README

slackxmcp

slackxmcp is an open-source Slack stdio MCP server built on top of the official @slack/bolt, @slack/web-api, commander, and @modelcontextprotocol/sdk.

It lets MCP-compatible clients interact with Slack through Web API tools and optionally subscribe to inbound Slack messages through a Socket Mode powered MCP notification channel.

Highlights

Exposes Slack as an MCP server over stdio.
Uses Slack Bolt Socket Mode for inbound event delivery.
Uses the official Slack Web API client for reads and writes.
Supports interactive configuration via slackxmcp configure.
Provides tools for identity, status, conversation lookups, history, thread replies, and common message mutations.
Can emit incoming Slack message events over an optional MCP notification channel.

Requirements

Node.js 24+
A Slack app with Socket Mode enabled

Slack App Setup

At minimum, configure:

Socket Mode enabled with an app token that has connections:write
Token scopes for whichever Slack token you use:
- channels:read
- groups:read
- im:read
- mpim:read
- channels:history
- groups:history
- im:history
- mpim:history
- chat:write
- reactions:write
- users:read
Event subscriptions for the message surfaces you care about, such as:
- message.channels
- message.groups
- message.im
- message.mpim

Depending on your workspace policy and the conversations you target, Slack may require additional scopes.

If you want to use slack_search_messages, you will typically also need a user token with search:read because Slack does not expose message search through bot tokens.

Installation

Use it without installing globally:

npx slackxmcp mcp

Or for local development:

npm install
npm run build
npm run dev -- mcp

Quick Start

Run the interactive configuration:

slackxmcp configure

This writes:

~/.slackxmcp/config.json

Start the MCP server:

npx slackxmcp mcp

If your MCP host supports notifications and you want inbound Slack events, enable channels:

npx slackxmcp mcp --channels

The server uses stdio, so it is meant to be launched by an MCP client or wrapper rather than browsed directly in a terminal.

CLI Usage

MCP Server

npx slackxmcp mcp

Starts the stdio MCP server for the configured Slack app.

Configure

npx slackxmcp configure

Then opens an interactive configure UI (Ink) to manage:

App token
Bot token
User token
Allowed users
Allowed channels

Allowlist items are toggled from menu screens (select an entry to toggle it, then choose Back).

Allowed users/channels screens support live type-to-filter search with a 5-row scroll viewport for faster selection in large workspaces.

Everything is persisted to:

~/.slackxmcp/config.json

MCP Tools

The server currently exposes these tools:

slack_get_me
slack_get_status
slack_get_channel
slack_get_channel_members
slack_list_channels
slack_list_users
slack_search_messages
slack_get_channel_history
slack_get_thread_replies
slack_send_message
slack_send_files
slack_reply_to_message
slack_react_to_message
slack_edit_message
slack_delete_message

Push Channel

When started with --channels, the server:

advertises the experimental MCP capability hooman/channel
advertises hooman/user with path meta.user
advertises hooman/session with path meta.session
advertises hooman/thread with path meta.thread
advertises hooman/channel/permission for remote daemon approvals
emits notifications/hooman/channel for inbound Slack message events

If allowlist entries are configured, notifications/hooman/channel events are emitted only when either:

meta.session (conversation ID)
