MCP: add tools.* namespace for plugin discovery + activation#5996
Merged
Conversation
Four read-only or activate-style tools backed by RibbonSchemaHolder. Lets an
LLM enumerate and operate plugins by id without walking the ribbon UI tree:
- tools.listAll — sorted ids of every registered ribbon item
- tools.listActive — ids of currently-open state plugins
- tools.getInfo(ids) — batch metadata: caption, tab, type, active, status,
tooltip, helpLink (missing ids land in `missing`)
- tools.action(id) — clicks/toggles by id; mirrors RibbonMenu's
skip-availability-check-when-active rule
No new public API on RibbonMenu/RibbonSchemaHolder — uses existing primitives.

May be better name it "MRMcpTools.cpp" as below item?

Follow-up to #5972 / #5980 / #5982 (MCP scene/viewer/ui namespaces). Adds a
tools.*namespace so LLMs can enumerate and operate ribbon plugins by id without walking the ribbon UI tree.Tools
tools.listAll— sorted array of every registered ribbon item id (~300). Tab-independent, unlikeui.listAllEntrieswhich only sees the active ribbon tab.tools.listActive— ids of currently-open state plugins (typically 0–2).tools.getInfo({ids})— batch metadata lookup. Per-id row:caption,tab,type(button/stateBlocking/stateNonBlocking),active,status(available/disabled: <reason>),tooltip,helpLink. Ids absent from the schema land in a parallelmissingarray instead of erroring the whole call.tools.action({id})— clicks / toggles by id. State plugins toggle; one-shot buttons run their action. MirrorsRibbonMenu::getRequirements_'s skip-availability-check-when-active rule.No new public API — built directly on
RibbonSchemaHolder::schema(),RibbonMenuItem::action() / isActive() / isAvailable() / getDynamicTooltip(), andRibbonSchemaHolder::findItemTab.Verification
