FortiCNAPP MCP Server

MCP server for managing Fortinet FortiCNAPP (Cloud Native Application Protection Platform) via AI agents. Built with FastMCP, deployed as a container.

FortiCNAPP (powered by Lacework) provides cloud security capabilities including vulnerability scanning, agent management, and compliance monitoring.

Tools

Tool	Description
cnapp_health_check	Check FortiCNAPP service health and connectivity
cnapp_validate_config	Validate configuration settings and credentials
cnapp_get_agent_tokens	Retrieve agent access tokens
cnapp_scan_image_vulnerabilities	Scan container images for vulnerabilities

Every tool accepts optional cnapp_key_id, cnapp_key_secret, and cnapp_base_url parameters. If not provided, the server reads from environment variables. Per-call parameters override environment variables.

Test with curl

# 1. Initialize session and capture Mcp-Session-Id from headers
export SESSION_ID=$(curl -s -i -X POST https://mcp-forticnapp.fortidemoscloud.com/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test-curl","version":"1.0"}}}' \
  | grep -i "mcp-session-id" | awk '{print $2}' | tr -d '\r')

echo "Session ID: $SESSION_ID"

# 2. List tools using the captured Session ID
curl -s -X POST https://mcp-forticnapp.fortidemoscloud.com/mcp \
  -H "Content-Type: application/json" \
  -H "Mcp-Session-Id: $SESSION_ID" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'

# 3. Call a tool (health check)
curl -s -X POST https://mcp-forticnapp.fortidemoscloud.com/mcp \
  -H "Content-Type: application/json" \
  -H "Mcp-Session-Id: $SESSION_ID" \

Environment Variables

Variable	Required	Default	Description
FORTICNAPP_KEY_ID	Yes	—	Lacework API key ID
FORTICNAPP_KEY_SECRET	Yes	—	Lacework API key secret (X-LW-UAKS value)
FORTICNAPP_BASE_URL	No	lwintseemea-eu.lacework.net	Lacework API base URL or FQDN. Can be a full URL (https://myaccount.lacework.net) or just the FQDN (myaccount.lacework.net) — https:// is auto-prepended if missing.

Tool Parameters

cnapp_health_check / cnapp_validate_config / cnapp_get_agent_tokens

Parameter	Required	Description
cnapp_key_id	No	FortiCNAPP API key ID (uses FORTICNAPP_KEY_ID env var if not provided)
cnapp_key_secret	No	FortiCNAPP API key secret (uses FORTICNAPP_KEY_SECRET env var if not provided)
cnapp_base_url	No	FortiCNAPP API base URL or FQDN (e.g., myaccount.lacework.net). https:// is auto-prepended if missing. Uses FORTICNAPP_BASE_URL env var if not provided.

cnapp_scan_image_vulnerabilities

Parameter	Required	Default	Description
image_digest	Yes	—	Docker image digest (e.g., sha256:abc123...)
cnapp_key_id	No	—	FortiCNAPP API key ID
cnapp_key_secret	No	—	FortiCNAPP API key secret

days_back	No	3	Number of days to look back for scan data
deduplicate	No	true	Remove duplicate vulnerabilities across layers

Authentication

The server uses Lacework bearer token authentication:

1. Token Generation: Uses FORTICNAPP_KEY_SECRET (X-LW-UAKS header) and FORTICNAPP_KEY_ID to request bearer tokens from /api/v2/access/tokens
2. Token Caching: Automatically caches tokens and refreshes before expiration (with 60s buffer)
3. API Calls: All Lacework API calls use the cached bearer token in the Authorization: Bearer <token> header
4. Retry Logic: Automatic retry with exponential backoff for transient failures
5. URL Normalization: FORTICNAPP_BASE_URL accepts either a full URL (https://myaccount.lacework.net) or just the FQDN (myaccount.lacework.net) — the https:// scheme is always auto-prepended if missing
