What is Personal Context Technology (PCT)?
PCT lets you structure personal data that AI assistants use for personalized responses. Your context is preserved between sessions, and you control where data is stored and how it is used.

It implements a server for Personal Context Technology (PCT) using the Model Context Protocol (MCP). This server enables AI assistants like Claude to access and update personalized context data, creating persistent memory between sessions.
Clone the repository, install dependencies with npm install, build with npm run build, and start with npm start. Then configure Claude Desktop by editing claude_desktop_config.json to point to the built dist/index.js. After restarting Claude Desktop, you can access context data via MCP tools and resources.
updateContext toolPCT lets you structure personal data that AI assistants use for personalized responses. Your context is preserved between sessions, and you control where data is stored and how it is used.
After building the server, edit Claude Desktop’s `claude_desktop_config.json` (located in `%AppData%\Claude Desktop\` on Windows, `~/Library/Application Support/Claude Desktop/` on macOS, or `~/.config/Claude Desktop/` on Linux) to add the server with the `node` command and the path to `dist/index.js`.
Use the `updateContext` tool. For example, prompt Claude: “Update my learning_style in preferences to ‘visual and hands-on’.”
By default, context data is stored in `data/personal_context.json` inside the project directory. You can change storage location or switch to user‑specific files for multi‑user support.
The default transport is stdio (for local development). You can switch to HTTP transport by editing `src/index.ts` and configuring a port and CORS settings.
