WHAT IT DOES

What add_multiple_reactions does on Discord MCP Server

AI agents use add_multiple_reactions 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.

WHY IT NEEDS A POLICY

Why add_multiple_reactions needs a policy

Adding reactions to messages modifies Discord message metadata in a non-destructive, reversible manner. While it changes state, it does not delete data, execute arbitrary code, move money, or cause irreversible damage. The blast radius is minimal—at worst, unwanted emoji reactions appear temporarily on messages, which can be undone.

From the tool's definition Tool name 'add_multiple_reactions' and description 'Add multiple reactions to a message' indicate a modification operation that adds emoji reactions to existing messages. This is a reversible action (reactions can be removed).
