Indexing tool outputs

When you call `get_word_definition` or `get_word_summary`, the output becomes part of a searchable index. This means your linguistic knowledge isn't just transient; it lives in your vector store. You can build an application that indexes API data alongside documents, making everything queryable by meaning, not just keywords.

Building RAG applications with the MCP Server

LlamaIndex combines live Wiktionary data (like definitions) and static documents into one index. You get answers grounded in actual API calls and your internal files—no hallucinations. The developer builds a unified knowledge base, perfect for corporate learning or specialized research tools.

Querying past sessions

The client lets you query previous MCP tool outputs. You don't have to rely on memory; the system grounds answers in historical API data. This is huge for building reliable applications where context from weeks ago needs to inform today’s answer.

Setup guide

Set up Wiktionary 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 Wiktionary 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 Wiktionary tools.",
)
response = await agent.run("List recent Wiktionary data")

Common questions about Wiktionary MCP in LlamaIndex

LlamaIndex takes the text returned by Wiktionary's tools and indexes it. Instead of just printing a definition, it makes that definition part of a semantic search corpus you can query later.

It’s excellent because you're combining the fresh data from `get_word_definition` with your existing document library. The search result isn't just a match; it's an answer synthesized from both sources.

The primary tools are `get_word_definition` and `get_word_summary`. These allow you to inject highly specific, vetted linguistic information into your knowledge index.

Yes. By including the MCP Server's output in your index resources, you can query historical definitions and summaries as if they were always part of your documentation set.

The server touches linguistic text data: the word definitions and summaries. Since this is indexed, developers must manage resource inclusion carefully to control what gets permanently stored in your vector store.
