Key takeaways
- MCP plugins let non-technical teams connect AI assistants to business tools like Slack, Notion, HubSpot, and Google Workspace

- Check security scores on MCP Marketplace before connecting any plugin to business data
MCP plugins are not just for developers. Any team that uses AI assistants like Claude Desktop can connect them to business tools: CRM systems, project management, communication platforms, document storage, and analytics.
This guide covers the most useful plugins for business teams. For setup instructions, see How to install an MCP server. For Claude Desktop specifically, see How to set up MCP plugins in Claude Desktop.
What can business teams do with MCP plugins?
With the right plugins installed, you can ask your AI assistant to:
- "Summarize the last week of messages in the #sales channel"
- "Find all open deals in HubSpot over $50k"
- "Create a project brief in Notion from this meeting transcript"
- "Pull the latest revenue numbers from our analytics dashboard"
- "Draft a follow-up email based on yesterday's client call"
Instead of switching between apps, copying data, and formatting it yourself, the AI handles the integration work.

How do you get started?
If your team is new to MCP plugins, start with the tools you already use most:
- Pick one communication tool (Slack or Gmail) so the AI can help with messages
- Pick one knowledge tool (Notion or Google Drive) so the AI can reference your documents
- Add more as needed based on where you spend the most time switching between apps
Setup takes about 5 minutes per plugin. Follow the installation guide to get started.
How do you evaluate plugin security for business data?
Before connecting any plugin to tools that contain business data:
- Check the security score on MCP Marketplace. Every listing includes a report explaining what was analyzed.
- Understand the access level. A Slack plugin will have access to your message history. A CRM plugin will see your customer data. Make sure you are comfortable with that scope.
- Use scoped credentials. When a plugin needs an API key, create one with the minimum permissions required. Do not reuse admin tokens.
- Start with read-only. Many plugins support read-only access. Start there and add write permissions only when you need them.
