How to Use the Elastic Security MCP in LlamaIndex

Q: Can LlamaIndex help me find gaps in my Elastic Security coverage?

Yes, by indexing your rules from listdetectionrules and comparing them against threat reports. The LlamaIndex agent identifies missing MITRE TTPs and can suggest new ones via createrule.

Q: How does LlamaIndex handle exception auditing in Elastic Security?

The framework indexes exception lists retrieved from listexceptions to map bypass rules. Your agent queries this index to verify that whitelisted hostnames do not overlap with active threats.

Q: Can I run real-time signal analysis with LlamaIndex?

Yes, you query searchsignals through the McpToolSpec to fetch the latest security alerts. LlamaIndex feeds these raw payloads into the LLM context to generate instant incident summaries.

Index raw Elastic Security alerts and search rules semantically inside LlamaIndex.

Index security signals for semantic RAG

`search_signals` retrieves raw Elastic alerts and feeds them directly into your LlamaIndex vector store. This turns ephemeral security events into a searchable knowledge base of past incidents. Your agent queries this index to find historical patterns, matching new alerts against documented process trees. Grounding your security analysis in actual historical signal data prevents LLM hallucinations.

Query rule configurations semantically in LlamaIndex

`list_detection_rules` pulls all configured SIEM rules into LlamaIndex to build a unified index of your defensive posture. The framework maps your active rules against threat taxonomies like MITRE ATT&CK. Users query the index to ask which rules cover specific tactics, and the agent uses `get_rule` to pull exact query logic. This bridges the gap between raw query syntax and natural language security audits.

Audit exceptions and threat models

`list_exceptions` extracts your global bypass logic so LlamaIndex can index your whitelist configurations. The agent cross-references these exceptions with raw signals to find blind spots. It checks update requirements via `get_prepackaged_rules_status` to ensure your threat models are fresh. This MCP Server integration turns static configurations into interactive, queryable documents.

Setup guide

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

Common questions about Elastic Security MCP in LlamaIndex

Use the llama-index-tools-mcp package to connect the MCP Server and call `list_detection_rules`. The output is converted into document nodes and indexed for semantic search.

Yes, by indexing your rules from `list_detection_rules` and comparing them against threat reports. The LlamaIndex agent identifies missing MITRE TTPs and can suggest new ones via `create_rule`.

The framework indexes exception lists retrieved from `list_exceptions` to map bypass rules. Your agent queries this index to verify that whitelisted hostnames do not overlap with active threats.

Yes, you query `search_signals` through the McpToolSpec to fetch the latest security alerts. LlamaIndex feeds these raw payloads into the LLM context to generate instant incident summaries.

No, because your rule configurations, exception lists, and raw alerts are processed within a zero-trust, ephemeral sandbox. Vinkius handles authentication securely, meaning your SIEM API keys are never exposed to the LLM or stored in the index.
