What

Connectors link Claude Code to outside tools through MCP, a standard way of plugging in tools. Several things change in how files are passed to them:

  • When CLAUDE_CODE_REMOTE is true, Claude Code now waits until the file store has fully taken a file before reading it. Before, it read the file straight away.
  • If that wait fails, it logs that it did not wait for the file store to take the file.
  • When an upload fails, the error text is no longer logged, because it can name the file or the upload address.
  • Claude Code now keeps track of files that connector servers report as delivered.
Why

In remote sessions, an attached file could be read before it had finished being written. Waiting first stops that, and the logs no longer reveal file names or upload addresses.
