About Memory MCP 服务器
Memory MCP Server is an MCP server for managing knowledge graphs, with interactive, command-line, and JSON-based startup options. It supports graph operations and automatic persistence, plus an experimental feature for stories based on graph context.
Key features
- 01Interactive, CLI, and JSON startup
- 02Create and delete entities and relations
- 03Search nodes and read the graph
- 04Add and delete observations
- 05Persist data automatically
- 06Expose graph-based short-story resources
Use cases
- 01Maintain entities, relations, and observations
- 02Search nodes or read the full graph
- 03Save graph data for later use
- 04Retrieve a graph-based story by topic
MCP support
The server supports MCP tools, resources, and sampling, exposing knowledge-graph operations and short-story resources to MCP clients.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

基于 MCP Servers - memory 改造的知识图谱管理服务器
功能特点
- 支持多种启动方式:交互式、命令行、JSON配置
- 生成符合知识图谱知识背景的短故事(实验)(查看
mcp_client.py中的handle_sampling_message函数) - 完整的知识图谱管理功能
- 支持MCP协议:tools、resource、sampling
- 自动数据持久化
- 灵活的配置选项
快速开始
启动方式
- 交互式启动 直接运行程序(双击),按提示输入配置:
- 程序会提示输入端口号(默认8080)
- 程序会提示输入内存文件路径(默认为程序所在目录的memory.json)
2. 命令行传参
启动服务
mcp_server_memory.exe --port 8080 --memory-path ./memory.json
3. JSON配置启动
通过管道传入JSON配置:
echo '{"jsonrpc": "2.0","method": "start","id": 2,"params":{"port": 8080, "memory_path": "./memory.json"}}' | ./mcp_server_memory.exe
获取帮助信息
echo '{"jsonrpc": "2.0","method": "help","id": 1}' | mcp_server_memory.exe
配置项
| 参数 | 说明 | 默认值 |
|---|---|---|
| port | 服务器监听端口 | 8080 |
| memory_path | 数据存储文件路径 | ./memory.json |

数据持久化
- 数据以JSON行格式存储
- 自动保存最新配置到
config.json - 支持相对/绝对路径
- 自动创建不存在的目录
注意事项
- Windows系统推荐使用
\或\\作为路径分隔符 - 确保程序对存储路径有读写权限
- 首次运行自动创建存储文件

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
