Turn text into searchable indices

Use `extract_topics` to pull entities out of your documents before they enter your vector store. This gives your search queries a massive boost in accuracy because you are matching against refined concepts. Your index becomes smarter when you combine it with `summarize_text`. You store the summary alongside the full text for faster retrieval during query time.

Contextualize data with sentiment

Tag your knowledge base entries with `analyze_sentiment` to filter search results by user tone. It lets you ask questions like 'show me all negative feedback regarding this feature' and get precise hits. This adds a layer of intelligence to your RAG application. You aren't just searching for keywords anymore; you are searching for intent.

Automated data cleaning

Run `detect_language` during your ingestion process to route documents to the correct indices. It keeps your multi-language knowledge base organized and avoids cross-language noise. This MCP Server handles the heavy lifting before the indexing even starts. Your pipeline stays clean and your search results remain relevant.

Setup guide

Set up MeaningCloud MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all MeaningCloud MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to MeaningCloud tools.",
)
response = await agent.run("List recent MeaningCloud data")
