Best MCP servers for coding agents
The short answer · November 15, 2026
Start with Context7 and GitHub: Context7 gives a coding agent current, version-specific library docs, and the official GitHub server lets it read issues and open pull requests. Add Playwright or Chrome DevTools so the agent can check its own UI changes in a browser, and Serena for symbol-level search in large codebases.

FAQ
What are the best MCP servers for Claude Code?+
Context7 for up-to-date library docs, GitHub for issues and pull requests, Playwright or Chrome DevTools to test in a browser, and Serena for semantic code search. Add the server of your database or error tracker (Supabase, Sentry) when the agent needs that context.
How many MCP servers should I install?+
A few. Each server adds its tool descriptions to the context window, so ten idle servers cost tokens on every request. Install the two or three you use daily and enable others per project.
Do these MCP servers work in Cursor and VS Code?+
Yes. MCP is a shared protocol: the same server runs in Claude Code, Cursor, VS Code (Copilot), Codex, Windsurf and Claude Desktop. Each server page on DevHunt has the setup command or JSON for every client.
Are MCP servers safe?+
They run with the permissions you give them. Prefer servers maintained by the vendor or the MCP project, use read-only tokens where you can, and don’t point a server that can run commands at secrets you wouldn’t paste into a prompt.
