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.

ToolSearch (renamed from MCPSearch)

What

The MCPSearch tool has been renamed to ToolSearch to better reflect its ability to search for and load both MCP tools and deferred built-in tools.

Usage: The tool works the same way but with the new name:

ToolSearch with query: "select:NotebookEdit"
ToolSearch with query: "slack"
Details
  • Direct selection mode: Use select:<tool_name> for exact tool loading
  • Keyword search: Use natural language to find relevant tools
  • Now supports loading deferred built-in tools in addition to MCP tools
  • Documentation updated throughout to reference the new name
Evidence

aj at line 280183 (tool name constant, contains "ToolSearch")

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