TxtAI Assistant MCP Server: Seamless Integration for Enhanced AI Capabilities

Overview: What is TxtAI Assistant MCP Server?

TxtAI Assistant MCP Server is an implementation of the Model Context Protocol (MCP) designed to provide semantic search and memory management functionalities. Leveraging robust capabilities from the open-source txtai project, this server enhances AI applications such as Claude Desktop by enabling them to maintain and query contextual memories efficiently.

Key Features & MCP Capabilities

TxtAI Assistant MCP Server is built on top of txtai, a powerful semantic search engine. With integration into the MCP protocol, this server offers several key features that significantly boost the capabilities of AI applications:

1. Semantic Search Across Memories: The server supports advanced semantic search across stored memories, helping to retrieve relevant information quickly and accurately.
2. Persistent Storage: Memories are stored in a file-based system ensuring data durability and easy retrieval.
3. Tag-Based Memory Management: Memories can be organized and retrieved using tags, making it easier to find specific pieces of information.
4. Memory Statistics & Health Monitoring: Comprehensive tools for monitoring the health of memory storage and embedded models.
5. Automatic Data Persistence: Ensures that data is consistently saved across operations.
6. Comprehensive Logging: Logs provide detailed insights into server operations.
7. Configurable CORS Settings: Enhances security and flexibility by allowing customizable Cross-Origin Resource Sharing settings.

MCP Architecture & Protocol Implementation

TxtAI Assistant MCP Server implements the Model Context Protocol (MCP) to facilitate seamless integration with a wide range of AI applications. The architecture ensures that the server operates efficiently while adhering strictly to the MCP protocol standards. Here’s an overview of how it works:

• Client Interaction: Clients like Claude Desktop, which support the MCP protocol, can interact with the server using predefined tool commands and methods.
• Tool Commands & Methods: The server supports various MCP tools for storing, retrieving, and managing memories, including store_memory, retrieve_memory, search_by_tag, delete_memory, get_stats, and check_health.

Getting Started with Installation

To get started, follow these steps:

1. Clone the Repository:

   git clone https://github.com/yourusername/txtai-assistant-mcp.git
   cd txtai-assistant-mcp
   

2. Run the Start Script:

   ./scripts/start.sh
   

This script handles:
