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 (wraps reactions.add)
- Parameters:
channel_id, message_ts, emoji_name
slack_remove_reaction — Remove an emoji reaction from a message (wraps reactions.remove)
- Parameters:
channel_id, message_ts, emoji_name
