Connect ChatGPT

ChatGPT connects to remote MCP servers from its plugins settings in developer mode. This guide connects FloPay MCP and checks that it works. Before you rely on it, see Client support for the latest recorded compatibility runs for ChatGPT.

The ChatGPT menu names below follow OpenAI's guide to connecting ChatGPT. If ChatGPT has changed since, follow that guide and use the FloPay details from this page.

Before you start

• A FloPay merchant operator account. Confirmed actions need the owner or admin role on the merchant.
• A ChatGPT account that can use developer mode. Availability depends on your account and your workspace's policy.
• The FloPay MCP server URL: https://mcp.flopay.com/mcp.

Add FloPay MCP

1. In ChatGPT, open Settings > Security and login and turn on Developer mode.
2. Go to ChatGPT Plugins and select the plus button.
3. Enter a name, such as FloPay, and a short description.
4. Under Connection, enter https://mcp.flopay.com/mcp as the MCP server URL, including the /mcp path.
5. Create the connection.

Sign in and approve

When ChatGPT asks you to authenticate, it opens FloPay's sign-in page:

1. Sign in with your FloPay account.
2. Review the access ChatGPT is asking for. It should include mcp:read, and mcp:write if you want confirmed actions.
3. Choose the merchant ChatGPT works for, and approve.

Check the connection

1. Start a new conversation with the FloPay connection available.
2. Ask: "Search the FloPay developer documentation for how FloPay MCP sign-in works, and give me the source link." ChatGPT should answer from a FloPay knowledge resource and include a source link to a FloPay page.
3. Ask: "Use FloPay to show my company details." ChatGPT should call Company_get. Check that the merchant slug and currency match the merchant you approved.

If ChatGPT finds no FloPay tools, the sign-in did not grant mcp:read. Remove the connection, add it again, and check the requested access. When FloPay publishes a new tool reference, open the connection in ChatGPT Plugins, select Refresh, and start a new conversation. Limits and errors explains any other error ChatGPT reports.

Confirmed actions

FloPay only offers mutating tools to a client that declares it can show confirmation forms, and Client support records whether ChatGPT passed the confirmed action checks. When ChatGPT does show a FloPay confirmation:

• Read the preview before you accept: it lists each change with its values before and after.
• If the form asks for an idempotency key, enter a new unique value, and reuse that value only to retry the same action.
• Decline anything you did not ask for. A declined action never reaches your FloPay account.

Confirmed actions explains previews, expiry, and retries in full.

Disconnect

Remove the FloPay connection from ChatGPT Plugins. ChatGPT stops using FloPay straight away, and any FloPay access token it already holds expires within about 15 minutes.

For a client other than Claude.ai, ChatGPT, or Grok, follow Connect any MCP client.
