Server instructions

Read-only tools over the Commons design-system registry (accessibility-first components for U.S. local governments, https://commonsui.com). Use search_components to discover, get_component to inspect a component's contract, plan_install to see what an install would pull in, and get_setup for project setup facts. This server never writes files — installing is the job of the local CLI: "npx @21stgov/commons add <names>".

Known tools 4

search_components

Search the Commons registry catalog (commonsui.com/r/index.json) with the same case-insensitive matching as `commons search`: the query is matched against each entry's name, title, description, and useWhen lines.

Inferred read-only

get_component

Fetch and validate one registry item (commonsui.com/r/{name}.json), exactly like `commons inspect`.

Inferred read-only

plan_install

Resolve one or more components and their transitive registryDependencies from the registry, in installation order, and report every file that would be created and every npm dependency needed.

Inferred read-only

get_setup

Return the facts needed to set up Commons in a project: the registry URL, the five global-CSS import lines in their required order, the tsconfig path alias, and the init command.
