summary: 'EventTrader documents ONE outbound webhook surface (registered through the MCP register_webhook tool,
  HMAC-SHA256 signed, two event types) and a large inbound real-time surface (WebSocket channels on wss://cymetica.com,
  described by the provider''s own AsyncAPI 3.0.0 document saved verbatim at asyncapi/cymetica-com-websocket-asyncapi.json).
  Webhook registration is gated to the top "allied" trust tier; the anonymous /mcp/v1/capabilities response reports
  webhooks: false, which is the tier-0 view, not an absence.'
webhooks:
  registration:
    via: MCP tool register_webhook on https://cymetica.com/mcp/v1
