What is MCPKG?

MCPKG is a knowledge graph system used to store and manage structured information. It uses the subject - predicate - object triple form to represent data relationships, similar to the way the human brain remembers information. The system provides an access interface through the Model Context Protocol (MCP), allowing other programs to easily query and use this structured data.

How to use MCPKG?

Using MCPKG mainly involves two basic operations: 1) Inserting triple data; 2) Querying data relationships. The system provides simple tools and APIs to perform these operations without in - depth knowledge of the underlying implementation.

Use cases

MCPKG is very suitable for application scenarios that need to represent complex relationships, such as knowledge management, recommendation systems, semantic search, etc. It can help organize and understand a large amount of inter - related information.

Main features

Knowledge graph storageStores structured information in the form of a directed graph, where nodes represent entities and edges represent relationships.

Triple operationsSupports creating and querying triple data in the subject - predicate - object form.

Persistent storageSupports serializing and saving data to disk to ensure data is not lost.

MCP service interfaceProvides a standardized program access interface through the Model Context Protocol.

Concurrency safetyThread - safe design, supporting simultaneous access by multiple users.

Advantages and limitations

Advantages

A simple and powerful data representation method, easy to understand and use

High - performance graph structure query ability

Standardized access protocol, easy to integrate

Thread - safe design, suitable for production environments

Limitations

Requires a Go 1.24+ environment to run

The query performance for large - scale graph data may be limited

Currently only supports basic CRUD operations

How to use

Installation and configuration

Ensure that the Go 1.24+ environment is installed, and then use go get to install MCPKG and related dependencies.

Start the MCP server

Run the MCP server program, which will provide the access interface for the knowledge graph.

Insert data

Use the insert_triple tool or API to add triple data to the knowledge graph.

Query data

Use the graph://URI format to query data relationships.

Usage examples

Build a knowledge baseUse MCPKG to build a knowledge base about scientific discoveries, recording the relationships between scientists and their discoveries.

Recommendation systemUse the relationship data in the knowledge graph to provide personalized recommendations for users.
