05FAQ

Slack MCP questions

Is there an official Slack MCP server?

Yes. Slack provides a remote MCP server at https://mcp.slack.com/mcp, listed in Claude’s connector directory with the Anthropic verified mark. You sign in with your Slack account in the browser; there is no API key to paste. It exposes 11 tools: 8 read and 3 write.

What is the Slack MCP server URL?

https://mcp.slack.com/mcp. It is a remote MCP server over streamable HTTP, hosted at mcp.slack.com. Paste it into any client that supports remote MCP servers.

How do I add the Slack MCP server to Claude Code?

Run: claude mcp add --transport http slack https://mcp.slack.com/mcp. Then start Claude Code, type /mcp, choose slack and sign in to Slack. Add --scope user to make it available in every project.

How do I use the Slack MCP server in Cursor or VS Code?

In Cursor, add it to ~/.cursor/mcp.json under "mcpServers" as {"slack": {"url": "https://mcp.slack.com/mcp"}}. In VS Code, add it to .vscode/mcp.json under "servers" with "type": "http" and the same URL. Both apps also accept the one-click install links on this page.

Does the Slack MCP server need an API key?

No key to copy. You sign in to your Slack account in the browser when you first connect, and the client acts with that account’s access.

What tools does the Slack MCP server have?

11 tools: slack_send_message, slack_search_public_and_private, slack_search_users, slack_search_channels, slack_search_public, slack_read_channel, slack_read_thread, slack_create_canvas, slack_update_canvas, slack_read_canvas, slack_read_user_profile.

Does Slack work in ChatGPT?

Yes. Slack is in ChatGPT’s plugin directory, published by Slack.

Should I use an official or a community Slack MCP server?

Start with the directory server: it is run by Slack. The 10 community servers are built by third parties; remote ones route your data through their own hosts and local ones usually need an API key.
