Claude Code v2.1.323 ·

Reconnecting to web MCP servers during MCP tool search now uses a new remote switch, off by default, and only plain http servers without ALL_PROXY qualify

What

An MCP server is an outside program that gives Claude Code extra tools. During MCP tool search, Claude Code can reconnect to a server that it reaches over the web. That reconnect now depends on a different remote switch, which is off unless it is switched on remotely.

A server now has to meet stricter rules before Claude Code reconnects to it:

  • Its address must use http:. A readable address used to be enough.
  • Neither ALL_PROXY nor all_proxy may be set.
  • A few other checks must pass.

A server that does not qualify is now simply left unconnected and does not count as a failure.

Why

This reconnect stays hidden unless it is switched on remotely, and a server that does not qualify no longer shows up as a failed connection.
