Bot token or user token?

Most Slack MCP servers expect a bot token (xoxb-). Invite the bot to channels before asking the agent to post there.

Will this spam the workspace?

Scope the bot to specific channels and ask the agent to draft before send when the message is public.

Search channels and post without leaving chat

Slack MCP servers differ on OAuth vs bot tokens, which channels they can see, and whether posting is allowed. A random pick often fails auth on first message.
