The FlexWash MCP server gives ChatGPT read access to your FlexWash reports. Instead of building a report, you ask a question:
  • “How many memberships did we sell at each site last week?”
  • “Which site had the highest churn last month, and why?”
  • “Compare wash counts and revenue this month to the same month last year.”
  • “Which employees gave the most no-charge washes this week?”
ChatGPT picks the right FlexWash reports, runs them, and explains the results.

​
Requirements

  • A FlexWash admin account. Only admin users can connect. ChatGPT sees the same car washes and data you can see in FlexWash.
  • A ChatGPT plan that allows custom MCP servers. On a ChatGPT Business or Enterprise workspace, your workspace admin must allow plugins with custom MCP servers. Otherwise ChatGPT reports that your workspace doesn’t permit them.
The FlexWash MCP server is read-only. ChatGPT can run FlexWash reports, but it cannot change memberships, customers, prices, or any other data.

​
Ask a Question

Start a new chat, type @, and select FlexWash. Then ask about your car wash.
Name the time period and sites in your question, for example “last week at the Main Street location”. ChatGPT runs faster, more focused reports when it doesn’t have to guess.

​
Usage Limits

Each question can run several FlexWash reports. To protect performance, each user can run up to 30 reports per minute and 1,000 reports per day. If you reach a limit, ChatGPT tells you how long to wait.

​
Disconnect

Open chatgpt.com/plugins, select FlexWash under Installed, and disconnect it. To stop all access immediately, ask your FlexWash administrator to remove or downgrade your FlexWash user.

​
Troubleshooting

ChatGPT processes the report results you ask about under your OpenAI account’s terms. If Improve the model for everyone is on in your ChatGPT data controls, OpenAI may use that information to train its models. Review your data controls before connecting.
