Claude Desktop reads its MCP servers from claude_desktop_config.json under the mcpServers key. The documented route to it is Settings, the Developer tab in the left sidebar, then the Edit Config button, which creates the file if it is not there yet. Linux has no published path, because the documentation says Claude Desktop is available for macOS and Windows. Save, then completely quit Claude Desktop and start it again. A window reload is not enough.
| Scope | Path |
|---|---|
| macOS | ~/Library/Application Support/Claude/claude_desktop_config.json |
| Windows | %APPDATA%\Claude\claude_desktop_config.json |
Two documented facts decide whether the entry works: every path in claude_desktop_config.json must be absolute, and a stdio server started here inherits only a limited, platform-dependent subset of environment variables. If node came from nvm or homebrew, paste what `which node` prints instead of the bare word. The .mcpb route avoids both: Claude Desktop ships a built-in Node.js environment.
