  • analyze-project: Generates documentation for all React components in a project folder
  • list-projects: Lists all projects under the root folder

Installation

# Clone the repository
git clone https://github.com/azer/react-analyzer-mcp.git

Using with Claude

  1. Enable MCP server in the Claude Desktop config:
{
"react-analyzer-mcp": {
"command": "node",
"args": [
"/Users/azer/code/sandbox/react-analyzer-mcp/build/index.js"
]
}
}
  1. Connect Claude to your MCP server using the Claude Shell.
  1. Use the tools directly in Claude conversations:
Analyze my project's React components in the "ui" folder.

Or:

What React components do I have in my project?

Examples

Analyzing a project folder:

Input:

Can you analyze the components in my "foobar" folder?

Output:

# Components

What tools does React Analyzer expose?

3 in total: 3 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is React Analyzer safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does React Analyzer need?

How does React Analyzer run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as react-analyzer-mcp at 0.1.0.

How current is this page?

The grade is for one exact copy of the source (a0c76ea9ed99), read on 2026-10-08. The repository is watched and re-audited when it changes.
