List Discord channels the bot can access. Returns channel id, name, and key (if in config).
AI agents call list_channels to retrieve information from Discord Notifications MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about Discord channels without modifying, creating, deleting, or executing any operations. It is a straightforward query operation that gathers information about accessible resources. The minimal severity reflects that exposure of channel metadata poses low risk—channel IDs and names are typically discoverable through normal Discord access patterns.
From the tool's definition Tool name 'list_channels' and description states it 'List Discord channels' and 'Returns channel id, name, and key' — purely informational retrieval with no side effects.
