How do I get started with Slack MCP?

Subscribe, then create a Slack App at **api.slack.com/apps → Create New App**. Go to **OAuth & Permissions**, add the required bot scopes (channels:read, chat:write, search:read, users:read), install the app to your workspace, and paste the **Bot User OAuth Token** (starts with xoxb-) here. No code, no webhooks — just connect and go.

Can my AI agent send messages and reply in threads?

Yes. Your agent can post to any channel the bot has been invited to — including threaded replies. Just say 'post in #engineering that the deploy is complete' or 'reply in the thread about the bug fix'. It supports Slack's full mrkdwn formatting including bold, links, code blocks, and mentions.

How can I find a specific conversation from last week?

Tell your agent to search for it — 'find messages about the Q3 budget review' or 'search for messages from @sarah about the client proposal'. The agent uses Slack's search API with support for modifiers like from:user, in:channel, and date ranges. No more scrolling through channels — your agent retrieves the exact messages you need.

Can I manage multiple channels and monitor team activity?

Absolutely. List all channels to get an overview of your workspace structure, read history from specific channels to audit conversations, and check team member profiles, statuses, and timezones. Perfect for distributed teams, engineering organizations, and operations managers who need a bird's-eye view of communication across dozens of channels.
