Install in ChatGPT developer mode

ChatGPT connects with a sign-in (OAuth), not an API key.

1. Turn on developer mode in ChatGPT’s settings (under Apps / Connectors, Advanced settings). Availability depends on your ChatGPT plan; OpenAI’s developer mode guide has the current path.
2. Create a connector: name Versusbrief, MCP server URL https://versusbrief.com/mcp, authentication OAuth.
3. A Versusbrief page opens. Enter your email and choose Allow.
4. In a chat, pick Versusbrief from the tools and ask: “Build a pitch for theirbusiness.co.uk in Didsbury, GB.”

Billing stays on this website. The chat does not sell a subscription. Developer mode not on your plan? Use Versusbrief on the web with the same email.
