How to Use the ToolJet MCP in LlamaIndex

Q: How does ToolJet work with LlamaIndex?

LlamaIndex uses the MCP tools to pull data via querytable or other functions. It then transforms that live API output into vector embeddings for semantic search.

Q: Can I query past configurations using ToolJet and LlamaIndex?

Yes. By indexing the results from tools like listtables, your system can answer questions about previous database structures or available data points.

Q: How does the data flow in ToolJet and LlamaIndex?

Data moves from the database, through the tool execution (querytable), into memory as text, and finally gets indexed by the client into a vector store.

Index ToolJet data for knowledge-augmented AI using LlamaIndex's vector stores.

Querying Live Data into Knowledge Bases

ToolJet’s `query_table` tool allows you to pull real database information that can be indexed. Instead of just printing a result, this data becomes part of your searchable knowledge base. Your RAG app reads the API output and grounds its answers in actual records from the ToolJet Database, avoiding guesses.

Automated Data Indexing

The `list_tables` tool helps you discover all available data sources. Your indexer can use this list to build out multiple separate knowledge indexes, one for each table in the database. This mechanism means your search doesn't just look at documents; it looks at structured, live API metadata.

Connecting Actions and Knowledge

When a user needs to write data, they can use `insert_row`. After the data is inserted via this tool, you can immediately query that new record, making it available for indexing in subsequent steps. It closes the loop: action taken, result indexed, and answer provided.

Setup guide

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

Common questions about ToolJet MCP in LlamaIndex

LlamaIndex uses the MCP tools to pull data via `query_table` or other functions. It then transforms that live API output into vector embeddings for semantic search.

Yes. By indexing the results from tools like `list_tables`, your system can answer questions about previous database structures or available data points.

ToolJet touches structured records and metadata within its databases. The key is that the output from `query_table` provides perfectly formatted, indexable text chunks.

It's great for triggering external processes whose results you want to capture. The resulting output can then be added to your knowledge base for later querying.
