Read this before you start
Every user can connect their account. You no longer need to be an administrator: your personal connection link is in your Hexfit Settings, under the “AI Assistant” tab.
Hexfit does not appear in the list of existing connectors, tools or plugins. Don’t look for it: you need to create a new custom connector yourself (also called an “MCP server”, “tool” or “custom app”) and paste your link into it.
Authentication must always be set to “None” (no authorization). Hexfit does not require OAuth, a Client ID or an API key.
Connect Hexfit to ChatGPT
Copy your connection link from your Hexfit Settings, under the “AI Assistant” tab.
Open ChatGPT.
Click your profile picture at the bottom left, then Settings.
Click “Apps” (plugins).
Click “Developer mode”.
Turn on “Developer” mode.
Go back to the “Apps” tab.
Click “Browse apps”.
Click the + and then “MCP server” to create a new custom app. Don’t look for Hexfit in the list of existing apps.
10. Enter the following information:
Name: Hexfit
Connection: paste your connection link
Authentication: None
11. That’s it! It works now 😁
Here is an example prompt you can use to test it (copy-paste or dictate):
“I want you to create a first workout directly in my Hexfit account, for the client [client name].
Name the workout “Test workout - Arms”.
Create a superset with 3 sets made of the following two exercises:
Dumbbell Biceps curl: 3 sets of 12 reps.
Push-ups: 3 sets of 12 reps.
Plan 60 seconds of rest after each superset.
Search for the client and the exercises in Hexfit, then create the workout in a new training program named “AI test program”.
Check that the exercises and their parameters were saved correctly. Leave the program as a draft without publishing it, so I can review it before making it visible to the client.
If essential information is missing or an action is not available, tell me clearly instead of assuming everything was done.”
Connect Hexfit to Claude
Copy your connection link from your Hexfit Settings, under the “AI Assistant” tab.
Open Claude.
Click “Customize” at the top left.
Go to “Connectors”.
Click “Add” at the top right to create a new custom connector. Hexfit is not one of the connectors offered by Claude, so there is no need to look for it in the list.
Name: Hexfit
URL: paste your connection link.
Authentication: select “None”. Leave the OAuth Client ID and Client Secret fields empty.
Connect Hexfit to Microsoft Copilot
Before you start: at Microsoft, an MCP server is added to an agent created in Microsoft Copilot Studio. You need a work Microsoft 365 account with access to Copilot Studio (and a Microsoft 365 Copilot license to use the agent in Copilot or Teams). The free version of Copilot (copilot.microsoft.com) does not let you add a custom MCP server.
Copy your connection link from your Hexfit Settings, under the “AI Assistant” tab.
Open Copilot Studio and sign in with your Microsoft 365 account.
Create a new agent (for example “Hexfit Assistant”) or open an existing one.
Go to the “Tools” tab, then click “Add a tool”.
Select “Model Context Protocol” to create a new custom tool.
Enter the following information:
Name: Hexfit
Description: Lets me view and create training programs, meal plans, recipes and forms for my clients in Hexfit
Server URL: paste your connection link
Authentication: None
Click “Create”, then under “Connection”, choose “Create a new connection” and click “Add and configure”.
Test the agent in the “Test” pane. The first time, click “Open connection manager”, then “Connect”, and run your request again.
To use it every day, click “Publish”, then turn on the Microsoft 365 Copilot and Teams channel. Depending on your organization’s rules, an administrator may need to approve the agent.
That’s it! You can use the same example prompt as above to test it 😁
Connect Hexfit to Gemini
Before you start: according to Google, adding custom apps (MCP servers) in Gemini is currently limited to personal Google accounts (not work or school accounts), users aged 18 and over located in the United States, and the interface is in English. Gemini’s activity setting (“Keep Activity”) must be turned on. Adding it can only be done on the web, but Hexfit will then also be available in the Gemini mobile app.
Copy your connection link from your Hexfit Settings, under the “AI Assistant” tab.
On your computer, open gemini.google.com.
At the bottom left, click “Settings”, then “Connected Apps”. If you don’t see “Connected Apps”, first click “Personal Intelligence”.
In the “Custom apps” section, click “Add a custom app” to create a new custom app.
Paste your Hexfit connection link as the MCP server URL. Leave “Advanced features” empty: Hexfit does not require any authentication.
Click “Next” and follow the on-screen instructions.
In a conversation, type @ and select Hexfit so Gemini uses it. Gemini will ask you to confirm before each creation or change in your account.
That’s it! You can use the same example prompt as above to test it 😁
For advanced users (Gemini CLI): if you use Gemini from the command line, you can also add Hexfit with the following command, replacing the text in quotes with your connection link:
gemini mcp add --transport http hexfit "YOUR_CONNECTION_LINK"
Common issues
I can’t find Hexfit in the list of connectors or apps. That’s normal: Hexfit is not one of the connectors already offered. Create a new custom connector and paste your link into it, as described above.
I get the error “Tool not found”. This usually happens when an existing connector or tool was selected instead of creating a new one. Delete that connector, then create a new custom connector with your Hexfit link and authentication set to “None”.
I get an error about OAuth, a Client ID or a failed registration with the sign-in service. Authentication is not set to “None”. Delete the connector, then create it again choosing “None” as the authentication and leaving the OAuth fields empty.
I’m not an administrator, can I still connect? Yes. Every user finds their own connection link in their Hexfit Settings, under the “AI Assistant” tab.
