## About

# External Attack Surface Management (EASM)

## Overview
EASM discovers external attack surface: exposed assets, findings, lookalike domains. Use for security posture assessment and shadow IT detection.

## MCP Tools
Available: `zeasm_list_findings`, `zeasm_get_finding_details`, `zeasm_get_finding_evidence`, `zeasm_get_finding_scan_output`, `zeasm_list_lookalike_domains`, `zeasm_get_lookalike_domain`, `zeasm_list_organizations`.

For full API endpoint reference, see ENDPOINTS.md in this skill directory.

## Authentication
OneAPI OAuth2. Base URL: `https://api.zsapi.net/easm/api/v1`

## Common Patterns
- List all findings sorted by severity
- Get evidence for a specific finding
- Monitor lookalike domains for brand protection

## Known Limitations
- All MCP tools are read-only
- No remediation actions via API (manual follow-up required)

## MCP Server

Live read operations for EASM are available via the [zscaler-mcp-server](https://github.com/zscaler/zscaler-mcp-server) (`easm_*` tools). This skill provides workflow guidance and context; the MCP server executes the API calls. See the MCP server repository for the full tool list and parameters.
