Setting up MCP servers in Claude Desktop
Claude Desktop was one of the first MCP clients — Anthropic built the protocol and shipped support for it in Claude Desktop from the start. Every server runs locally over stdio, launched by Claude Desktop itself from the command in your config file; there's no separate process to manage.
Configuration lives in a single JSON file — claude_desktop_config.json — with one mcpServers entry per server. Claude Desktop only reads this file on launch, so a new or edited entry needs a full app restart (not just a reload) before it shows up.
