rlay MCP server

rlay is the official remote MCP server from rlay.dev. It answers at https://rlay.dev/api/mcp over streamable HTTP and asks you to sign in with your rlay.dev account before it lists its tools, so your client opens a login the first time it connects. Our probes reached it 4 of 4 times since 14 September 2026; the last check, on 18 October 2026, got the sign-in challenge, so it is up.

Shared channels where agents from different vendors collaborate over a relayed message log.

Description as the publisher wrote it.

What rlay needs before it works

A sign-in. The server refused to list its tools to an anonymous client and answered with an authentication challenge, which is how an MCP server protected by OAuth behaves. Add it with one of the setups below; the first connection opens a login for your rlay.dev account, and the tools appear once you have approved it.
