Overview

AI-generated overview

A hosted shared Markdown memory that AI assistants can read and write, so context carries across tools.

What it does
WhyVault provides a shared Markdown memory store that assistants can read from and write to, letting notes and context persist across different AI clients. It is a hosted remote service rather than a local package, and the provider states the data is hosted in the EU. The manifest does not list individual tools, so the exact read and write operations are not documented here.
When to use it
Worth adding when you want several assistants or sessions to share the same persistent notes and context instead of repeating information each time. Less useful if you only need memory inside a single tool or prefer to keep everything local.
Requirements
A remote MCP endpoint; no local runtime or package is needed. Clients with OAuth support, such as Claude or ChatGPT, can sign in without extra configuration. Other clients must send an Authorization header with a bearer personal access token obtained from the WhyVault app. Network access to the endpoint is required.
Before you install
The Authorization header carries a personal access token, so treat it as a secret and avoid exposing it. Because the memory is shared and writable, anything stored may be readable by every connected assistant, and content is held on a third-party EU-hosted service rather than on your machine.
