What Is MCP and Why Does It Matter?

Model Context Protocol (MCP) is an open standard that lets AI assistants like Claude connect to external tools and data sources. For Claude Code users, MCP servers are the difference between an AI that only reads your local files and one that can query your database, create GitHub issues, and control a browser — all without leaving your editor.

The 10 MCP Servers Worth Installing First

1. GitHub MCP Server

The official GitHub MCP server lets Claude create issues, review PRs, and manage repositories without leaving your coding context. Essential for any developer using GitHub.

2. Playwright MCP

Control a real browser from Claude. Useful for automated testing, web scraping, and debugging frontend issues by watching Claude interact with your app in real time.

3. Figma Context MCP

Pull design specs, component properties, and color tokens directly into your coding context. Eliminates the constant alt-tab between Figma and your editor.

4. Supabase MCP

Query your Postgres database, inspect schemas, and run migrations directly from Claude. The official Supabase MCP is stable and well-documented.

5. Context7

Fetches up-to-date library documentation and injects it into Claude's context. Stops Claude from confidently writing code using outdated APIs.

6. Linear MCP

Create issues, update statuses, and manage your sprint backlog without leaving Claude Code. Especially useful for turning Claude's suggestions into tracked work items.

7. Notion MCP

Read and write Notion pages from Claude. Useful for updating documentation, meeting notes, or project specs as you work.

8. Chrome DevTools MCP

Connect Claude to a running Chrome instance. Inspect DOM, read console errors, and debug network requests — Claude can see what your browser sees.

9. PostgreSQL MCP

Direct Postgres access without Supabase. Connect to any Postgres database and let Claude write and execute queries, inspect indexes, and explain query plans.

10. Filesystem MCP

Gives Claude safe, sandboxed access to specific directories on your machine. Useful for letting Claude manage config files, logs, or project assets outside your editor's workspace.

How to Install MCP Servers in Claude Code

All MCP servers follow the same installation pattern. Add them to your ~/.claude/config.json or project-level .claude/config.json:

{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "your-token" }
    }
  }
}
