2. GitHub

Manage repos, issues, PRs, and code reviews.

3. PostgreSQL

Query databases directly.

4. Puppeteer

Browser automation.

5. @buywhere/mcp-server

Commerce API for AI agents. Search products, compare prices, get deals, and fetch recommendations.

6. Docker

Manage containers and images.

7. Brave Search

Web search with AI-friendly results.

8. Memory

Persistent knowledge graph for your agent.

9. Slack

10. Stripe

Payment processing and billing.


Why This List?

I built and tested dozens of MCP servers. The useful ones share three traits: they do one thing well, they are maintained, and they solve real problems.
