eyeball-mocks is a separate nested repository in the current source distribution. Its packages are not claimed as published npm releases.

Bash
pnpm --dir mocks install
pnpm --dir mocks build
pnpm --dir mocks mockhouse

Mockhouse mounts provider-shaped apps under stable prefixes:

Text
http://127.0.0.1:<port>/gmail/...
http://127.0.0.1:<port>/slack/...
http://127.0.0.1:<port>/twilio/...

For focused tests, compose only what you need:

js
import { startMockServer } from "@eyeball-mocks/kit";
import { createGmailMock } from "@eyeball-mocks/email";
import { createSlackMock } from "@eyeball-mocks/messaging";

const server = await startMockServer({
  providers: [createGmailMock(), createSlackMock()],
  port: 0,
});

process.env.EYEBALL_GMAIL_BASE_URL = server.baseUrls.gmail;
process.env.EYEBALL_SLACK_BASE_URL = server.baseUrls.slack;

// Run the normal executor and adapter assertions here.
await server.close();

Use each manifest's declared base-URL variable; there is no aggregate request-controlled provider origin. The /_mock control plane is loopback-only and never called by an adapter.
