What is the Slack MCP Server?
Transform your team communication into an AI-powered workflow with Slack, the world's leading workplace messaging platform. Your agent becomes a direct participant in your Slack workspace — sending messages, searching across channels, and reacting to conversations without you ever switching tabs.
What you can do
- Send Messages — Post messages to any channel or DM, including threaded replies, using Slack's rich mrkdwn formatting.
- Search Conversations — Find messages across your entire workspace by keyword, sender, or channel using powerful search modifiers.
- Browse Channels — List all available channels with their topics, purposes, and member counts to understand your workspace structure.
- Read Channel History — Retrieve recent messages from any channel to catch up on conversations or audit activity.
- Manage Users — List workspace members with their roles, emails, statuses, and timezones.
- React to Messages — Add emoji reactions to specific messages for quick acknowledgments.
How it works
- Subscribe to this server
- Enter your Slack Bot Token (from api.slack.com/apps → OAuth & Permissions)
- Start managing your Slack workspace from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Team Leads — broadcast updates, search for past decisions, and monitor channel activity without leaving your AI workflow.
- Developers — get notified, post deployment updates, and search for error reports across your engineering channels.
- Operations Managers — audit communication patterns, find specific discussions, and coordinate across multiple channels effortlessly.

Frequently asked questions
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.
How does Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
