cato-mcp-server

Cato MCP CMA

A Model Context Protocol (MCP) server implementation that integrates with Cato CMA Public API.

Overview

This server implements the Model Context Protocol to allow AI assistants to interact with Cato's GraphQL API.
It provides tools that enable AI models to query and retrieve information from Cato systems in a standardized way.

The provided MCP server has been tested for compatibility with popular MCP clients (non-free tier) - such as Cursor and Claude Desktop using the Claude Sonnet 4 model, and is recommended for use with these clients.

The server is available as a docker image at ghcr.io/catonetworks/cato-mcp-server

Add the following to Claude-Desktop config file:\

MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "cato": {
      "command": "docker",
      "args": [
          "run",
          "--rm",
          "--pull",
          "always",
          "-i",
          "-e", "CATO_API_HOST=<your Cato API Host>",
          "-e", "CATO_ACCOUNT_ID=<your Cato Account ID>",
          "-e", "CATO_API_KEY=<your Cato API Key>",
          "ghcr.io/catonetworks/cato-mcp-server:latest"
      ],
      "disabled": false,
      "autoApprove": []
    }
  }
}

Notes:

• The --pull always option ensures that the AI Agent application (e.g. Claude-Desktop) uses cato-mcp-server's most updated version.
  The AI Agent application running cato-mcp-server might open a popup asking for permissions to access data from other apps.\

\

• If you don't wish to allow this, you can remove the --pull always option, but then you will need to manually update the image when a new version is released by executing:

docker pull ghcr.io/catonetworks/cato-mcp-server:latest

Configuration

The server requires the following environment variables:

# The hostname of the Cato API (without protocol). e.g.: api.catonetworks.com
# For details about your Cato API hostname, please see: https://support.catonetworks.com/hc/en-us/articles/20564679978397-What-is-the-Cato-API
CATO_API_HOST: "api.catonetworks.com"
# The Cato account-id
CATO_ACCOUNT_ID: "1234567"
# The Cato API-KEY for authentication
CATO_API_KEY: "123abc"

Available Tools

Category	Tool	Description
Entity Lookup	entity_lookup	Retrieve a list of entities of a specific type (e.g., users, sites, services),with optional filtering (e.g., by name) and pagination support.
Sites	sites_by_location	Returns site data enriched with geographic location and associated PoP connectivity information.
	site_details	Retrieves comprehensive site details including operational status, connectivity status, High Availability (HA) information, and device interface statuses.
	site_types	Provides details for all configured sites, including connection methods (e.g., Socket, IPSEC, vSocket).
	socket_versions	Lists version information for all deployed Sockets, including site association.
	wan_connectivity	Provides real-time metrics for WAN links at each site, including traffic volume, packet loss, latency, and jitter, to assess link performance and health.
Users and Clients	user_details	Provides profile and status information for connected remote users, including device name, operating system, and connection status.
	user_connection_details	Offers session-specific data for connected remote users, such as uptime, connection duration, and associated PoP details.
	user_software_versions	Lists operating system and Cato Client version information for connected remote users.
Site Metrics	site_network_health	Retrieves a summary of network health for sites over a specified time frame, identifying sites with poor network quality (high packet loss, latency, jitter).
	top_site_bandwidth_consumers	Ranks sites by total traffic (bytesUpstream + bytesDownstream) in a given time frame for capacity planning and traffic analysis.
	site_metrics_timeseries	Retrieves time-bucketed metrics data for sites, enabling trend analysis, peak detection, and traffic pattern identification.
	site_metrics	Returns aggregated metrics for sites (no timeseries data).
	site_metrics_summary	Provides aggregated metrics analysis for sites grouped by various dimensions like site type, connection type, region, or interface role.
	annotation_event_counter	Analyzes infrastructure change events and annotations to track stability and identify sites with frequent changes or issues.
User Metrics	top_users_bandwidth_consumers	Ranks VPN-connected users by total traffic (bytesUpstream + bytesDownstream) in a given time frame for bandwidth monitoring, cost management, and identifying unusual usage patterns.
	user_metrics_timeseries	Retrieves time-bucketed metrics data for VPN-connected users, enabling trend analysis and performance monitoring over time.
	user_metrics	Returns aggregated metrics for VPN-connected users (no timeseries data).
