Slack MCP Server vs Telegram MCP Server

Slack MCP Server and Telegram MCP Server are both MCP servers but differ in their categories and capabilities. Slack MCP Server (communication) is The Slack MCP server (built by Ivan Korotovsky) connects AI assistants like Claude, Cursor, and Windsurf directly to Slack workspaces, enabling conversational access to your team communication channels without requiring workspace admin approval for a bot install. Its standout feature is a "no permission" stealth mode — it authenticates using your own personal Slack session tokens (xoxc/xoxd, or a stored browser session) rather than requiring a Slack App with OAuth scopes, so it works even in locked-down workspaces where you cannot create bots. It also supports full OAuth Bot Token auth and Enterprise/GovSlack deployments for teams that prefer a conventional app install. Tools exposed include reading channel and DM/group-DM history with smart pagination, searching messages across the workspace, posting messages and thread replies, listing channels and users, and adding reactions. Common use cases include automating standups by posting summaries directly to team channels, searching past Slack conversations to surface decisions or context, monitoring specific channels for keywords or alerts, and drafting replies to thread discussions — all from natural-language prompts. Supports both Stdio and SSE transports plus proxy configuration for corporate networks. Install with: `npx slack-mcp-server@latest --transport stdio`. A separate official-style integration exists from Zencoder (@zencoderai/slack-mcp-server) for teams that prefer standard Bot Token OAuth over session-token auth. Compatible with Claude Desktop, Cursor, VS Code, Windsurf, and Cline. while Telegram MCP Server (communication) is A Telegram MCP server that connects Claude, Cursor, and other MCP-compatible clients directly to a Telegram user account via the Telethon library, exposing 80+ tools grouped into accounts, chats/groups, messages, contacts, media, profile/privacy, and folders/drafts. It supports multi-account setups (list accounts and route tool calls by label), full group and channel administration (create/join/leave, invites, bans, admin roles, slow mode, topics), rich messaging (send, schedule, edit, delete, forward, pin, reply, search, polls, reactions, inline button inspection and press), contact management (add/remove/block/import/export), and media handling (files, voice notes, stickers, GIFs, downloads/uploads). All tool results containing Telegram user-controlled content are sanitized before being returned as structured JSON, and a device-identity feature lets the session appear as a distinct, labeled client rather than a generic script. Authentication uses a Telegram API ID/hash from my.telegram.org plus a generated session string — no bot token required, since this operates as a full user account. A `TELEGRAM_EXPOSED_TOOLS=read-only` mode is available to restrict the MCP surface to read-only tools when write access is not needed. The project explicitly warns against installing the unrelated `telegram-mcp` package from PyPI, which is owned by a different, unaffiliated project — always install from source via `uv sync`..

Choose Slack MCP Server if you need communication capabilities and prefer npm installation. Choose Telegram MCP Server if you need communication capabilities and prefer source installation. Consider your specific use case and integration requirements.

Yes, you can use multiple MCP servers together in Claude Desktop, Cursor, VS Code, and other MCP-compatible clients.Slack MCP Server and Telegram MCP Servercan complement each other if their capabilities don't overlap.
