ChatGPT supports remote MCP servers through its Connectors feature, which means you can add Brivvy without editing any config files. Once connected, ChatGPT can call Brivvy tools mid-conversation to retrieve brand voice guidelines and list templates.
Brivvy’s MCP server uses tools beyond the default search and fetch pattern, so Developer Mode must be enabled for the integration to work. Without it, ChatGPT will reject the connection.
MCP connectors and Developer Mode require a ChatGPT Pro, Plus, Business, Enterprise or Edu plan.
Before you start
- A Brivvy account on a plan that includes MCP access.
- A ChatGPT Pro, Plus, Business, Enterprise or Edu account.
- For team workspaces: admin access to enable Developer Mode at the workspace level.
Setup
Before your team can use Developer Mode, a workspace admin must enable it. This allows members to create custom MCP connectors.
- In ChatGPT, click your workspace name in the top left and select Admin panel.
- Navigate to Permissions & Roles in the sidebar.
- Under Connected Data, enable Developer mode / Create custom MCP connectors.
- Members in your workspace can now enable Developer Mode in their own settings and add MCP connectors.
Once your workspace admin has enabled Developer Mode (or if you are on an individual Pro or Plus plan), follow these steps to connect Brivvy.
-
In ChatGPT, click your profile picture in the top right and go to Settings > Apps > Advanced settings. Toggle on Developer Mode.
-
Go to Settings > Connectors and click Create.
-
Fill in the connector details:
| Field | Value |
|---|
| Connector name | Brivvy |
| Description | Access Brivvy brand voice rules and templates |
| MCP server URL | https://mcp.brivvy.io |
-
Make sure Authentication is set to OAuth and click Create.
-
ChatGPT will open an authorization page. Review the requested permissions and click Authorize to grant ChatGPT access to Brivvy on your behalf.
-
Start a new chat, click the tools menu near the message input and select Developer Mode. Choose Brivvy from the list. The connector stays active for the entire conversation once enabled.
How to know it worked
Send a prompt that requires brand voice context, for example: “Using Brivvy, get the brand voice rules and write a two-sentence product update.” ChatGPT will call the appropriate Brivvy tool and return a response shaped by your brand voice rules. Tool-call payloads are displayed in the UI as ChatGPT works, showing inputs and outputs for each Brivvy tool called.
