Use this, not that: MCP servers for docs, GitHub, and browsers
MCP servers are not interchangeable. Pick the official server for the system you actually need to touch.
First pick
Context7
Start with Context7 if the main failure mode is stale library docs. It has an official Free plan (1,000 API calls/mo) and Pro at $10/seat/mo. Add GitHub MCP, Playwright MCP, or Chrome DevTools MCP for those jobs — they are official and free/open source, with your existing GitHub or browser costs on top.
Use this, not that
Context7
Use this when
Your agent keeps inventing APIs and you want current library documentation in context.
Not that when
The job is repo operations, browser driving, or your own product docs site (see GitHub MCP, Playwright MCP, or Mintlify).
GitHub MCP Server
Use this when
The agent should open issues, read PRs, or work with GitHub repositories through the official server.
Not that when
You only needed better library docs, or you are not using GitHub.
Playwright MCP
Use this when
The agent should automate a real browser for flows or tests, using Microsoft’s official server.
Not that when
You only need DevTools-style inspection (Chrome DevTools MCP) or no browser at all.
Chrome DevTools MCP
Use this when
You want official Chrome DevTools inspection and debugging exposed to the agent.
Not that when
You are writing end-to-end tests or multi-step UI automation — Playwright MCP is the better fit.
