Top 10 MCP Servers You Should
Connect to Claude Right Now
Claude without MCP is a brilliant mind in an empty room. These 10 servers give it real hands — to read your GitHub, query your database, browse the web, automate tests, and remember everything across sessions.
🌐5,000+
community MCP servers
📅Nov 2024
MCP launched by Anthropic
🤝Universal
OpenAI, Google, Microsoft adopted it
What is MCP — and Why Does It Matter?
Model Context Protocol (MCP) is an open standard created by Anthropic in November 2024. It is a universal interface between AI assistants and external tools. Think of it as a USB-C port for AI — one standard that lets Claude connect to any data source, API, or service.
Before MCP, integrating Claude with GitHub meant writing custom API wrappers. With MCP, you install a server once and Claude gets a native set of tools — to read repos, create PRs, query databases, scrape web pages, and more. OpenAI, Google DeepMind, and Microsoft all adopted MCP in 2025. It is now the universal standard.
How MCP Works (3 Primitives)
📦 Resources
Raw data Claude can read — database records, files, API responses, repo contents
🔧 Tools
Actions Claude can take — create a PR, run a query, send a message, scrape a URL
📝 Prompts
Reusable templates for specific workflows — code review, analysis, report formats
"Most developers use Claude with zero MCP servers. That means they are using maybe 30% of what Claude can actually do."
📋 The 10 Servers We Cover

PostgreSQL MCP
OFFICIAL@modelcontextprotocol/server-postgres
SQL
Schema
Analytics
Talk to your PostgreSQL database in plain English. Ask Claude to analyse your schema, write optimised SQL queries, identify performance bottlenecks, and generate data reports — without touching pgAdmin or writing a single SQL statement yourself.
✓ Natural language → SQL
✓ Schema inspection
✓ Query optimisation suggestions
✓ Data exploration & reporting
claude_desktop_config.json "postgres": {
"command": "npx",
"args": [
"-y",
"@modelcontextprotocol/server-postgres",
"postgresql://user:password@localhost:5432/mydb"
]
}
💬 TRY THIS PROMPT"Show me which users signed up last month but have never made a purchase. Group by signup source and sort by count."
Browser
E2E Testing
Scraping
Gives Claude full browser control using Microsoft's Playwright engine. Instead of taking slow screenshots, it uses the accessibility tree to interact with pages — making it faster, more reliable, and perfect for test automation, web scraping, and UI interaction workflows.
✓ Navigate and click UI elements
✓ Auto-generate E2E tests
✓ Works on Chromium, Firefox, WebKit
✓ Captures interactions as TypeScript

"command": "npx",
"args": ["-y", "@playwright/mcp"]
}
💬 TRY THIS PROMPT"Go to my app at localhost:3000, test the login flow with email 'test@example.com', and write a Playwright test file for it."
🔥
@firecrawl-dev/mcp-server
Web Scraping
Research
Markdown
Firecrawl converts any webpage into clean Markdown that Claude can reason over. It handles JavaScript-rendered pages, anti-bot protections, and sitemaps — making it the go-to MCP for AI research assistants, competitor analysis pipelines, and content aggregation workflows.
✓ Scrape any URL to clean Markdown
✓ Crawl entire websites
✓ Handles JS-rendered content
✓ Bulk URL processing
claude_desktop_config.json "firecrawl": {

📓
@notionhq/notion-mcp-server
Pages
Databases
Search
Claude gets full read/write access to your Notion workspace. It can create pages, update databases, search your knowledge base, and generate reports — bridging your project management and AI workflows without copy-pasting.
✓ Read and create pages
✓ Update database records
✓ Search workspace content
✓ Generate structured documents
claude_desktop_config.json "notion": {
"command": "npx",

Live Docs
API Refs
No Hallucinations
Solves one of the most frustrating problems with AI coding assistants: stale API knowledge. Context7 fetches live, version-specific documentation for any library — React, FastAPI, LangChain, Anthropic SDK — so Claude always writes code against the current API, not a year-old training snapshot.
✓ Real-time documentation fetch
✓ Version-accurate code examples
✓ Eliminates hallucinated parameters
✓ 1,000+ supported libraries
claude_desktop_config.json "context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"]

🧠
@modelcontextprotocol/server-memory
Knowledge Graph
Persistent
Cross-session
Gives Claude a persistent knowledge graph memory that survives across sessions. It stores entities, relationships, and observations — so Claude can remember your project context, coding preferences, team structure, and past decisions without you repeating yourself every session.
✓ Stores entities & relationships
✓ Persists between sessions
✓ Semantic search over memory
✓ Works with any MCP client

No Code
The automation multiplier. Zapier MCP connects Claude to 7,000+ apps — Gmail, Google Calendar, HubSpot, Airtable, Trello, and more — through Zapier's existing zap infrastructure. You define which actions Claude can trigger, and it executes cross-app workflows from a single conversation.
✓ Trigger any Zapier action
✓ 7,000+ app integrations
✓ Remote SSE — no local install
✓ Define allowed actions in Zapier

💡 Pro Tip: Performance Warning
Each MCP server launches a subprocess in Claude Desktop. Running 10 simultaneously will slow down startup and increase memory usage. The sweet spot is 5–6 active servers. Keep the others configured but commented out, and rotate them based on your current task.
# Always active (core stack):
github, filesystem, memory, context7# Activate per task:
postgres ← when doing data work
playwright ← when doing QA / scraping
firecrawl ← when doing research
zapier ← when doing automation
The Bottom Line
MCP is the single most important Claude feature that most developers have not set up yet. The protocol is now universal — adopted by OpenAI, Google, and Microsoft. The ecosystem has 5,000+ servers. The friction of getting started is one config file and one npx command per server.
Start with GitHub + Filesystem + Memory + Context7 — that alone transforms Claude from a chatbot into a genuine development partner that knows your codebase, remembers your preferences, and never hallucinates an API parameter.
