How to Use the Metorial MCP in LlamaIndex

Q: How does Metorial prevent hallucinations in LlamaIndex?

By feeding live telemetry into your index. Your agent uses metorialgetserverstatus to check node health, ensuring your RAG pipelines get data from active, verified sources instead of guessing.

Q: Can I filter which tools are exposed to my agent?

Absolutely. You use metoriallistservers to identify active workspaces, then limit your agent's access to only the specific tool execution boundaries it needs for the current task.

Index live serverless MCP execution traces directly into your LlamaIndex vector stores for semantic debugging.

Perplexity

Index Live MCP Server Performance into Vector Stores

By querying `metorial_get_usage_metrics`, your agent pulls live performance data and indexes it straight into your vector store. LlamaIndex thrives on fresh data, but logging is usually static. This means you can ask your agent which nodes are running hot. It checks the indexed metrics, compares them with past runs, and gives you an answer grounded in actual server telemetry.

Search Metorial Trace History in LlamaIndex

Your agent uses `metorial_list_traces` to gather transaction logs, then indexes those logs so you can run natural language searches. Stop digging through raw text files to find errors. When an execution fails, the agent calls `metorial_get_trace_details` to pull the precise boundary data. It then matches that error against your historical index to find out if you've seen this exact bug before.

Manage LlamaIndex Knowledge Nodes on Demand

Your agent can run `metorial_deploy_server` to spin up an MCP Server node only when a query requires live external data. Don't keep expensive infrastructure running just to support occasional RAG queries. Once the query finishes and the results are safely indexed, the agent triggers `metorial_delete_server` to kill the instance. You get dynamic, on-demand data loading without the idle server bill.

Setup guide

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

Common questions about Metorial MCP in LlamaIndex

By feeding live telemetry into your index. Your agent uses `metorial_get_server_status` to check node health, ensuring your RAG pipelines get data from active, verified sources instead of guessing.

Yes. You can configure your agent to pull historical log boundaries using `metorial_list_traces`, index them, and then query that vector store to pinpoint recurring bottlenecks in your system.

You let the agent decide. When a user query demands live tool execution, the LlamaIndex agent runs `metorial_deploy_server` to stand up a container, executes the tool, and then tears it down.

Absolutely. You use `metorial_list_servers` to identify active workspaces, then limit your agent's access to only the specific tool execution boundaries it needs for the current task.

We use strict, single-tenant isolation for every instance. Your serverless container logs are encrypted in transit and never stored on shared disks, keeping your execution data completely segregated from other tenants.
