Communicationby SlackbrokenBot tokenFree with a Slack workspace
01What it is
The Slack MCP server lets your agent read channels and threads, post messages and replies, add reactions, and look up users — so it can participate in the team's conversations, not just observe them.
Who it’s for: Teams who want an agent that can report, notify, and respond directly in Slack.
02Highlights
Read & post
Pull channel and thread history, then post messages and replies where they belong.
React & look up
Add reactions and resolve users and profiles for richer, targeted messages.
03Add it to your agent
Local MCP server — runs on your machine via the command below.
claude mcp add slack -- npx -y @modelcontextprotocol/server-slack
{ "mcpServers": { "slack": { "command": "npx", "args": ["-y","@modelcontextprotocol/server-slack"] } } }
