What is the Slack Search Function MCP MCP server?

If you want an AI assistant working directly with Slack Search Function MCP, the slack search function mcp mcp server is the bridge. A Model Context Protocol (MCP) server that provides tools and resources to access Slack's search functionality. This server allows LLMs to search and retrieve users, channels, messages, and more from a Slack workspace.

What Slack Search Function MCP does

A Model Context Protocol (MCP) server that provides tools and resources to access Slack's search functionality. This server allows LLMs to search and retrieve users, channels, messages, and more from a Slack workspace.

Tools it exposes

Once connected, the assistant can call these 2 tools directly:

  • Tools — 1. get_users - Get a list of users in the Slack workspace 2. get_channels - Get a list of channels in the Slack workspace 3. get_channel_messages - Get
  • Resources — 1. allusers:// - Get all users in the Slack workspace 2. allchannels:// - Get all channels in the Slack workspace

Installing the slack search function mcp mcp server

Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.

Configuration

Before the server will start you need to supply one environment variable: SLACK_TOKEN. Keep credentials in your client's env block or a secrets manager rather than committing them.

Requirements

  • Bun runtime - Slack API token with appropriate permissions

Where it fits

Communication servers earn their keep on volume — summarising channels and threads that would otherwise cost you an hour of scrollback. Slack Search Function MCP sits in that group, and the shape of its toolset — Tools, Resources — tells you what it is really for. Worth comparing against the other communication servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • It will not start until its required credentials are present, so set those before wondering why the tools never appear.
  • Maintained by takuya0206.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the slack search function mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
