Security and access

Where requests go, whose account Claude uses, and what you control.

Server

mcp.slack.com

On the developer’s own domain (slack.com), not a third-party host. Claude sends requests here when it uses a tool.

Account

Your own Slack account

You sign in when you connect. Claude works through that account, so it reaches what the account can reach.

Control

You approve write tools

In Claude’s connector settings you can choose, tool by tool, whether Claude must ask before using it. Write tools are marked in the list above. See write tools

Policy

Published by Slack and linked from the official listing. Read it ↗

Anthropic’s directory notes that it does not control which tools a developer exposes and cannot guarantee they work as intended or stay the same. Connect connectors you trust.
