## Description
Read-only view of what fills a Mac: disk usage, cleanup candidates, largest items, app leftovers.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

## Documentation

## What CoreTend MCP server does

The CoreTend MCP server exposes local Mac storage information to an AI assistant through Model Context Protocol. Its purpose is inspection rather than file removal: an agent can use it to understand what occupies disk space, locate unusually large items, review possible cleanup targets, and identify application leftovers.

This is useful when a developer wants an assistant to answer questions about a Mac’s storage without granting the assistant a general-purpose deletion workflow. The repository also contains a graphical application and command-line functionality, but the MCP entry point is intended for connecting CoreTend’s read-only inspection to an AI client.

## How it works

CoreTend runs locally through its npm-distributed command. The MCP process is started with `npx -y coretend mcp`, allowing an MCP-compatible client to invoke CoreTend’s storage inspection capabilities. The available information comes from the Mac being inspected rather than from a remote account or hosted service.

The broader CoreTend application divides storage work into areas such as a home-folder space view, cleanup review, and application analysis. For the MCP use case, the supported scope is the read-only view described by the project listing: disk usage, cleanup candidates, largest items, and app leftovers. It also says that Full Disk Access may be needed to read Mail, Safari, and application data; without that permission, macOS limits what can be read.

## Setup and configuration

Install or invoke the package from npm, then configure the MCP client to launch:

```sh
npx -y coretend mcp
```

CoreTend supports macOS 14 Sonoma or later on both Apple silicon and Intel.

No environment variables are documented for running the MCP command. The project does not describe account setup, API credentials, or a remote service requirement. macOS permissions can affect the completeness of scan results, especially for protected Mail, Safari, and application data.

## Tools and capabilities

The CoreTend MCP server is suited to read-only storage questions, including:

- Inspecting overall disk usage on a Mac.
- Finding large files or other large items.
- Reviewing potential cleanup candidates.
- Checking for files left behind by installed applications.
- Supplying local storage context to an AI assistant without authorizing permanent deletion.

## Limitations and notes

The CoreTend MCP server should be treated as an inspection interface, not as a cleanup executor. The project describes its storage view as read-only, while the desktop application separately moves reviewed items to the macOS Trash rather than erasing them permanently. That application behavior should not be assumed to be available through MCP.

Results may be incomplete when macOS permissions block access to protected locations. The project supports English and French according to the macOS language setting. It also states that update checking can be disabled in settings and that no account or telemetry is used.
