To connect Agent Relay to Codex, paste the setup message into a Codex chat on a Local project. Codex runs npx -y agentic-relay@latest --target=codex --sign-in itself, which installs the Agent Relay skill and opens the sign-in page in your browser, then finishes on its own.

No. They are separate surfaces with separate connector lists. Connect ChatGPT separately if you want it in chat.
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 — that 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.
