Feature Comparison
| MCP server | Best for Claude Code | Setup priority |
|---|---|---|
| Filesystem | Scoped local project context and file access | First install for local repo work. |
| GitHub | Issues, pull requests, code search, review comments, and release context | First install when work starts from GitHub. |
| Context7 | Up-to-date library docs and version-specific code examples | Add when framework or SDK APIs change often. |
| Playwright or Browser | Opening local apps, screenshots, and UI flow verification | Add for frontend and full-stack products. |
| Postgres or Supabase | Schema inspection and SQL debugging | Add only with read-only credentials first. |
| Figma | Design context, frame screenshots, tokens, and asset handoff | Add for design-to-code work. |
| Linear or Notion | Specs, tickets, implementation plans, and decision records | Add after teams agree on access boundaries. |
Recommended Starter Stack
A small MCP setup is easier to trust than a large one. Start with the servers that remove the most repetitive context copying from Claude Code sessions.
Starter: - Filesystem - GitHub Frontend: - Filesystem - GitHub - Playwright or Browser Docs-heavy: - Filesystem - GitHub - Context7
When Context7 Belongs In The Stack
Context7 is useful when Claude Code needs current documentation for libraries, frameworks, or SDKs. It is a strong fit for fast-moving APIs where old examples can create broken code.
Security Checklist
Review MCP servers like developer infrastructure. The question is not only whether Claude Code can connect, but what the server can read, write, or execute.
- Use read-only tokens for GitHub and databases when possible.
- Keep API keys in environment variables or local secret storage.
- Document who owns each server and how to rotate credentials.
- Add write-capable servers only after the team agrees on review boundaries.
Selection Criteria
Choose MCP servers by workflow value, not novelty. A useful server should make Claude Code more accurate, reduce manual copying, or enable verification that would otherwise be tedious.
- Does it provide context Claude Code repeatedly needs?
- Can it run with narrow permissions?
- Can developers reproduce the same information manually if the server fails?
- Does it improve validation, not just brainstorming?
FAQ
What is the best MCP server for Claude Code?
Filesystem and GitHub are the best general starting points. Context7 is especially useful for current documentation, and Playwright or Browser is useful for frontend verification.
Should I install many MCP servers at once?
No. Add one or two servers, verify them, document permissions, then expand only when a workflow needs more context.
Is Context7 a Claude Code MCP server?
Yes. Context7 can be connected to Claude Code through MCP so Claude can fetch up-to-date documentation during coding tasks.
Should database MCP servers be read-only?
Start read-only whenever possible. Write access should be explicit, reviewed, and scoped to non-production environments unless there is a strong reason.
