DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.227

A failing MCP credential read no longer aborts the request

You'll notice
Useful3 Signal1
MCP

An unreadable MCP credential store no longer kills your request; you get a retryable message.

What

Token lookups in the MCP authentication paths now return nothing on failure rather than throwing, and an unreadable credential store gets its own message saying nothing was sent and the request can be retried.

Details
  • The message reads: Stored credentials for MCP server "name" could not be read right now. Nothing was sent. Retry the request.
  • MCP connection-timeout errors are now built by a shared helper instead of inline.
Evidence

Stored credentials for MCP server "${e}" could not be read right now. Nothing was sent. Retry the request.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
