WHAT IT DOES

What realtime_management does on Supabase MCP Server - Self-Hosted Edition

AI agents invoke realtime_management to trigger actions in Supabase MCP Server - Self-Hosted Edition. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why realtime_management is rated High

Realtime management implies creating/managing channels, sending broadcasts, controlling presence, and configuring security — these are active operations that trigger external effects (pushing messages to subscribers, changing channel configurations, altering security controls).

RECOMMENDED RULE

The rule that runs realtime_management safely

realtime_management Rate-limited

realtime_management stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
