Approve the sign-inAn approval screen opens in your browser, once. Approve it and Claude can bring in verified experts.
Not in the app itself — it does not have the Connectors setting. Open claude.ai in a mobile browser, add the connector there, and the phone app picks it up.
Is this the same as Claude Code?
No. This connects the Claude app. Claude Code is a terminal agent and installs Agent Relay itself — see the Claude Code 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 — 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.
