cli never mined documented JSON

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.

(Research preview) MCP servers whose channel 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 2026-09-26.

No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.

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.

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.
