Source Intelligence

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.

Claude Code v2.1.239

Editor-provided tools no longer clutter the blocked-tool list

You'll notice
Useful3 Signal2
Permissions

The blocked-tool list no longer fills up with tools your editor supplied that you cannot act on.

What

When Claude Code lists tools that failed a permission check, tools supplied by your editor integration are now filtered out unless they are on a short allowlist, so that list stays about tools you can actually act on.

Details
  • The filter rejects any tool whose name begins with mcp__ide__, which is the prefix for tools the IDE connection provides.
  • Unconditional.
Evidence

mcp__ide__

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