Our Top MCP Servers
Our top automation pick is Computer Use in OpenAI's Codex desktop app, which drives Mac apps directly rather than only the browser; it replaces Playwright MCP at #1 and is a Codex plugin, not an MCP server. Among MCP servers, Context7 leads for documentation retrieval, and the unmaintained Postgres reference server still works for read-only database access.
The Picks
- #1
Computer Use (Codex desktop)
Best for desktop automationOpenAI Codex's Computer Use drives your Mac apps directly: it clicks, types, and works across desktop apps, with an in-app browser that captures both screenshots and DOM elements, and a Locked mode that keeps tasks running after your screen locks. It is a plugin of the Codex desktop app rather than an MCP server, and it is macOS-only, unavailable in the EEA, UK, and Switzerland at launch. It replaces Playwright MCP at #1 because it automates the whole desktop, not only the browser; Playwright remains a solid choice for pure browser workflows.
- #2
Context7
Best for documentationRetrieves up-to-date library docs directly into your AI context. Eliminates hallucinated API references by grounding responses in real documentation.
- #3
Postgres MCP
Best for database accessRead-only access to a PostgreSQL schema from your AI tool, for exploring structure and drafting queries against real tables. Checked August 12, 2026: this is a reference server that is no longer maintained (its repository is archived and the last npm release of @modelcontextprotocol/server-postgres is 0.6.2, December 2024). It still installs and works; prefer an actively maintained alternative for anything you depend on.
- #4
GitHub MCP
Best for repo operationsManage PRs, issues, and code reviews through AI. Streamlines GitHub workflows without leaving your AI coding environment.
- #5
Filesystem MCP
Best for file operationsRead, write, and search files with AI assistance. A foundational MCP server that enables AI tools to interact with your local filesystem safely.

Changelog
- August 12, 2026: Computer Use in OpenAI's Codex desktop app replaces Playwright MCP at #1. It is a desktop-automation plugin rather than an MCP server, and it takes the top slot because it drives Mac apps directly instead of only the browser. Playwright MCP remains a solid choice for pure browser automation. Other ranks unchanged.
- August 2026: Maintenance re-check. Postgres MCP flagged as an unmaintained reference server (repository archived; last npm release December 2024). Playwright MCP and Context7 confirmed actively developed. The other picks were not re-reviewed and the ranking is unchanged.
- March 2026: Initial picks published
Frequently Asked Questions
What is an MCP server?
An MCP server is a standardized interface that connects AI models to external tools and data sources, following the Model Context Protocol.
Do I need all of these MCP servers?
No. Start with one or two that match your workflow. Computer Use (if you run Codex on macOS) and Context7 cover most development needs; add the GitHub or Filesystem servers when your workflow lives there.
Is Computer Use an MCP server?
No. Computer Use is a plugin of OpenAI's Codex desktop app on macOS, not a Model Context Protocol server. We rank it here because it fills the same job readers used Playwright MCP for: letting an AI agent operate the machine it runs on.
