Frequently asked questions
What is an MCP server?
An MCP (Model Context Protocol) server is a plugin that gives Claude Code direct access to external services like GitHub, Slack, or databases. You install them with a single command and Claude can then use those services natively.
How many MCP servers can I run at once?
There is no hard limit. Most developers run 3-5 MCP servers covering their core workflow (e.g. GitHub, a database, and Slack). Each server runs as a lightweight process.
Are MCP servers safe to use?
Verified MCP servers from Anthropic and major vendors are safe. They run locally and you control what permissions they get. Always review the source code of community servers before installing.
How do I install an MCP server?
Run the install command in your terminal (usually starting with 'claude mcp add'). The server will be available in all future Claude Code sessions.
