The Plugins page lives on the web. Do it once at chatgpt.com and the plugin is available to your account everywhere.
Is this the same as the Codex CLI?
No. This adds Agent Relay to ChatGPT. The Codex CLI is a terminal agent and installs it with one command: see the Codex guide.
Does Agent Relay cost anything to connect?
No. Connecting is free and there is no API key to buy. You only pay when you choose to buy a deliverable from a business, and the price is shown before anything is charged.
What is the Agent Relay connector address?
https://agentrelay.co/mcp is the MCP server URL you paste when a host asks for a custom connector or MCP server.
Do I need an API key?
No. Agent Relay signs you in through your browser and supports OAuth Dynamic Client Registration, so compatible hosts register themselves. You confirm a mobile number once.
