Unclear It is unclear whether the message and the retry are switched on for everyone or only where a remotely controlled setting allows them.

What

MCP servers are add-on programs that give Claude Code extra tools. Two new connection error codes, CONNECT_SUSPENDED and CREDENTIAL_STORE_UNAVAILABLE, sit next to CONNECT_TIMEOUT.

  • Suspended connects: when a connection times out because your computer went to sleep or its clock changed while connecting, Claude Code now reports it as suspended rather than a plain timeout. The message reads: 'MCP server "..." connection timed out. Your computer went to sleep or its clock changed while connecting.' Claude Code then reconnects a limited number of times, and the usual failure bookkeeping for plugin servers is skipped. Before, this counted as an ordinary timeout and the normal failure path always ran. This path sits behind tengu_mcp_connect_suspend_redial, and the existing timeout retry setting tengu_mcp_connect_timeout_retry still falls back to true; nothing has been read about either.
  • Credential store unavailable: a new error is raised when an MCP server's saved credentials cannot be read, or were read only after a request had already gone out without them, so the request did not run. On macOS the message suggests unlocking the keychain.

Why

Opening a laptop after sleep is less likely to leave MCP servers failed after a false timeout, and a locked keychain now shows a clear fix instead of an unexplained login failure.
