MCPs for live streams, pub/sub, and push updates
Real-time MCP servers expose subscription, pub/sub, and push-notification primitives so agents react to events as they happen instead of polling. Supabase Realtime, Redis pub/sub, and WebSocket bridges are classic examples. Essential for live dashboards, alerts, and collaborative agents.
Real-time MCPs let agents subscribe to live event streams — database change feeds, pub/sub channels, WebSocket streams, and push notifications. Instead of polling, agents react the moment data changes.
When a Supabase row changes, the corresponding Redis cache key is automatically invalidated to keep your API fresh.
Get a Slack alert whenever a critical Supabase table row is created, updated, or deleted — ideal for audit trails.
Sentry new issues are de-duplicated, enriched with commit info, and routed to the right Slack channel based on project.
Grafana alerts are enriched with runbook links and routed to the correct Slack channel based on severity and team labels.
Webhooks are one-shot HTTP callbacks. Real-time is a persistent subscription — you stay connected and receive every event. Real-time is better for high-frequency streams.
Yes. MCP supports Server-Sent Events (SSE) and streamable HTTP transports specifically for long-lived connections and progress notifications.
Low — typically sub-second. Supabase Realtime, Pusher, and Redis pub/sub all target millisecond-scale latency for live updates.
No. Most database MCPs (Supabase, Postgres via LISTEN/NOTIFY) ship real-time capability built in.
