Slack
Send messages, create canvases, and fetch Slack data
Connect to Slack to share messages and create canvases directly to simplify collaboration and boost productivity. Search and retrieve messages, channels, threads, files, and users, giving Claude the context to streamline your work.
Want skills and commands too? Slack is also available as a Claude Code plugin.
Install
1Add the server to Claude Code
claude mcp add --transport http slack https://mcp.slack.com/mcp2Sign in
Run /mcp in Claude Code and complete the login flow for this server.
These instructions target Claude Code. Check the publisher's documentation for support in other Claude surfaces; a valid server URL alone does not establish compatibility.
JSON.mcp.json for a shared project
Commit this file so everyone on the project gets the same server.
