Stellar Memory

Stellar Memory gives an assistant a local, persistent memory store organized with an orbital-mechanics model, running entirely on the user's machine.

What you can do

Stellar Memory is a local MCP server that provides persistent memory for an AI assistant, described as using orbital mechanics to organize stored context. It runs as a local process over stdio and keeps its data in a SQLite database file. Configuration covers the REST API port, the database path, an active project name for memory isolation, and a token budget for context. No tool list is published in the manifest.

When to use it

Worth considering when an assistant should remember information across sessions and the user wants that memory kept locally rather than in a hosted service. The project setting suits keeping separate memory spaces for different work. It is desktop-only, so it is not for browser-based or remote use.

Requirements

Runs as a local process on the user's machine via the npm package stellar-memory over stdio, so Node.js is needed. Optional environment variables: STELLAR_API_PORT (default 21547), STELLAR_DB_PATH (default ~/.stellar-memory/stellar.db), STELLAR_PROJECT, and STELLAR_SUN_TOKEN_BUDGET (default 800). No authentication is declared.
