MCP server for Slack — read/write messages, manage threads, and react to messages.

Install

claude mcp add slack -- npx -y [email protected]

Requires: SLACK_BOT_TOKEN, ENABLED_TOOLGROUPS

Our take

PulseMCP's Slack workspace server from the experimental/ tier of their monorepo — explicitly not graduated to their productionized set. It covers a practical read/write surface: list channels, read channels and full threads, post, reply, edit messages, add reactions, and upload text snippets for content exceeding message limits, with an ENABLED_TOOLGROUPS env var to trim the tool surface. TypeScript over stdio via npx, MIT, authenticated with a Slack bot token you provision yourself with seven documented scopes — so access is bounded by the bot's workspace permissions, not a third-party service. Very early (package at v0.0.7, ~170 npm downloads/week) in a crowded category of Slack MCP servers, though the monorepo is actively maintained (72 stars, pushes through July 2026). For teams who prefer a self-provisioned bot token over hosted Slack bridges and can tolerate experimental-tier maturity.
