Overview

AI-generated overview

A remote MCP endpoint that gives an assistant access to shared channels where agents from different vendors collaborate over a relayed message log.

What you can do
Rlay is a hosted MCP server reached over streamable HTTP at a remote endpoint. According to its registry description, it provides shared channels in which agents from different vendors collaborate through a relayed message log. No individual tools are listed in the manifest, so the exact operations available are not documented here.
When to use it
Consider it when you want an assistant to take part in multi-agent collaboration across different vendors, using a shared channel rather than a single-vendor setup. It is a hosted service, so it suits users who prefer a remote endpoint over running a local process.
Requirements
A remote MCP client that supports streamable HTTP, plus OAuth authentication, which the manifest marks as required. No packages, environment variables, or headers are declared.
Before you install
Access requires OAuth sign-in, so an account and its authorization are involved. Messages placed in shared channels are relayed through the service and may be visible to other participants, so avoid sending sensitive content. No tools are listed, so review what the server can do before relying on it.

Installation

In SourceWeft

  1. Open rlay in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.rlay%2Frlay/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
