Connection problems
The trenz.ai page doesn't open when I connect
Check that your browser doesn't block pop-ups for the assistant. In Claude Code run /mcp and choose Authenticate; in the Codex app click Authenticate next to trenz in the MCPs list; in Codex CLI run codex mcp login trenz.
I clicked Allow but the assistant still shows "not connected"
Close the trenz.ai tab, go back to the assistant and connect again. Make sure you are signed in to the trenz.ai account you want to use.
I connected the wrong trenz.ai account
Sign out of trenz.ai in your browser, sign in with the right account, then remove and add Trenz again in the assistant.
The URL is rejected
Use exactly https://mcp.trenz.ai/mcp/oauth, including /mcp/oauth. Trenz doesn't use API keys, so leave any API key or header fields empty.
ChatGPT doesn't show "Add custom MCP server"
Your ChatGPT plan may not support custom MCP servers, or your workspace admin hasn't allowed it. See Connect ChatGPT.

FAQ
Does it cost extra?
No. Trenz MCP is part of your plan. AI generation uses credits at the same price as on the website.
Can the assistant see my password or payment details?
No. The assistant gets access only through the authorization you approve, and you can revoke it any time in Manage connected apps.
Do my team members need their own connection?
Yes. Each person connects with their own trenz.ai account. On Scale, the 7-day allowance is shared by the team.
Which countries does the data cover?
The same markets as the Discover pages on trenz.ai.
