FAQ from Slack MCP Server

What OAuth scopes are required?

Essential scopes are channels:read, channels:history, groups:read, groups:history, users:read, users:read.email, and team:read. Additional scopes for full functionality include im:read, im:history, mpim:read, mpim:history, search:read, files:read, reactions:read, reactions:write, and bookmarks:read.

How to fix "channel_not_found" error?

Ensure the bot is a member of the channel, use the channel ID (not the name), and verify the channel has not been archived.

How to fix "missing_scope" error?

Add the required OAuth scopes to your Slack app and reinstall the app to your workspace. Some scopes may require admin approval.

Why are no messages returned?

Verify the bot has the appropriate history scope for the channel type (public, private, DM). Check the time range parameters and ensure the channel contains messages in that range.
