## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 86/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 188 tokens (~188/item across 1 items; 1 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

### `search_component_registries` (~188 tokens)

Search shadcn-style component registries

Search BlockDex, a cross-registry index of shadcn-compatible components, blocks, hooks and libraries from dozens of public registries. Use when a user wants a UI component and you would otherwise hand-write it — "is there a date range picker block", "which registries have a kanban board". Returns the registry, the item type and its dependencies so you can judge the cost of pulling it in.

Input parameters:

- `access` (string): Filter by whether the item is free to install: free, paid, unknown.
- `kind` (string): Filter by item kind: component, block, hook, example, lib, theme, other.
- `limit` (number): How many to return, 1-10. Default 5.
- `q` (string, required): What the component does. e.g. "data table", "auth form", "kanban".
