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.
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.
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).
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.
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.
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`.
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.
