Hey devs,
MCP is the superpower that connects your AI assistant to the real world - GitHub, databases, browsers, Slack, you name it. But the real magic happens when you pick the right servers that are actively maintained, reliable, and solve actual problems.
Here’s a battle-tested lineup, grouped by what they do best. We’ve linked every server we have live in the 1Server marketplace so you can install them instantly.
With the 1server-mcp-engine everything runs through one connection in your Claude/Cursor/VS Code config. Secrets stay encrypted in the vault, tools hot-reload without restarts, and you even get meta-tools like 1server_install_server and 1server_health to manage everything from inside the chat.
Let’s dive in.
🔎 Search & Research
- Tavily MCP Server - AI-optimized web search that returns clean, usable content instead of link spam
- Exa MCP - Semantic search that actually understands meaning
- Context7 - Live documentation so Claude stops hallucinating outdated APIs
- Perplexity (marketplace link coming soon) - Synthesized answers with real reasoning
Pro tip: Start with Tavily + Exa if research is your daily driver.
🕸️ Web Scraping & RAG
- Firecrawl MCP Server - Turns any URL into clean markdown in seconds. The RAG pipeline favorite.
- Apify (marketplace link coming soon) - 3000+ ready-made scrapers for basically any site on earth
- Crawl4AI (marketplace link coming soon) - Free, open-source, 61k GitHub stars, and still going strong
🛠️ Dev Tools (install these first)
- GitHub MCP Server - PRs, issues, code search, reviews. The one most devs install on day one.
- Sentry - Production errors with full stack traces
- Linear MCP Server - Issue tracking without ever leaving Claude
- Vercel MCP - Deploy, debug failed builds, all from chat
🗄️ Databases
- Supabase MCP Server - Postgres through natural language prompts
- MongoDB MCP Server - 40+ tools for Atlas management
- Neo4j (marketplace link coming soon) - Graph queries and knowledge graphs
📝 Productivity
- Notion MCP Server - Docs, wikis, databases - all promptable
- Slack (marketplace link coming soon) - “Summarize what the team discussed about the launch” actually works
- Zapier MCP - Trigger workflows across 6000+ apps from one prompt
💼 Business
- Stripe MCP Server - Payments, subscriptions, refunds
- HubSpot (marketplace link coming soon) - CRM without opening the HubSpot UI
🎨 Design
- Figma MCP Server - Reads design tokens, inspects components. The design-to-code gap just got a lot smaller.
Quick reality check: You don’t need all of these. Start with 3–5 that solve your actual problems right now. Each server eats into your context window, so quality over quantity wins every time.
How to get all this running in minutes
- Create a free 1 Server account
- Browse the marketplace and hit Install on anything above
- Generate an API key from your dashboard
- Add one block to your MCP client config (full per-client instructions here: 1server.ai/setup):
{
"mcpServers": {
"1server": {
"command": "npx",
"args": ["-y", "1server-mcp-engine"],
"env": { "ONESERVER_API_KEY": "your-key-here" }
}
}
}
That’s it. Restart once (you’ll never do it again). New servers? Install them with 1server_install_server from inside the chat. Something flaky? 1server_health + 1server_restart_server fixes it instantly.
Your move
Pick the servers that match your workflow, install them through the marketplace, and point your client at the engine. Watch your AI go from helpful to actually dangerous (in the best way).
