BlockDex: Search shadcn-compatible components across public registries.

VerifiedSTDIODesktop onlyDeveloper Tools

Overview

AI-generated overview

Lets an assistant search shadcn-compatible components, blocks and hooks across public registries and see the dependencies each one pulls in.

What it does
BlockDex MCP exposes a single tool, search_component_registries(q, kind?, access?, limit?), which finds shadcn-compatible components, blocks and hooks across dozens of public registries. Results include the dependencies each item pulls in, so an assistant can compare options before adding code. It is a read-only lookup service with no account or key.
When to use it
Useful when building or extending a front-end project that uses shadcn-style components and you want the assistant to find existing components, blocks or hooks instead of writing them from scratch. Also handy for checking what dependencies a candidate component would add. Not needed if you do not work with shadcn-compatible registries.
Requirements
Runs as a local process over stdio, desktop only. Requires Node.js with npx to run the npm package blockdex-mcp. No API key, signup, or account is needed. The README also documents an optional HTTP mode on a local port.
Before you install
No API key, signup, or credentials are requested, and no environment variables or headers are declared. The tool only searches public registries; the README does not describe any write, install, or delete action, so nothing is modified on your machine by the server itself. Installing via npx runs third-party package code locally, so review the package before use.

Installation

In SourceWeft

  1. Open BlockDex MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
