Does it support file uploads through Claude?

Yes, the server supports file uploads, but for security reasons, all file upload requests are gated behind a mandatory human approval workflow.

What credentials do I need to set this up?

You will need a Slack Bot User OAuth Token (starting with xoxb-) and optionally an App Token if using Socket Mode, configured as environment variables.

Can Claude read all of my Slack channels?

Claude can only access channels that the Slack App has been explicitly invited to and for which you have granted specific OAuth scopes.

Is the Slack MCP Server secure for company use?

Yes, it features a robust Human-in-the-Loop (HITL) system that requires manual approval for sensitive actions like file uploads, bulk messaging, and external channel communication.

How does the approval workflow work?

When Claude attempts a sensitive action, the server creates a request in a local directory. You review the request and approve or reject it before the Slack API call is executed.

Connects Claude Code to Slack for seamless team communication, workspace search, and workflow automation with human-in-the-loop security.

The Slack MCP Server is a Model Context Protocol extension that enables Claude Code to function as an integrated team member within your Slack workspace. It allows Claude to send messages, manage complex threads, upload files, and search across channels while maintaining strict security through a Human-in-the-Loop (HITL) approval system. This skill is particularly useful for developers who want to automate status updates, retrieve team context from channel histories, or manage notifications directly from their terminal while ensuring sensitive operations like external messaging remain under human control.
