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.
