Memory MCP Server

Knowledge Graph Storage: Maintain a persistent graph of entities and their relationships
Entity Management: Create, retrieve, update, and delete entities with custom types
Relation Tracking: Define and manage relationships between entities in active voice
Observation System: Add and remove observations about entities over time
Powerful Search: Find relevant nodes by name, type, or observation content
Persistent Storage: Data persists between sessions in a simple JSON format

The easiest way to install is with the one-line installer, which automatically downloads the latest version and installs it to ~/.local/bin in your home directory:

curl -fsSL https://raw.githubusercontent.com/okooo5km/memory-mcp-server/main/install.sh | bash

The installer will:

Create ~/.local/bin if it doesn't exist
Add this directory to your PATH (in .zshrc or .bashrc)
Download and install the latest version
Make the binary executable

mkdir -p ~/.local/bin
cp $(swift build -c release --show-bin-path)/memory-mcp-server ~/.local/bin/

   Make sure ~/.local/bin is in your PATH by adding to your shell configuration file:

The server supports the following environment variables:

 MEMORY_FILE_PATH: Custom path for storing the knowledge graph (optional)

   If not specified, defaults to memory.json in the current working directory

  * Can be an absolute path or relative to the current working directory
You can check the configured file path in the server logs when starting the server.

Add to your Claude settings:

Add the following configuration to your Cursor editor's Settings - mcp.json:
