MCP (Model Context Protocol) servers connect Claude Code to external tools. I run 13 of them. Here's what each one does and why.
What Are MCP Servers?
MCP servers give Claude Code direct access to external services — GitHub, browsers, databases, search engines — through a standardized protocol. Instead of copy-pasting API responses, Claude can interact with these services directly.
My 13 MCP Servers
1. GitHub MCP
Purpose: Full GitHub integration — create PRs, manage issues, search code, review diffs
Why: Eliminates the git CLI for 90% of operations. Claude can autonomously create branches, commit, push, and open PRs.
2. Playwright MCP
Purpose: Browser automation — navigate, click, type, screenshot
Why: Login to any web service, test UI changes, automate web workflows. I use it for posting content to Medium, LinkedIn, Pinterest, and Quora.
3. Brave Search MCP
Purpose: Web search with structured results
Why: Real-time information Claude's training data doesn't have. Market research, competitor analysis, fact-checking.
4. Context7 MCP
Purpose: Query documentation for any library
Why: Ensures Claude writes code using the ACTUAL API, not hallucinated methods from training data. Critical for accuracy.
5. Stripe MCP
Purpose: Full Stripe integration — products, prices, customers, subscriptions
Why: Manage revenue stack directly. Create products, check balances, handle refunds without leaving the terminal.
6. Memory MCP (Knowledge Graph)
Purpose: Persistent entity/relationship storage
Why: Remember connections between concepts, people, projects across sessions. Claude builds a knowledge graph that grows over time.
7. SQLite MCP
Purpose: Database operations
Why: Store structured data, run queries, build dashboards — all from conversation.
8. Filesystem MCP
Purpose: Enhanced file operations
Why: Directory trees, bulk file operations, file info beyond what basic read/write provides.
9. Sequential Thinking MCP
Purpose: Structured multi-step reasoning
Why: Forces Claude to think through complex decisions step-by-step. Better architecture decisions, fewer bugs.
10. Fetch MCP
Purpose: HTTP requests — fetch URLs, APIs, YouTube transcripts
Why: Grab content from any URL. Useful for research, API testing, and content gathering.
11. Exa MCP
Purpose: Neural search — finds semantically related content
Why: Better than keyword search for research. Finds relevant articles, code examples, and documentation by meaning.
12. Business Hub MCP (Custom)
Purpose: Unified business metrics — Gumroad sales, Mercury balance, Stripe status, site health
Why: One command for complete business overview. Custom-built for my specific stack.
13. Jacob Hub MCP (Custom)
Purpose: Session intelligence, pattern extraction, project management
Why: Tracks work across sessions, finds similar past problems, manages multi-project state.
How to Set Up MCP Servers
In your ~/.claude/settings.json:
{
"mcpServers": {
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "your-token"
}
},
"brave-search": {
"command": "npx",
"args": ["-y", "@anthropic/brave-search-mcp"],
"env": {
"BRAVE_API_KEY": "your-key"
}
},
"playwright": {
"command": "npx",
"args": ["@playwright/mcp@latest"]
}
}
}
The Productivity Impact
| MCP Server | Tasks Automated | Time Saved/Week |
|---|---|---|
| GitHub | PR creation, code review | 3 hrs |
| Playwright | Web automation, testing | 5 hrs |
| Brave Search | Research, fact-checking | 2 hrs |
| Context7 | Doc lookup | 1 hr |
| Stripe | Revenue management | 1 hr |
| Business Hub | Reporting | 2 hrs |
| Total | 14 hrs/week |
Advanced: Building Custom MCP Servers
# Minimal MCP server structure
from mcp import Server
import json
server = Server("my-custom-server")
@server.tool("check_metrics")
async def check_metrics():
# Your custom business logic
return {"revenue": 15000, "customers": 42, "health": "good"}
@server.tool("send_notification")
async def send_notification(message: str, channel: str):
# Send to Slack, email, etc.
return {"sent": True}
if __name__ == "__main__":
server.run()
