}Security notes
- The local server runs with your user's permissions (the command starts it on your machine). The package is pinned to @latest, so each start can pull a new version; pin a version if you want to review updates.
- Messages it reads can carry prompt-injection instructions, and it can send as you. Keep approval prompts on for sending.
- Community code: read it (or at least the tools it registers) before you give it credentials.

FAQ
What does the Slack MCP Server (community) do?+
Slack channels, DMs, threads and search, with stealth and OAuth modes.
Is the Slack (community) MCP server official?+
Community-maintained (korotovsky on GitHub), not by the company whose product it connects to.
How do I add Slack (community) to Claude Code?+
Run: claude mcp add slack-community -- npx -y slack-mcp-server@latest --transport stdio. Add --scope project to share it with your team through .mcp.json.
How do I use the Slack (community) MCP server in Cursor or VS Code?+
Open the Cursor or VS Code tab above: it has the mcp.json entry and a one-click install link. Cursor uses the "mcpServers" key; VS Code uses "servers" and needs a type ("stdio").
Does Slack (community) work in ChatGPT and claude.ai?+
No: it runs locally over stdio, and ChatGPT and claude.ai only connect to remote servers. Use it in Claude Desktop, Claude Code, Cursor, VS Code or another client that can start a local process.
What are the alternatives to the Slack (community) MCP server?+
Other messaging & email MCP servers: Slack, X (Twitter), Resend, Twilio and Mailgun.
