Overview

The MCP Txtai Server enables AI models to interact with Txtai, an AI-powered search engine that builds vector indexes (also known as embeddings) to perform similarity searches. Txtai is widely used for semantic search, retrieval-augmented generation (RAG), and building intelligent applications.

Detailed Usage

store_memory▶

Store new memory content with metadata and tags.

use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "store_memory",
  arguments: {
    content: "Important information to remember",
    tags: ["important"]
  }
});

Returns a confirmation message.

retrieve_memory▶

Retrieve memories based on semantic search.

use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "retrieve_memory",
  arguments: {
    query: "what was the important information?",
    n_results": 5
  }
});

Returns a list of matching memories.

search_by_tag▶

Search memories by tags.

use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "search_by_tag",
  arguments: {
    tags: ["important", "context"]
  }
});

Returns a list of matching memories.

delete_memory▶

Delete a specific memory by content hash.

use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "delete_memory",
  arguments: {
    content_hash: "hash_value"
  }
});

Returns a confirmation message.

get_stats▶

Get database statistics.

use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "get_stats",
  arguments: {}
});

Returns database statistics.

check_health▶

Check database and embedding model health.

use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "check_health",
  arguments: {}
});

Returns the health status of the server.

Installation

Common Use Cases

1. Store and retrieve memories

Store and retrieve memories based on semantic search:

// Store a memory
use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "store_memory",
  arguments: {
    content: "Important information to remember",
    tags: ["important"]
  }
});

// Retrieve memories
use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "retrieve_memory",
  arguments: {
    query: "what was the important information?",
    n_results": 5
  }
});

2. Search by tags

Search memories by tags:

use_mcp_tool({
  server_name: "txtai-assistant",
  tool_name: "search_by_tag",
  arguments: {
    tags: ["important", "context"]
  }
});
