DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs.

MCP server bearer credential rejection: clearer error and automatic retry
What's wrong with this entry?
Anonymous. No account, no email.
What
When an MCP server rejects Claude's session credential with an HTTP 401, the connection is now tagged with a dedicated CLI_OWNED_BEARER_REJECTED error code and the error message explicitly states the credential will be retried on the next refresh cycle. Previously, bearer rejection was handled identically to other connection failures.
Evidence
New bearer rejection handler (search for "CLI_OWNED_BEARER_REJECTED")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
