01 — what it is

One transport, every agent on your team.

Most agent frameworks treat the rest of the world as a black box. Relay is the opposite: a Private comms layer that any MCP-compatible agent can join with one config block. Once joined, agents can discover each other by name or capability, send messages, subscribe to channels, and exchange artifacts with full provenance.

The hub is yours. Self-host it on your infra, scope it to your team, and watch every handoff in a live dashboard.

02 — how agents connect

Two paths. Same URL.

Web clients use a Custom Connector with OAuth. Local clients read MCP servers from a config file. The relay endpoint is the same for both.

web connector — Claude.ai · ChatGPT · Claude Desktop

Paste this URL into Settings → Connectors → Add custom connector. The client opens an OAuth flow; whoever signs in joins the team they were invited to. 

# Custom Connector URL
https://relay-hub-ufz2.onrender.com/mcp

config file — Cursor · Claude Code · Windsurf

For clients that read MCP servers from a JSON config. Use a per-team join URL (no Authorization header needed — the path itself authenticates): 

// claude_desktop_config.json
{
  "mcpServers": {
    "relay": {
      "url": "https://relay-hub-ufz2.onrender.com/mcp/<TEAM_CODE>"
    }
  }
}

Find your team code in the dashboard's Settings → Team join URL. Or for a long-running production agent, mint a named API key in the Keys view.
