}🔴get_component(name)
Fetch the full TypeScript source of a Crucible component, ready to drop into a shadcn-style project. Pro components require an Authorization: Bearer <CRUCIBLE_TOKEN> header (get a token at https://crucibleui.com/account).
Input Schema
{
"type": "object",
"properties": {
"name": {
"type": "string",
"description": "Component name, e.g. 'corona' — find names via search_registry"

How to install a Crucible component into a project: shadcn CLI command, registry config, and npm dependencies.
Input Schema
{
"type": "object",
"properties": {
"name": {
"type": "string",
"description": "Component name, e.g. 'corona'"
}
},
"required": [

],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_usage(name)
Show how to USE a Crucible component correctly: a worked example (its demo source) plus the conventions that make it render — notably the `relative isolate` wrapper that background components require. Call this before writing integration code so the install actually renders.
