list. Make sure the PlantPredict server’s toggle is on.
The PlantPredict server connected and enabled in Cursor, with its tools listed.
Open Cursor’s Agent (the chat in Agent mode), make sure PlantPredict is enabled, and try a prompt such as:
“List my PlantPredict projects.”
“Create a new project in Berkeley, CA.”
“Create a 5 MW prediction in project <project-id>/<project-name> and run it.”
“Show the summary results for prediction <prediction-id>/<prediction-name>.”
Cursor’s Agent will call the PlantPredict tools to answer — you may be asked to approve each tool run — and you will see the results right in the chat.

It acts as you. Everything your AI assistant does runs under your PlantPredict account and permissions — nothing you could not do yourself.
Your password is never stored. Only short-lived access tokens are used after you sign in.
You may need to sign in again occasionally. If prompted, simply reconnect — this is expected.
Access is limited by region. Connections from US-sanctioned countries are intentionally blocked.
Claude — new tools appear in a new conversation. If you just connected and do not see PlantPredict tools, start a fresh conversation.
ChatGPT — turn the connector on in each chat. In a new chat, enable PlantPredict from the connectors or tools menu so ChatGPT can use it.
Cursor — use Agent mode. PlantPredict tools are available to Cursor’s Agent; a plain chat without the Agent will not call them.
Cursor — you may be asked to approve tool runs. Cursor can prompt before running a tool — approve to continue, or turn on auto-run in settings if you prefer.
"MCP access is not enabled for your organization."
Your company does not yet have connector access. Ask a PlantPredict administrator to enable “Allow MCP Server Access For API Users” and confirm your subscription is active.
"Authentication failed" or an invalid/expired token
In Claude or ChatGPT, disconnect and reconnect the PlantPredict connector — it will sign you in again and refresh automatically. In Cursor, open Tools & Integrations settings and click Login again (or turn the PlantPredict server off and back on).
You do not see the PlantPredict tools
Start a new conversation or chat with the connector turned on. In Cursor, make sure the PlantPredict server is turned on in settings and that you are using the Agent.
ChatGPT — you do not see the option to add a custom connector
Your plan or workspace may not have custom connectors enabled — check with your ChatGPT workspace administrator.
Cursor — the one-click link does not prompt anything
Use Option B instead — click New MCP Server and paste the entry into mcp.json.
Cursor — the server shows a red dot, "no tools," or will not connect
Check that the URL in mcp.json is exactly the connector address above, and that you completed the Login step for a green, connected status.
Access is blocked (error 403)
The connection is coming from a region where access is not permitted.
If you cannot connect or an action keeps failing, contact your PlantPredict administrator or PlantPredict support, and let us know what you were doing and the exact message you saw. We will look into it.
