List all text channels in the Discord server.
AI agents call discord_channels to retrieve information from Discord Bridge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about Discord channels without creating, modifying, deleting, or executing any operations. It is purely informational retrieval, fitting the Read category. Severity is low because channel enumeration poses minimal security risk and does not expose sensitive data beyond what a channel member would already know.
From the tool's definition Tool name 'discord_channels' and description 'List all text channels in the Discord server' indicate a read-only operation that retrieves channel metadata with no modifications or side effects.
