Memory MCP Server: Enhancing AI Applications through Universal Adapter Integration

Overview: What is Memory MCP Server?

The Memory MCP Server is a specialized Model Context Protocol (MCP) server designed to provide knowledge graph functionality for managing entities, relations, and observations in memory with strict validation rules. This ensures data consistency and integrity, making it an ideal tool for integrating into various AI applications that require robust context management and metadata handling.

🔧 Core Features & MCP Capabilities

The Memory MCP Server supports a range of core features essential for advanced integration scenarios:

1. Entity Management: It allows the creation, retrieval, and deletion of entities with predefined types such as person, concept, project, document, and more.
2. Relationship Handling: Supports various relation types like knows, contains, uses, etc., ensuring that relationships between entities are accurately defined and maintained.
3. Observation Tracking: Enforces strict validation on observations, guaranteeing they are factual, objective statements with unique values per entity.
4. Data Validation Rules: Implements comprehensive rules for entity names, types, relations, and more to ensure data consistency.
5. Search Functionality: Provides advanced search capabilities that support fuzzy matching and weighted searches based on entity attributes.

These features not only enhance the reliability of AI applications but also facilitate seamless integration with diverse MCP clients via standardized protocols.

⚙️ MCP Architecture & Protocol Implementation

The Memory MCP Server is built around a robust knowledge graph model, utilizing strict validation rules to maintain data consistency. The architecture involves:

1. Validation Module: Ensures input data adheres to predefined rules through detailed validation logic.

🛠️ Advanced Configuration & Security

MCP Configuration Sample

To configure the Memory MCP Server, use the following sample configuration snippet:

{
  "mcpServers": {
    "[server-name]": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-[name]"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}

This configuration ensures that the server is properly initialized with necessary environment variables and commands for smooth operation.
