Best MCP Servers for Claude Code: 16 MCPs to Transform your Work
Use these MCPs to do research, sell, build, publish, debug. Without breaking your chain of thought.
Most people use Claude Code with zero MCPs. Here’s what happens when you connect it to Perplexity, NotebookLM, Stripe, Gumroad, Notion, and everything else: research, payments, scheduling, publishing, all without breaking your chain of thought. Real workflows, one-line installs, and the story behind the protocol.
The one rabbit hole I have gone deep into over the past year, it’s MCP.
I’m an AI builder and vibe coder whose attention is spread across everything: writing articles, creating products, managing a community, selling on Gumroad, researching, coding, publishing across platforms. All of it, every day.
Every time I hit friction in any of those workflows, the answer kept being the same: there’s an MCP server for that.
So when I say “best MCP servers,” I don’t mean the ones with the most GitHub stars. I mean the ones that survived daily use across all of this. I tried dozens. Dropped most. Kept a handful. The same filtering logic applies to Claude Code plugins: I went through 10 and most aren't worth the install.

Hi, I’m Jenny 👋
I build AI systems and tools, then share how I did it. I run the Practical AI Builder program — for people who already use AI and want to build real things with it. Check it out if that sounds like you.

How MCP Became the Standard for AI Tools (And Why It Matters)
Before I walk you through the stack, let’s talk about what MCP is and why the story behind it matters more than any individual server.
What MCP is (2-minute version)
MCP = Model Context Protocol. It’s how AI tools connect to everything else.
Claude Code without MCP is a phone that only makes calls.
MCP servers are the apps.You don’t need to build these connections yourself. Over 1,000 already exist. You install them.
Without MCP: copy-paste between Claude and everything else.
With MCP: Claude reads your real data, takes actions, remembers across sessions.
If you’re brand new to Claude Code itself, start with the beginner guide first. MCP is what you add after you’re comfortable with the basics.
The origin story — and the massive move
November 2024: Anthropic creates MCP and open-sources it. Free. Open standard. Python and TypeScript SDKs.
Months later: Cursor adds support. Windsurf adds support. Zed, Replit, Codeium, Sourcegraph. One by one, the developer tools start speaking the same protocol.
March 2025: Sam Altman publicly announces OpenAI will adopt MCP across ChatGPT and all products. Their direct competitor’s protocol.
Then: Google follows with Gemini. Microsoft brings it to Copilot.
Then: Anthropic donates MCP to an independent foundation so no single company owns it.
By early 2026: 1,000+ community-built MCP servers.
When your biggest rival looks at what you built and says “we’re using that” — the standard already won. This isn’t “Claude has plugins.” Anthropic wrote the USB spec for AI tools, then gave it away so the whole industry could build on it.
And that has a direct consequence for you:
If an MCP server doesn’t work across tools, it’s incomplete.
The protocol is client-agnostic by design. A properly built server works in Claude Code, Claude Desktop, Cursor, Windsurf, and VS Code. The only thing that changes is one config path:
Same server. Different path. If someone builds an MCP locked to one tool, that’s either intentional decision or sloppy implementation. The whole point is: invest once, use everywhere.
Months ago, I wrote about this mindset change, MCP is essentially turning Claude from a chatbot into a connected intelligence.
Since then I’ve been building and running MCP servers daily.
MCP servers are how you give AI agents real capabilities, connecting them to your tools, data, and workflows.

How to Choose the Right MCP Server for Your Stack
The MCPs worth keeping are the ones that match your friction, not the trending list.
My stack looks weird to a developer, a marketer, a writer. It looks right for someone who runs a newsletter, a community, a Gumroad store, a handful production apps and client projects all at once.
I started with three questions:
What am I copy-pasting?
What tabs do I keep switching between?
Where do I lose 10 minutes every time?
Every MCP I kept exists because it killed a specific friction point. Your stack will look different. That’s the point.
After that, you start stacking up plugins and skills with it.
Memory is the most underrated category.
Most people start with data connectors or research tools. Useful, but incremental.
After interviewing about MemMachine, the open-source AI memory layer his team built at MemVerge, I got fully inspired and extended my own memory layer for Claude. An MCP that I call it ai-memory-agent.
Memory changes the whole relationship. Claude goes from “tool I explain things to every session” to “collaborator who knows my projects, my voice, my decisions.” This is the MCP that makes every other MCP more powerful.
Best MCP Servers for Claude Code: All 16 Ranked by Friction Killed
The MCPs worth keeping are the ones that match your friction, not the trending list. Every server in this list replaced a specific copy-paste habit, a tab I kept open, or a 10-minute task I did manually.
You can find listicles anywhere. Claude Desktop shows dozens in its integrations page.
After going through dozens of servers, I noticed every MCP does one of four things:
connects Claude to your existing data,
helps Claude research without you switching tabs,
gives Claude memory that persists across sessions, or
lets Claude take action on your behalf.
The four categories describe the primary friction each MCP removes. Many MCPs blur across categories. I put each one where it makes the biggest dent in my day. Your categorization might look different, and that’s totally fine.
For each MCP, I’m rating setup difficulty, how often I actually use it, and cost, based on months of daily use.
🟢 Easy (one config line, minutes)
🟡 Medium (API key or auth flow, under an hour)
🔴 Advanced (self-hosting, multiple steps)

#1. Connect: Give Claude a Direct Line to Where Your Stuff Lives
These are the MCPs where the mental leap is the smallest. Of course Claude should be able to see your Notion. Of course it should read your Slack.
The friction they kill: copy-pasting between apps, re-uploading files every session, and logging into services just to check one thing.
- Notion MCP · 🟢 Easy setup (OAuth) · Daily · Free server, Notion plan
claude mcp add --transport http notion https://mcp.notion.com/mcp
Connects to my workspace where I plan shared items: content calendars, project tracking, task databases. Claude pulls what I need without me switching tabs.
The Notion AI agents guide I wrote shows what becomes possible once Claude can see your workspace.
- Slack MCP · 🟢 Easy setup · Daily · Free server, Slack plan
claude mcp add --transport http slack
Reads messages, searches channels, pulls thread context. Replaces the friction of logging into Slack, scrolling to find a conversation, copy-pasting the relevant parts, and explaining the context.
- Google Drive MCP · 🔴 Advanced setup (self-host with Google Cloud OAuth) · Weekly · Free
Google shipped official MCP servers for Maps, BigQuery, and Compute Engine, but not Drive. You’d need to self-host a community server and configure your own OAuth credentials. It works once running, but the setup friction is real compared to Notion and Slack where it’s one command and a browser prompt. Google will get there.
- Supabase MCP · 🟢 Easy setup (built into Claude Code) · Every session · Free server, Supabase plan
claude mcp add --transport http supabase “https://mcp.supabase.com/mcp?project\_ref=YOUR\_REF”
Retrieves my community database, my app data, my builder profiles. Also writes data, runs migrations, deploys edge functions. In my day its primary role is connecting Claude to what’s already in the database.
- Obsidian MCP · 🟡 Medium setup (manual install from GitHub) · Daily · Free
If your knowledge base lives in Obsidian, this connects it. Separate plugins exist for Claude Code and Claude Desktop, no single unified server yet.
#2. Research: Let Claude Look Things Up For You
These MCPs don’t just connect to data you already have; they search, process, and synthesize things you don’t have yet. The mental leap is a little bigger: instead of “Claude can see my files,” it’s “Claude can go find things for me.”
- Perplexity MCP · 🟡 Medium setup (session token) · Every session · Free server, Perplexity subscription
claude mcp add perplexity -e PERPLEXITY_SESSION_TOKEN=”your_token” -- uvx --from “perplexity-webui-scraper[mcp]@latest” perplexity-webui-scraper-mcp
The MCP I reach for most. Web search with multiple AI models, fact-checking, competitive analysis, real-time research. Any time I need to verify a claim or check what’s current, Claude searches and returns results with citations. No browser tab.
To learn more about the power it unlocks, read the deep dive on how Perplexity MCP with Claude in Chrome transforms your search workflow.
- NotebookLM MCP · 🟡 Medium setup (auth required) · Weekly · Free
claude mcp add notebooklm -- uvx notebooklm-mcp
Deep research synthesis. I seed sources into a notebook, competitor articles, research papers, documentation, and Claude queries the synthesized results. Also generates audio overviews, which I use for content research while making dinner.
- Substack Article MCP · 🟡 Medium setup (auth required) · Daily · Free
claude mcp add substack-article -- npx -y substack-article-mcp
This one’s built by me. It reads published articles, checks engagement stats, pulls full text for repurposing. Technically it connects to my newsletter, but the reason I reach for it is research, looking up what I’ve already published, finding internal links, checking what angles I’ve already covered, and finding articles I’m interested in. It’s lookup, not action.
- Whois MCP · 🟢 Easy setup · As needed · Free
claude mcp add whois -- npx -y @bharathvaj/whois-mcp@latest
Domain availability lookups. Admittedly, I buy a lot of domains... quickviralntoes.xyz, substackexplorer.com, vibecoding.builders, postingly.io…
Two seconds per check, no browser needed, cross-compare ten name ideas in real time.
#3. Remember: Give Claude a Brain That Persists
This is where the mental leap gets real:
Data connectors give Claude access to your stuff.
Research lets Claude find new stuff.
Memory gives Claude access to you, your projects, your decisions, your voice, your relationships.
The friction it kills: re-explaining yourself at the start of every session. Both of these are custom-built. I’ll show how they work in reality in the next section.
- AI Memory MCP · 🟡 Medium setup (remote database) · Every session
Custom build — persists memories in a database with semantic search. Store decisions at key moments, retrieve them across sessions.
I built this one. Claude remembers my projects, decisions, preferences, writing voice, deadlines, and action items across sessions. This is the MCP I used the most. Always.
- DuckDB / StackContacts MCP · 🟡 Medium setup (local database) · Weekly
Built by . Local database with contact and subscriber information — Claude knowing my world, not just my files.

#4. Act: Let Claude Ship, Sell, and Publish
Everything above is about Claude understanding and thinking. This is where Claude does things in the real world, on real platforms, to real audiences.
The biggest mental leap: you’re not just giving Claude access. You’re giving it permission.
- Substack Notes MCP · 🟡 Medium setup (API token) · Daily · Free*
claude mcp add -s user substack-notes -- npx -y substack-notes-mcp --token YOUR_TOKEN
Get the installer and token at quickviralnotes.xyz/settings.
Handles my entire notes pipeline. Claude generates notes from articles using formulas I’ve tested, schedules them across days with proper spacing. What used to be a 45-minute manual process is now one sentence and a review pass.
- Gumroad MCP · 🟡 Medium setup (API key) · Weekly · Free server, Gumroad account
claude mcp add gumroad -e GUMROAD_ACCESS_TOKEN=”your_token” -- npx -y gumroad-mcp-server
Create offer codes, check sales data, manage products. When I finish an article that references a product, I create a launch code in the same conversation, no separate login.
- Stripe MCP · 🟢 Easy setup (OAuth) · Weekly · Free server, Stripe account
claude mcp add --transport http stripe
Manage payments, subscriptions, create coupons. Combined with Supabase for the database layer, I can troubleshoot a payment issue end-to-end without opening three dashboards.
- Crosspost MCP · 🟡 Medium setup (API key) · Weekly · Free*
claude mcp add crosspost -e CROSSPOST_API_KEY=”your_key” -e CROSSPOST_API_URL="https://postingly.io" -- npx -y crosspost-mcp
Sign up at postingly.io to get your API key. Posts to X, Bluesky, LinkedIn, and Threads from one conversation. Claude adjusts for each platform’s character limits, formatting, and expectations. One conversation, four platforms.
- n8n MCP · 🔴 Advanced setup (self-hosted) · As needed · Free (self-hosted)
claude mcp add n8n -e N8N_BASE_URL="http://localhost:5678" -e N8N_API_KEY=”your_key” -- npx -y @nicobailon/n8n-mcp-server
Workflow automation, webhook triggers, multi-step sequences, connecting services that don’t have their own MCP. When I need something more complex than a single MCP can handle, n8n fills the gap.
This isn’t the full list. There are 1,000+ MCP servers and counting. I put together a curated directory of 70+ verified servers with install instructions, repo links, and status for every one. Grab the Complete MCP Server Directory for free.

What Real MCP Workflows Look Like: 5 Examples With Prompts
The list above tells you what each MCP is. This section shows how they work together. My week doesn’t split into “data connector time” and “research time.” It splits into writing, publishing, selling, building, and planning. The MCPs blur across all of it.
