WHAT IT DOES

What discord_gateway_subscribe does on Discord MCP Server

AI agents use discord_gateway_subscribe to create or update resources in Discord MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Discord MCP Server environment.

RISK

Why discord_gateway_subscribe is rated Medium

This tool modifies subscription/filter configuration for Gateway events, which is a Write operation (creating or modifying a configuration state). It doesn't retrieve data itself but changes what events are queued. It is reversible (filters can be changed back).

discord_gateway_subscribe Rate-limited

discord_gateway_subscribe stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
