Frequently asked questions
Which MCP server is faster to set up, Discord MCP or Slack MCP?
Discord MCP typically installs via a single npm or pip command and asks for Discord bot token. Slack MCP needs Slack bot token. Expect 2-5 minutes for either once credentials are ready. If you already have Discord configured, Discord MCP wins by a minute or two.
Can I run Discord MCP and Slack MCP side by side in the same Claude client?
Yes. Claude Desktop, Cursor, and Claude Code all accept multiple MCP servers in the same config file. Each runs in its own process and exposes a distinct tool namespace, so there are no naming collisions. Memory usage is additive; budget roughly 40-80 MB per server.
How do Discord MCP and Slack MCP compare on cost?
Discord MCP is free, OSS. Slack MCP is free server, Slack plan applies. Most of the real spend is on the underlying service, not the MCP server itself; the server is almost always free. Budget based on query volume at the backend, not the MCP layer.
Is Discord MCP or Slack MCP more production-ready?
Discord MCP is community-maintained, so check recent commits and open issues before relying on it. Slack MCP is backed by Anthropic (reference). For critical workloads, pick the vendor-backed option or pin a specific version.
What authentication does each server need?
Discord MCP authenticates with Discord bot token. Slack MCP uses Slack bot token. Store secrets in a password manager or your shell's keychain and inject them via environment variables; never commit them to the MCP config file, which is often synced across machines.
Which one should I pick first if I am just starting with MCP?
Start with whichever backend you already pay for or use daily. If you do not use either yet, Discord MCP is fully OSS, so there is no signup friction. You can always add the second one later without disrupting the first.
