The relay layer

Connect everything.
Build nothing.

One endpoint fans out to all your services. We carry the traffic. You ship.

No credit card required.

Always PROTECTED

See how origin shield works

  • Your servers, invisible.
    Clients connect to us, never to you. Your real infrastructure stays completely off the map.
  • Flood protection, built in.
    We stand between you and the internet. Threats hit us first. And stop there.
  • Confidential by design.
    We can't read your stored secrets. Your keys, encrypted. Bring your own — we see nothing, keep nothing.
  • Nothing slips through.
    Payloads validated against your schema. Malformed or malicious data stops here.

Built for AI.

Your agent configures EchoRelay. You ship.

One endpoint, the whole control plane.

A single MCP server (Model Context Protocol — how AI agents call tools) exposes your API versions, endpoints, targets, billing.

Drops into any agent.

Claude, ChatGPT, Cursor, OpenCode. Bearer token in, project on rails.

No forms. No clicks.

Describe the integration in plain English. Your agent writes the config.

See the call

Your agent does this:

POST https://mcp.echorelay.dev
{
  "jsonrpc": "2.0", "id": 1,
  "method": "tools/call",
  "params": {
    "name": "create_endpoint",
    "arguments": {
      "lineKey": "v1",
      "endpoint": {
        "name": "Webhook",
        "url": "/notify",
        "httpMethod": "POST",
        "targets": [{
          "name": "Slack",
          "targetUrl": "https://hooks.slack.com/..."
        }]
      }
    }
  }
}

How it works

One call in, fanned out.

You call once. We authenticate, validate, bill, and fan it out — to every service you connect. The same relay works the other way too: point traffic at us and we shield, validate, and ingest it.

See how fan-out works

  1. Caller
    Your app sends one request.
  2. EchoRelay
    Authenticated, validated, billed — then fanned out.
  3. Queue
    Durable queue. At-least-once, always.
  4. Delivery
    Delivered with retries; nothing lost.
  5. Your targets
    Every service you connect.
  • At-least-once delivery
  • Automatic retries
  • Replayable failure queue
