At a glance.
A compact read before the deeper capability notes and official setup links.

Core features.
Feature cards focus on what the tool helps users do, not generated setup commands.
Model Context Protocol (MCP) server for Slack Workspaces.
This feature-rich Slack MCP Server has:
Search Messages: Search messages in channels, threads, and DMs using various filters like date, user, and content.
Safe Message Posting: The conversationsaddmessage tool is disabled by default for safety.
Stdio/SSE/HTTP Transports & Proxy Support: Use the server with any MCP client that supports Stdio, SSE or HTTP transports, and configure it to route outgoing requests through a proxy if needed.
To enable, set the SLACKMCPADDMESSAGETOOL environment variable.
Search messages in a public channel, private channel, or direct message (DM, or IM) conversation using filters.
All filters are optional, if not provided then searchquery is required.

Agent / Skill / MCP / Workflow fit.
This panel keeps technical format separate from the user-facing AI category.
05
Official setup path.
Generated install snippets are intentionally not mirrored here because they drift. The page links to source-owned setup docs instead.
