MCP Servers: How They’ve Made Claude Code a Superpower for Knocking Out Tech Debt
If you’re drowning in tech debt or constantly battling outdated documentation, MCP (Model Context Protocol) servers are about to change everything. These aren’t just incremental improvements – they’re legitimate game-changers for how we work with AI assistants.
Context7: Finally, No More Phantom APIs
You know that frustration when Claude suggests React hooks from three versions ago? Or APIs that straight-up don’t exist? Context7 killed that problem dead.
Just add “use context7” to your prompt. That’s it. Claude fetches real-time, version-specific documentation. No more debugging phantom APIs. No more outdated patterns.
For fast-moving frameworks like Next.js, React, and Tailwind – where APIs change faster than you can ship – this is massive. My debugging time from bad AI suggestions? Down 80%. When you’re knocking out tech debt, every minute counts.
Memory + Obsidian: Context That Sticks
The Memory MCP server gives Claude persistent knowledge. The Obsidian MCP server lets it navigate my notes on the fly.
No more explaining the same constraints repeatedly. Claude remembers project context and pulls from my vault. Like having a junior dev who actually remembers yesterday’s standup.
Docker on WSL: Do It Right
Quick note for WSL users: Docker beats Node.js directly. Every time.
Why?
- Consistent environments across Windows/WSL
- Better isolation
- Easy cleanup when things break
- Seamless Windows/Linux operation
Docker Desktop’s MCP toolkit gives you one-click installs and proper secrets management. Skip the Node module debugging between Windows and WSL.
Next Steps: Sub-Agents Are Here
Anthropic’s multi-agent research shows 90.2% improvement over single agents. Their orchestrator-worker pattern is exactly where I’m headed.
Simple concept, powerful execution: specialized sub-agents coordinated by a lead agent. One handles migrations, another manages APIs, another reviews security. A whole dev team in your terminal.
Combined with these MCP servers? We’re talking about automating entire categories of tech debt.
Bottom Line
These MCP servers transformed Claude Code from helpful assistant to legitimate superpower. Context7 keeps suggestions accurate. Everything runs clean on Docker/WSL.
Still fighting outdated suggestions? You’re working too hard.
Time to ship.
