Discord MCP Server vs Slack MCP Server

Discord MCP Server and Slack MCP Server are both MCP servers but differ in their categories and capabilities. Discord MCP Server (communication) is The Discord MCP Server (SaseQ/discord-mcp) is a Java-based Model Context Protocol integration built on JDA (Java Discord API) that turns a Discord bot into a set of tools AI assistants can call directly. It lets Claude, Cursor, and other MCP clients read and send channel messages, manage threads, create and moderate channels and categories, manage roles and permissions, look up server (guild) members, and pull message history — enabling AI-driven community moderation, automated announcements, and Discord-native workflows without hand-writing bot code. The recommended install is Docker: set DISCORD_TOKEN (from a bot registered in the Discord Developer Portal) and an optional DISCORD_GUILD_ID as environment variables, then run the saseq/discord-mcp:latest image with SPRING_PROFILES_ACTIVE=http, which exposes the MCP endpoint at http://localhost:8085/mcp for remote/HTTP-transport clients. A Docker Compose path and a stdio-transport mode are also documented for local, per-client setups like Claude Desktop. Because it wraps JDA (Spring Boot underneath), it handles Discord's gateway/rate-limit quirks for you rather than requiring a hand-rolled REST client. This is the most-starred dedicated Discord MCP implementation; other community servers like v-3/discordmcp and hanweg/mcp-discord cover similar ground with lighter Node/Python stacks if a non-JVM runtime is preferred. while 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..

Choose Discord MCP Server if you need communication capabilities and prefer docker installation. Choose Slack MCP Server if you need communication capabilities and prefer npm 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.Discord MCP Server and Slack MCP Servercan complement each other if their capabilities don't overlap.
