What
When Claude Code successfully connects to an MCP (Model Context Protocol, a way for Claude to talk to external tools and data sources) server, it now also stores the first-party bearer authentication token for that connection in a new internal lookup table, alongside the existing table of auth providers.
Why
This lets Claude Code track and reuse first-party bearer credentials per connection separately from general auth provider state, which is bookkeeping that supports more reliable authenticated MCP connections.
