Slack MCP server
Lets the model read and post to the Slack channels it can access: search history, summarise a thread, or draft a message for you to send.

MCP · Free, open source; needs a Slack app and bot token
Most setups limit this to reading plus drafting and keep posting out, and that default is right. A model that posts to Slack unsupervised can post the wrong thing to the wrong channel just as unsupervised. Most of the real time saving comes from reading and summarising threads anyway.
Notes from the author
Scope the bot token to named channels and avoid a workspace-wide token. A leaked workspace token ruins your week. A leaked channel token ruins a channel.
