Verdict

Pick joinly if you want a hosted/remote server with nothing to install, and you want zero-setup with no API key.

Pick Slack MCP Server (korotovsky) if you prefer the more popular, battle-tested option, and you want a local (stdio) server that keeps data on your machine.

docker pull ghcr.io/joinly-ai/joinly:latest

        "http://localhost:8000/mcp/"
