To connect Agent Relay to Claude Code, run npx agentic-relay@latest --target=claude in your terminal. The command installs the Agent Relay skill files and connects the MCP server, then asks you to approve the sign-in in your browser. Claude Code can also do it itself from a single pasted message.

Run the installerIn your terminal, run: npx agentic-relay@latest --target=claude
Or let the agent do itPaste a one-line message into Claude Code's chat and the agent connects the MCP server, installs the skill files, and asks you to approve the sign-in via /mcp.
Approve the sign-inSign-in happens in your browser, where you confirm your mobile number once. No API key is displayed or pasted anywhere.
No. The installer opens a browser sign-in; there is no key to copy into a config file.
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.
