Claude Code stores user-scope MCP servers in ~/.claude.json (what
'claude mcp add' writes); ~/.claude/settings.json is for permissions
and hooks and rejects an mcpServers key with a schema error, so BCC
was reading (and writing) servers where Claude Code never looks.
If servers are found parked in settings.json, that file is still
listed as 'Claude Code (legacy settings.json)' so they can be copied
into the real config via Copy to. Docs updated; verified against
docs.claude.com/en/docs/claude-code/settings.
