How to Use the Treblle MCP in LlamaIndex

Q: How does Treblle help LlamaIndex create a knowledge base?

The ingestapidata tool feeds API request and response data into your vector store. This process allows the MCP Server's output to become searchable knowledge, going beyond simple document indexing.

Q: What kind of data can LlamaIndex index using Treblle?

The server handles API request and response data. The ingestapidata tool ingests these logs directly, allowing you to build a comprehensive knowledge base around your application's network activity.

Q: Is the data processed by Treblle safe for LlamaIndex?

Yes. The ingestapidata tool automatically masks all sensitive fields—like passwords and SSNs—before they are transmitted or indexed, ensuring data privacy.

Q: Can I query past API sessions using Treblle with LlamaIndex?

You can. By indexing the output of ingestapidata, you build a historical record. Your RAG application then queries this index, giving answers grounded in actual previous API data.

Indexing Live API Traffic

The `ingest_api_data` tool allows you to monitor and analyze API traffic, ingesting both requests and responses. This process makes live data available for indexing into your vector store. Instead of just querying documents, LlamaIndex can now query the results from this MCP Server. You're building a searchable knowledge base grounded in real-world API calls.

Grounding RAG with API Data

Don't rely on hallucinations. By using `ingest_api_data`, you combine live API data and documents into one unified index. The search results are now verifiable against actual, observed network traffic. This capability means your queries can reference specific request/response pairs documented by the MCP Server, dramatically increasing the factual accuracy of your RAG application.

Structured Data Querying

The `ingest_api_data` tool provides structured API logs that LlamaIndex can process efficiently. It automatically handles sensitive data by masking fields like SSNs and CCs before indexing. This means you're not just searching text; you're querying structured insights about how your APIs interact, making the index much richer.

Setup guide

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