Lumail plugin — MCP basics

The Lumail plugin connects Claude Code and Codex to one Lumail organization over an OAuth MCP connection at https://lumail.io/mcp. There is no API token to create, paste, or store: the host runs the browser OAuth flow, the user picks the organization, and the access token stays in the host's credential store.

Before the first tool call

Confirm the server is connected and authenticated.
