MCP is the connector from your AI to the tools you want it to use. It's what makes an assistant like Claude or ChatGPT genuinely powerful, because it lets the AI actually do things in those tools, instead of you copying data back and forth.
If you sell or build online, these are the five I'd connect first. Pick the one that helps with the next thing you need to do.
Commas
If you sell coaching, a course, a paid community, or anything online, connect Commas. Then ask your AI what's selling, who's subscribed, or to create a payment link for a new offer.
Granola
Granola connects your AI to your meeting notes. After a client call, ask it to pull out what they asked for and draft the summary, the next steps for your team, and a proposal, since the details are already there.
Supabase
If you're building an app or a client portal, Supabase gives your AI a way to set up and work with its data: client details, bookings, saved work, the things your app needs to keep after someone closes the page.
Canva
Turn a client proposal into an editable slide deck, then tweak a slide. Or make the posts you need to sell your new offer.
Apify
Pull public posts, prices, or reviews from lots of pages. It can even pull public data from TikTok and Instagram to spot trending content, which you can feed into an AI social-media-manager workflow for your brand.
The connector is what lets the AI execute. Start with the tool that touches the next job on your list, connect it, and ask the AI to do one real thing. Reports pull from your account, so revenue is not profit, and keep your API keys private.
Firecrawl is a solid alternative to Apify for turning websites into research, and Vercel is a good follow-up for putting an app online, but these five cover the most ground without overlapping.
