`--channels`

A Claude Code CLI flag, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

(Research preview) MCP servers whose [channel](/docs/en/channels) notifications Claude should listen for in this session. Space-separated list of plugin:<name>@<marketplace> entries. Requires Anthropic authentication through claude.ai or a Console API key

Anthropic's own wording. Read off CLI reference, captured 2026-08-28.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Changelog entries naming it

v2.1.239Command-line flag parsing rewritten around an explicit table of value-taking flags
Flags that take values no longer swallow or drop their arguments, and -- is handled.

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the CLI flag does. All CLI flags.
