What are the runtime requirements?

Node.js v16 or higher and npm v7 or higher are required. No external databases or services are needed beyond the local file system.

Where does the knowledge graph data live?

Data is stored in two files per domain: a memory file (default ` /memory.json`) and a sessions file (default ` /sessions.json`). Paths can be customized with environment variables `MEMORY_FILE_PATH` and `SESSIONS_FILE_PATH`.

What credentials does it need?

It reads `MEMORY_FILE_PATH`, `SESSIONS_FILE_PATH` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the MCP Context Manager MCP Server?

MCP Servers for persistent context across work sessions using knowledge graphs

What the server does

A collection of Model Context Protocol (MCP) servers to enhance AI models with persistent context across work sessions throughout the project lifecycle.

Persistent Context — Easily buildcontext, loadcontext, and deletecontext as you progress from idea to production/publication/completion
Efficienct Access — Let AI models grab the exact context they need when they need it
Session Management —
Cross-Domain Support — Work with multiple knowledge domains through a single interface, including creating relationships between entities in different domains

Credentials and setup notes

Node.js v16 or higher - npm v7 or higher

Frequently asked questions

It uses knowledge graphs to free up the AI’s context window (performance) and minimize token cost (efficiency), providing persistent, organized context across sessions.
