Overview

Description from the maker (original English)

AI threat hunting & incident response for Elasticsearch/OpenSearch with endpoint & network forensics

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Databases & datasets
  • You need to fill in: ELASTICSEARCH_API_KEY, ELASTICSEARCH_PASSWORD, ELASTICSEARCH_BEARER_TOKEN

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: ELASTICSEARCH_HOSTS, ELASTICSEARCH_CLOUD_ID, ELASTICSEARCH_API_KEY, ELASTICSEARCH_USERNAME, ELASTICSEARCH_PASSWORD, ELASTICSEARCH_BEARER_TOKEN, VERIFY_CERTS, REQUEST_TIMEOUT

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "crowdsentinel": {
      "command": "uvx",
      "args": [
        "crowdsentinel-mcp-server"
      ],
      "env": {
        "ELASTICSEARCH_HOSTS": "your-value",
        "ELASTICSEARCH_CLOUD_ID": "your-value",
        "ELASTICSEARCH_API_KEY": "your-value",
        "ELASTICSEARCH_USERNAME": "your-value",
        "ELASTICSEARCH_PASSWORD": "your-value",
        "ELASTICSEARCH_BEARER_TOKEN": "your-value",
        "VERIFY_CERTS": "your-value",
        "REQUEST_TIMEOUT": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add crowdsentinel --env ELASTICSEARCH_HOSTS=your-value --env ELASTICSEARCH_CLOUD_ID=your-value --env ELASTICSEARCH_API_KEY=your-value --env ELASTICSEARCH_USERNAME=your-value --env ELASTICSEARCH_PASSWORD=your-value --env ELASTICSEARCH_BEARER_TOKEN=your-value --env VERIFY_CERTS=your-value --env REQUEST_TIMEOUT=your-value -- uvx crowdsentinel-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "crowdsentinel": {
      "command": "uvx",
      "args": [
        "crowdsentinel-mcp-server"
      ],
      "env": {
        "ELASTICSEARCH_HOSTS": "your-value",

        "VERIFY_CERTS": "your-value",
        "REQUEST_TIMEOUT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "crowdsentinel": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "crowdsentinel-mcp-server"
      ],
      "env": {
        "ELASTICSEARCH_HOSTS": "your-value",

        "VERIFY_CERTS": "your-value",
        "REQUEST_TIMEOUT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is Crowdsentinel MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ELASTICSEARCH_API_KEY, ELASTICSEARCH_PASSWORD, ELASTICSEARCH_BEARER_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.6.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

CrowdSentinel MCP Server

AI-Powered Threat Hunting & Incident Response Framework

MCP Official Registry · PyPI Package

Open-source threat hunting orchestrator connecting LLMs to enterprise security data via Model Context Protocol (MCP)

What is CrowdSentinel?

CrowdSentinel transforms traditional SIEM querying into intelligent, framework-driven investigations using natural language. It serves as a unified security intelligence layer that connects large language models to enterprise security data sources, enabling:

  • Natural Language Threat Hunting — Query Elasticsearch using plain English
  • AI-Guided Investigation Workflows — Built-in prompts guide agents through proper IR methodology
  • Persistent Investigation State — Memory-managed IoC tracking, forensic timelines, and cross-query correlation that survives across sessions (8GB FIFO storage)
  • Cross-Tool IoC Correlation — IoCs discovered in one tool are automatically available to all others
  • Multi-Source Analysis — Elasticsearch, EVTX logs (Chainsaw), PCAP files (Wireshark), live endpoint forensics (Velociraptor), local host forensics (osquery)
  • Velociraptor Endpoint Forensics — 25 MCP tools for live artefact collection (processes, network, persistence, execution evidence, NTFS MFT, SRUM, remote EVTX) with automatic IoC extraction
  • Encoded-Command Deobfuscation — Automatically peels base64/UTF-16LE/gzip/hex layers off encoded commands (e.g. PowerShell -EncodedCommand) so C2 addresses hidden inside them surface as IoCs
  • Adaptive Schema Intelligence — Data-driven schema registry (ECS, Sysmon, Windows Security, auditd, Zeek, Packetbeat, AWS CloudTrail) adapts hunts to each index's field conventions
  • DFIR Knowledge Resources — 9 MCP resources exposing investigation playbooks, Pyramid of Pain reference, and cross-correlation guidance directly to connected AI agents
  • Standalone CLI — Full threat hunting from the terminal without an MCP client

Installation

Install from PyPI (recommended)
# Install with pip

pip install crowdsentinel-mcp-server

Or install with uv

uv pip install crowdsentinel-mcp-server

Download detection rules, Chainsaw, and Sigma rules (one-time)

crowdsentinel setup

Validate connector configuration and readiness (offline, no external calls)

crowdsentinel doctor

Optional extras:

# Velociraptor live endpoint forensics (adds 25 MCP tools)

pip install 'crowdsentinel-mcp-server[velociraptor]'

Long-tail deobfuscation coverage via chepy (XOR, exotic encodings).

The stdlib decoder core works without this — chepy only extends it.

pip install 'crowdsentinel-mcp-server[deobf]'

Detection rules (6,060 Lucene + EQL + ES|QL) are bundled with the package — no download needed. The setup command downloads additional tools:

  • Chainsaw binary for EVTX analysis
  • 3,000+ Sigma rules for Chainsaw

Downloaded tools are stored in ~/.crowdsentinel/ and persist across package upgrades.

System dependency for PCAP analysis:

# Required for network traffic analysis and cross-tool IoC correlation

sudo apt install tshark # Debian/Ubuntu/Kali sudo dnf install wireshark-cli # Fedora/RHEL brew install wireshark # macOS

Run directly with uvx (no install needed)
# Elasticsearch 8.x (default)

uvx crowdsentinel-mcp-server

Other backends

uvx crowdsentinel-mcp-server-es7 # Elasticsearch 7.x uvx crowdsentinel-mcp-server-es9 # Elasticsearch 9.x uvx opensearch-mcp-server # OpenSearch 1.x/2.x/3.x

Install from source
git clone https://github.com/thomasxm/CrowdSentinels-AI-MCP.git

cd CrowdSentinels-AI-MCP chmod +x setup.sh && ./setup.sh

Or install everything, including all optional extras (deobf/chepy, velociraptor)

./setup.sh --full

The setup script will:

  • Install dependencies (pipx, uv, Claude Code CLI if needed)
  • Bundle 6,060 detection rules and download Chainsaw binary
  • Prompt for Elasticsearch credentials (never hardcoded)
  • Configure the MCP server with Claude Code
  • Validate your connection

With --full, every optional extra is installed too, so all 139 MCP tools have their dependencies available — the recommended mode for a production-ready server.
