How to install MCP servers in Claude Code
MCP servers install with a single command. Run the install command in your terminal and the server will be available in all future Claude Code sessions.
1. Run the install command
claude mcp add github -- npx -y @modelcontextprotocol/server-github2. Set any required environment variables
Most MCP servers need an API key or token. Set it as an environment variable in your shell profile:
export GITHUB_TOKEN=ghp_your_token_here3. Or configure in Claude Code settings
You can also add MCP servers directly in your Claude Code settings file (~/.claude.json):
{
"mcpServers": {
"server-name": {
"command": "npx",
"args": ["-y", "@package/server-name"],
"env": {
"API_KEY": "your-key-here"
}
}
}
}4. Verify it works
Start a new Claude Code session and ask Claude to use the server. For example: "List my GitHub repos" or "Show my Postgres tables". Claude will use the MCP server automatically.
Frequently asked questions
Which development MCP server should I install first?
Start with the GitHub MCP server if you use GitHub. It covers PRs, issues, code search, and actions - the operations you do most often during development.
Can I use both the GitHub and GitLab MCP servers?
Yes. Each MCP server runs independently. Install both if you work across GitHub and GitLab repositories.
Do development MCP servers work in CI environments?
Most do. The GitHub, Git, and Docker MCP servers all support headless environments. Check each server's docs for CI-specific configuration.
