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.

Tools can declare whether they run remotely; Bash is the first, and it is scaffolding

Remote Execution

Tools now say whether they can run on a remote device; Bash says yes but nothing ships.

Remote-execution descriptors exist and Bash declares support, but the schema extension returns an empty object.

What

Every tool now carries a remote-execution descriptor, defaulting to unsupported. Bash declares support and names three inputs it refuses when running remotely: dangerouslyDisableSandbox, run_in_background and _simulatedSedEdit. No user-facing flag turns any of this on, and the schema extension Bash spreads in returns an empty object, so no new options actually ship.

Details
  • The descriptor is stripped out before tools are advertised to MCP clients.
  • Separately, IDE diff tabs are suppressed for tool calls marked as running for remote execution.
Evidence

remoteExecution: { supported: !0, refusedInputFields: DRi }

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