MCP in Claude.

Choose the Claude surface

Claude Code uses the CLI installer and local MCP configuration. Claude Desktop uses its desktop MCP settings. Claude on the web uses the hosted connector and browser OAuth. These are separate clients; do not copy a desktop token into the web connector.

Claude Code

Install the CLI before running the installer. The installer registers Empirical MCP and the native plugin, then the client can complete OAuth.

npm install -g @empirical-gauzza/cli
empirical install

Claude Desktop

Use the installer or add the hosted MCP endpoint in Claude Desktop’s MCP settings, then authorize when the client requests it.

npm install -g @empirical-gauzza/cli
empirical install

MCP endpoint: https://empirical.gauzza.com/mcp

• Open Claude Desktop setup →

Claude on the web

Add Empirical as a custom connector in Claude web, complete browser OAuth, and ask Claude to recall a non-sensitive preference. This path does not require the local CLI.

Support boundary: Use the published connector flow for Claude web. Do not paste a CLI token into the connector settings.
