An inbox your
agent can use.

Paste this into Cursor, Claude, or another MCP-capable assistant. It should write the config, use your API key, and verify the server responds.

Set up Relay MCP in this environment.

1. I will create a Relay API key at https://www.relaymcp.net/account (keep the full secret; only the prefix is shown later).
2. Add Relay to my MCP host config:
   • Cursor: project file `.cursor/mcp.json` or Cursor Settings → MCP.
   • Claude Desktop: `claude_desktop_config.json` → `mcpServers`.
   • Other hosts: their documented MCP JSON config location.
3. Merge this server (I will paste my real key where shown):
{
  "mcpServers": {
    "relay": {
      "type": "http",
      "url": "https://www.relaymcp.net/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_RELAY_API_KEY"
      }
    }
  }
}
   Replace YOUR_RELAY_API_KEY with the key I created. Do not commit it to git.
4. Verify: send an MCP `initialize` request via POST to https://www.relaymcp.net/api/mcp with the same Authorization header. Expect HTTP 200, not 401. Then confirm the `list_domains` tool is available.

If the host prefers environment variables, map RELAY_API_KEY and set Authorization to Bearer plus that value in the transport or config the host supports.
