What
MCP servers are outside tools Claude Code can connect to. OAuth is a standard way of signing in to them. The settings schema, the rules that describe valid settings, now tags each OAuth mode with a minimum version:
dcr:availableInVersion"1.15200.0"byo:availableInVersion"1.15200.0"hosted:availableInVersion"1.32885.1"
Why
The schema now records from which version each OAuth mode can be used, so a configuration can be checked against it.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say which product these version numbers refer to.
