What is Slack MCP Server - Complete Implementation?

Slack MCP Server is a FastMCP v2 implementation that integrates with the Slack API. It implements 16 features: 4 required (send message, list channels, get channel history, send DM), 4 optional (list users, search messages, upload file, add reaction), 4 bonus Pomodoro timer features, and 4 utilities. It supports full UTF-8 Korean, dual token system, smart file upload, and async asyncio processing.

How to use Slack MCP Server - Complete Implementation?

Install via uv package manager: clone the repo, run uv venv and uv sync, then create a .env file with SLACK_BOT_TOKEN (required) and optionally SLACK_USER_TOKEN and SLACK_TEST_CHANNEL_ID. Configure a Slack app with required Bot Token scopes (e.g. channels:read, chat:write) and optional User Token scopes. Start the server with python slack_mcp_server.py or uv run slack_mcp_server.py. Invoke tools (e.g. send_slack_message) through any MCP host such as Claude.

Key features of Slack MCP Server - Complete Implementation

  • Full UTF‑8 Korean support in all messages
  • Dual token system: Bot Token + User Token for all features
  • Smart file upload with size‑based optimization
  • Pomodoro timer with automatic notifications
  • Async high‑performance asyncio implementation
  • Detailed error handling for all API calls

常见问题

1

What tokens are required?

A Bot Token (`xoxb‑`) is required for basic operations (message sending, channel listing, etc.). A User Token (`xoxp‑`) is optional but needed for search and large file uploads (>100 MB).

2

What are the file upload limits?

Free plan: 5 GB workspace storage. Individual files up to 1 GB (paid plan). Bot Token can upload up to 100 MB; User Token up to 1 GB.

3

What Slack API rate limits apply?

Rate limits vary by method tier: Tier 1 = 1+ per minute, Tier 2 = 20+ per minute, Tier 3 = 50+ per minute, Tier 4 = 100+ per minute.

4

What scopes must the Slack app have?

Bot Token scopes: `channels:read`, `channels:history`, `chat:write`, `im:read`, `im:write`, `im:history`, `users:read`, `reactions:write`. User Token scopes: `search:read`, `files:write`.

5

How does the smart file upload work?

Small text files (<50 KB) are sent directly as message content; medium files (50 KB–1 MB) as code snippets; standard files (1 MB–100 MB) via standard upload; large files (100 MB–1 GB) require User Token; extremely large files (>1 GB) only share file info.
