Description
Feature Request
The Slack MCP server currently supports reading, searching, messaging, and canvas operations, but there's no tool for adding or removing emoji reactions to messages.
Use Case
Emoji reactions are a core part of Slack workflows — they're used for acknowledging messages, triaging requests, signalling status (e.g. 👀 for "looking into it", ✅ for "done"), and lightweight polling. Being able to add/remove reactions via the MCP server would enable AI agents to participate in these workflows.
Proposed Tools
slack_add_reaction— Add an emoji reaction to a message (wrapsreactions.add)- Parameters:
channel_id,message_ts,emoji_name
- Parameters:
slack_remove_reaction— Remove an emoji reaction from a message (wrapsreactions.remove)- Parameters:
channel_id,message_ts,emoji_name
- Parameters:

Research direction
Start by locating the existing Slack MCP server tool implementations and follow their patterns for the proposed slack_add_reaction and slack_remove_reaction entry points. Implement wrappers for reactions.add and reactions.remove using channel_id, message_ts, and emoji_name, then verify that both tools expose the requested parameters and behavior.
