### Description (declared)

# Spatial Memory MCP Server

[![PyPI version](https://badge.fury.io/py/spatial-memory-mcp.svg)](https://pypi.org/project/spatial-memory-mcp/)
[![Python 3.10+](https://img.shields.io/badge/python-3.10+-blue.svg)](https://www.python.org/downloads/)

A persistent semantic memory system for LLMs via the [Model Context Protocol](https://modelcontextprotocol.io/) that treats knowledge as a navigable landscape, not a filing cabinet.

> **Version 1.11.3** — Production-ready with 2,500+ tests across Windows, macOS, and Linux.

**Your AI assistant forgets everything between sessions. Spatial Memory fixes that.** It gives Claude Code, Cursor, and any MCP client a persistent brain — memories that fade when stale, sharpen with use, and organize themselves into a navigable knowledge graph. Install in one command, capture knowledge automatically, and let your AI build on what it learned yesterday.

## Why Spatial Memory?

Most memory servers store and retrieve. Spatial Memory **thinks** about your knowledge.

### Memories That Fade Like Yours Do

Other memory tools treat every piece of information as equally important forever. Spatial Memory applies **time-based decay** — old, unused memories gradually lose importance while frequently accessed knowledge stays sharp. The result: your AI assistant surfaces what's relevant *now*, not what was relevant six months ago. Decay is automatic and configurable — adjust half-life, decay curves (exponential, linear, step), and minimum importance floors. Memories accessed frequently decay slower, just like human recall.

**Why this approach?** The cognitive memory model is inspired by established research:
