Memory MCP

🚀 Memory MCP Server

A knowledge graph management server modified based on MCP Servers - memory

• Generate short stories that fit the background of the knowledge graph (experimental) (see the handle_sampling_message function in mcp_client.py).
• Complete knowledge graph management functions.
• Support the MCP protocol: tools, resource, sampling.
• Automatic data persistence.
• Flexible configuration options.

🚀 Quick Start

Startup Modes

1. Interactive Startup Run the program directly (double-click) and input the configuration as prompted:

   • The program will prompt you to enter the port number (default is 8080).
   • The program will prompt you to enter the path of the memory file (default is memory.json in the program directory).

2. Command-line Parameter Passing Start the service:

mcp_server_memory.exe --port 8080 --memory-path ./memory.json

3. JSON Configuration Startup Pass the JSON configuration through the pipeline:

echo '{"jsonrpc": "2.0","method": "start","id": 2,"params":{"port": 8080, "memory_path": "./memory.json"}}' | ./mcp_server_memory.exe

Get help information:

echo '{"jsonrpc": "2.0","method": "help","id": 1}' | ./mcp_server_memory.exe
