How It Works

Three simple steps to supercharge your AI workflow

1

Install once

Add Stash to your MCP configuration. Works with Claude Desktop, Claude Code, and any MCP-compatible AI tool.

2

Save context

Store information with tags in any MCP tool. API docs, code snippets, research notes - anything you need later.

3

Use everywhere

Retrieve saved context in any other MCP tool. Your context follows you across your entire AI workflow.

Privacy First

Your data never leaves your machine. All contexts stored locally on your device. Cloud sync is optional when it arrives in Phase 2.

Lightning Fast

Built with .NET 8.0 for optimal performance. Save and retrieve contexts in milliseconds, not seconds.

Smart Organization

Tag your contexts for easy retrieval. Search by name, content, or tags to find exactly what you need.

Cross-Platform

Works on macOS, Windows, and Linux. Self-contained binaries mean no dependencies to install.

Quick Installation

Get started in 2 minutes

1 Run the installer

Choose your platform and run the one-line installer:

macOS / Linux:

curl -sSL https://stashmcp.com/install.sh | bash

Windows (PowerShell):

iwr https://stashmcp.com/install.ps1 -UseBasicParsing | iex

The installer will download the latest version, verify checksums, and install to your system.

2 Add to Claude Desktop Config 

{
  "mcpServers": {
    "stash": {
      "command": "/usr/local/bin/stash",
      "args": []
    }
  }
}

Config location: ~/Library/Application Support/Claude/claude_desktop_config.json

3 Restart & Start Using

Restart Claude Desktop and start saving contexts! Ask Claude to "save this API documentation as 'stripe-api' with tags 'api,payment'"

Frequently Asked Questions

Do I need a Stash account?

No! Everything runs locally on your machine. No accounts, no cloud, no subscriptions.

Will this work with ChatGPT/GitHub Copilot?

Yes, if they support MCP (Model Context Protocol). Currently works out of the box with Claude Desktop and Claude Code. Other tools are adding MCP support.

Is my data private?

Yes! Everything stays on your machine. Contexts are stored as plain JSON in ~/.stash/contexts.json. Optional telemetry only tracks anonymous usage stats (no content).

Can I sync across devices?

Not yet, but cloud sync is coming in Phase 2! You can manually sync the ~/.stash/ folder via Dropbox or Git for now.

Is it free?

Yes! Stash is free during beta. When cloud sync launches (Phase 2), there will be a free tier and optional paid tier for advanced features.
