[DOCS] MCP docs missing collapsed "Queried {server}" display for read/search tool calls

Documentation Type

Missing documentation (feature not documented)

Section/Topic

MCP tool usage display behavior and the interaction with Ctrl+O verbose mode

Current Documentation

No documentation currently exists for the collapsed MCP tool call display. The MCP docs cover server setup, tool search, output limits, and elicitation, but say nothing about how MCP read/search tool calls are displayed in the terminal.

The keybindings page documents Ctrl+O as "Toggle verbose transcript" (app:toggleTranscript) but does not connect it to MCP tool call display.

What's Wrong or Missing?

Changelog v2.1.81: "Improved MCP read/search tool calls to collapse into a single 'Queried {server}' line (expand with Ctrl+O)."

This is a user-visible UI change — MCP read/search tool calls no longer show individual tool call details by default. Instead, they collapse into a single summary line like "Queried my-server". Users can expand the details with Ctrl+O.

Without documentation, users may wonder why MCP tool calls appear condensed or how to see the full details.

Suggested Improvement

Add a note to the MCP docs (e.g., in a "Using MCP tools" or "Tool call display" subsection):

MCP read and search tool calls collapse into a single "Queried {server}" summary line for a cleaner transcript. Press Ctrl+O to toggle verbose mode and see the full tool call details.

Also consider adding a note in the interactive mode keybindings section that Ctrl+O expands collapsed MCP tool calls.

Impact

Medium - Makes feature difficult to understand
