Claude Code v2.1.323 ·

New linked_computer tool category with a fail-closed fallback

MCP tools can now be classed as linked_computer, and if the restriction lookup fails for them, an enforced fallback applies instead of nothing

Unclear What Claude Code does with this category, such as whether it changes what a user sees or how these tools behave, is not stated.

What

Claude Code sorts MCP tools (tools added by add-on programs) into categories. There is now a linked_computer category, which applies to tools that act on a computer linked to the session.

  • Classifying MCP tools can now return linked_computer for tools that match a new check. Before, it returned only browser, computer_use, simulator or nothing. Browser detection was folded into one helper.
  • When the lookup that decides a restriction verdict fails with an error, Claude Code now checks a condition. If the condition holds, it returns an enforced verdict with flagSource "fallback" and family linked_computer. Before, it logged the error and returned no verdict.

Why

Tools for linked computers are treated as their own group. If the lookup fails, the restriction stays in force for them rather than being dropped.
