The MCP ecosystem went from a handful of servers to thousands in under a year. Most of them are demos you connect once and forget. A few have quietly become part of how I work every day.
This is the short list that earned a permanent spot in my Claude setup as a solo founder, grouped by what I am actually trying to get done. No affiliate links, no rankings for the sake of it. Just the ones I would reconnect first on a new machine.
The two every setup needs
Filesystem (the official server) lets Claude read and write local files. Boring, essential, and the first thing I connect anywhere.
GitHub brings issues, PRs, and code search into the chat. If you write code, it is the highest-leverage connection after filesystem.
Marketing and growth
This is where MCP stopped being a novelty for me and started saving real hours.
The Google Search Console MCP pulls my live query and impression data into Claude, so I can ask "which pages slipped this week" and get an answer without opening the GSC dashboard.
The Google Analytics MCP server does the same for GA4: sessions, events, and conversions, all queryable in plain English.
If you run sales, the HubSpot MCP server lets Claude read and update contacts, deals, and companies. That turns "draft a follow-up for everyone in the pipeline who went quiet" into a single prompt.
Connecting all three means one question can span search data, analytics, and CRM, and Claude stitches it together. That is the part that still feels like magic.
Automation glue
The n8n MCP server is the one I reach for when a workflow needs to run on a schedule instead of whenever I happen to be in a chat. Weekly digests, smart routing, alerts. n8n already connects to almost everything, and MCP lets Claude drive it.
Knowledge and memory
Claude forgets everything between chats. These servers fix that.
Obsidian and Notion servers expose your notes so Claude can search them and write back.
ContextBolt (full disclosure: I built this one) gives Claude semantic recall over the things I save from X, Reddit, and LinkedIn. I save a thread, and three weeks later I can ask "what was that take on pricing I saved" and get it back with the source. It exists because I kept saving things and never finding them again.
How to pick
Two rules that have served me well:
- Connect for a job, not for a demo. A server you use once is clutter.
- Read the setup notes before you wire up auth. Half of these put a token in a config file or a URL, and the gotchas vary by server.
That second rule is why I keep a running directory of the best MCP servers with per-server setup steps, auth notes, and the gotchas I hit, sorted by category. It started as my own notes. Now it is a public MCP server directory you can browse by job instead of scrolling one giant list.
If you are just getting started, connect filesystem, then add one server for the job in front of you. Build from there.
