Claude Code v2.1.195 26 Jun 2026

MCP Login from CLI with --no-browser

What

MCP servers that require authentication can now be authenticated from the command line, with a --no-browser flag for SSH/headless environments where the browser cannot open.

Usage

claude mcp login <server-name>
claude mcp login <server-name> --no-browser

Details

--no-browser prints the callback URL for manual pasting rather than attempting to open a browser.
Tip: "claude mcp login <name> authenticates an MCP server from the CLI — add --no-browser to paste the callback URL manually over SSH."

Evidence

New CLI tip (search for "claude mcp login <name> --no-browser")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
