About Chronicle SecOps MCP Server

What is Chronicle SecOps MCP Server: Automating Context-Rich Threat Detection?

Chronicle SecOps MCP Server is a purpose-built Model Context Protocol (MCP) server designed to seamlessly integrate with Google's Chronicle Security Operations platform. It enables automated, context-driven threat detection by exposing Chronicle's security data and capabilities through standardized API endpoints. This server acts as a bridge, empowering tools like Claude Desktop to query and analyze security events, alerts, and indicators of compromise (IoCs) with minimal manual intervention.

How to Use Chronicle SecOps MCP Server: Automating Context-Rich Threat Detection?

Deployment follows a structured workflow:

Installation: Choose between automated Smithery-based installation or manual setup using Python pip. Ensure Python 3.11+ and valid Google Cloud credentials are in place.
Configuration: Modify claude_desktop_config files to register the server, specifying endpoints for event logging, alert analysis, and IOC lookups.
Execution: Launch the server and initiate API calls via tools like Postman or custom scripts to retrieve real-time threat context. For example:
```
curl -X GET "http://localhost:8080/chronicle/alerts?severity=high"
```

Chronicle SecOps MCP Server Features

Key Features of Chronicle SecOps MCP Server: Automating Context-Rich Threat Detection?

Context Enrichment: Automatically correlates events across Chronicle's unified dataset, including logs, endpoints, and network traffic

Installing in Claude Desktop

To use this MCP server with Claude Desktop:

Install Claude Desktop
Open Claude Desktop and select "Settings" from the Claude menu
Click on "Developer" in the lefthand bar, then click "Edit Config"
Update your claude_desktop_config.json with the following configuration (replace paths with your actual paths):

{
  "mcpServers": {
    "secops-mcp": {
      "command": "/path/to/your/uv",
      "args": [
        "--directory",
        "/path/to/your/mcp-secops-v3",
        "run",
        "secops_mcp.py"
      ],
      "env": {
        "CHRONICLE_PROJECT_ID": "your-google-cloud-project-id",
        "CHRONICLE_CUSTOMER_ID": "your-chronicle-customer-id",
        "CHRONICLE_REGION": "us"
      }
    }
  }
}

Make sure to update:

* The path to `uv` (use `which uv` to find it)
* The directory path to where this repository is cloned
* Your Chronicle credentials (project ID, customer ID, and region)

Save the file and restart Claude Desktop
You should now see the hammer icon in the Claude Desktop interface, indicating the MCP server is active
